How to Replace Mercedes-Benz Sprinter Headlights

Mercedes-Benz Sprinter headlight replacement is straightforward following premium manufacturer standards. Whether replacing standard halogen units or upgrading to LED or Multibeam LED headlights with adaptive main beams, this guide covers all Sprinter panel van, passenger van, crew van, and chassis cab variants.

Step-by-Step Instructions:

1. Open the bonnet and secure it safely with the prop rod. The Mercedes-Benz Sprinter has excellent bonnet access typical of premium large commercial vehicles with German engineering standards. Locate the rear of the headlight assembly from within the engine bay. The headlight mounting area is very accessible from above with clear visibility of all fixings reflecting Mercedes-Benz's focus on serviceability despite premium positioning.
2. Disconnect all electrical connectors from the headlight. Mercedes-Benz Sprinter headlights typically have 2-4 electrical connectors depending on specification including main beam, dipped beam, side light, and on higher trim levels additional connectors for LED daytime running lights or Multibeam LED adaptive systems. Press the release tabs on each connector carefully and pull straight out ensuring you support the connector housing to avoid damaging the locking mechanism. On models with advanced lighting systems the connectors may have additional safety locks requiring careful manipulation. Handle all connectors gently as Mercedes electrical connections are precision-engineered but can become brittle with age on higher-mileage examples.
3. Remove the headlight mounting bolts. The Sprinter uses high-quality Torx screws to secure the headlight assembly, typically T20, T25, or T30 depending on model year, with usually 2-4 bolts along the top edge easily accessible once the bonnet is open. Mercedes-Benz engineering ensures mounting bolt locations are logical and accessible. Remove all mounting bolts completely and keep them organized for refitting as Mercedes fasteners are high-quality and should be reused unless damaged. The mounting design is robust and straightforward reflecting the brand's commercial vehicle heritage.
4. Release any additional clips or retainers. Some Mercedes-Benz Sprinter headlights use supplementary plastic clips at various points around the headlight perimeter for additional security and alignment. Check for clips at the inner corner near the grille and along the bottom edge. Work carefully as clips can become brittle with age especially on vans operating in harsh commercial environments with extreme temperatures. If clips break during removal, genuine Mercedes replacement clips are available from dealers and provide proper fitment though aftermarket alternatives may also work.
5. Carefully remove the headlight assembly from the vehicle. With all bolts and clips released, gently pull the headlight straight forward out of its mounting position. Mercedes-Benz headlights slide forward on precision locating pins that ensure correct alignment maintaining the tight panel gaps and premium appearance Mercedes is known for. Support the weight of the headlight as you pull to prevent dropping as Sprinter headlights are substantial units especially LED and Multibeam variants. If you feel resistance, stop immediately and check for missed fixings rather than forcing which could damage mounting points, the headlight housing, or expensive LED components.
6. Transfer components to new headlight if needed. If your replacement headlight doesn't include bulbs, LED modules, or other components, carefully transfer these from the old unit following Mercedes specifications. When handling halogen or LED bulbs, wear clean gloves to avoid touching glass surfaces or LED components with bare hands as skin oils cause premature failure. Check that all seals and gaskets are in good condition when transferring components to ensure weatherproofing meets Mercedes standards. On Multibeam LED headlights, components are typically integrated and non-serviceable requiring complete headlight replacement which can be expensive.
7. Install the new headlight assembly. Reverse the removal process by aligning the new headlight with precision mounting pins and push firmly into place ensuring all locating pins engage correctly in their mounting holes. The tight tolerances of Mercedes engineering mean alignment must be precise to maintain proper panel gaps. Refit all mounting bolts and tighten to proper torque specifications (typically 8-10 Nm for headlight mounting bolts though check workshop manual for your specific model year). Reconnect all electrical connections ensuring each clicks firmly into place and any safety locks are properly engaged. Test all lighting functions before final assembly including dipped beam, main beam, side lights, indicators, and daytime running lights. On models with adaptive lighting systems, the headlights may require initialization drive cycle or dealer coding to function correctly. Check headlight alignment after fitting using adjustment screws on the rear of the assembly and consider professional alignment check especially for LED and Multibeam systems.

Important Notes: Mercedes-Benz Sprinter headlight replacement follows premium manufacturer standards with emphasis on precision and quality. When handling new headlights, never touch lens, reflector surfaces, or LED modules. Advanced lighting systems including Multibeam LED with adaptive main beams may require Mercedes STAR diagnostic system coding after replacement to activate all functions and avoid warning lights on dashboard. Proper headlight alignment is crucial for optimal visibility, oncoming driver safety, and MOT compliance. Mercedes-Benz dealers can perform precision headlight alignment using specialized equipment though most standard replacements don't require adjustment if mounting pins are properly engaged. Genuine Mercedes headlights ensure perfect fit and function though pattern parts may offer cost savings with some compromise on quality and longevity.

How to Replace Mercedes-Benz Vito Front Bumper

Replacing a Mercedes-Benz Vito front bumper is achievable in 60-90 minutes depending on specification and experience level. This process covers both diesel and electric eVito variants as they share identical body panels. The procedure applies to panel van, crew van, and passenger variants across all three available body lengths.

Step-by-Step Instructions:

1. Open the bonnet and secure it with the prop rod. Locate the upper bumper mounting fixings along the top edge just below the distinctive Mercedes-Benz grille with three-pointed star. The Vito typically has 4-6 Torx screws or bolts securing the top edge of the bumper. These are usually T20, T25, or T30 Torx screws depending on model year and trim level, clearly visible once the bonnet is open. Remove all upper fixings systematically and keep them organized as Mercedes fasteners are high-quality and should be reused for proper torque specifications during refitting.
2. Access the wheel arch areas on both sides. Turn the steering wheel fully to one side to maximize access to the wheel arch liner. Behind each front wheel, locate the plastic arch liner which provides access to side bumper mounting points. Remove or release 2-4 plastic clips or screws securing the front section of the arch liner to expose the side bumper fixings. Mercedes-Benz uses high-quality plastic push-in clips that release by pressing the center pin first then pulling the outer clip, though some may use Torx screws. Repeat the process on both driver and passenger sides taking care not to damage the arch liner as replacement can be expensive.
3. Remove the side mounting screws from both wheel arches. Behind each wheel arch liner you'll find 2-4 screws or bolts securing each side of the bumper to the wing and chassis. These are usually Torx screws on Mercedes-Benz Vito vans maintaining the brand's preference for Torx fasteners throughout. Remove all side fixings on both sides and keep track of which fixings came from which location as Mercedes engineering sometimes uses different fastener types or lengths on driver versus passenger sides for specific reasons related to component packaging.
4. Remove undertray screws and lower bumper fixings. Get underneath the vehicle safely using quality ramps or jack stands never work under a vehicle supported only by a jack as this is extremely dangerous. Locate and remove all screws and clips securing the engine undertray and lower edge of the bumper. The Mercedes-Benz Vito typically uses 6-10 fixings along the bottom edge which may be Torx screws or high-quality plastic push-in clips. You don't always need to remove the entire undertray, just the front section that overlaps with the bumper, though full undertray removal provides better access and is recommended for inexperienced technicians.
5. Disconnect fog lights, sensors, and electrical connections. Reach behind the bumper and disconnect all electrical connectors with care. This includes fog light connections if fitted (Premium trim typically includes fog lights), parking sensor connections if equipped with parking assist which is common on Progressive and Premium trim Vito models, and any additional connections for cameras on models with advanced driver assistance systems or 360-degree parking camera systems available on higher specifications. Mercedes-Benz electrical connectors use high-quality locking mechanisms so press release tabs carefully and pull straight out without forcing or twisting. Count how many connections you disconnect to ensure you reconnect them all during refitting as missing connections will trigger warning lights on the advanced MBUX dashboard display.
6. Release the bumper side clips and mounting tabs. Mercedes-Benz Vito bumpers are secured by precision-engineered plastic clips or metal brackets on each side that slot into the wing panels maintaining tight panel gaps characteristic of premium German engineering. With all fixings removed, firmly but gently pull the bumper forward from one corner while supporting the opposite side. You may need to wiggle slightly from side to side to release the clips which are designed to hold firmly for durability. Listen for clicks as clips disengage. The bumper should come free relatively easily once all fixings are removed though the precision fit means it may feel tighter than mass-market vans.
7. Remove the bumper completely from the vehicle. With all fixings removed and clips released, carefully pull the bumper straight forward away from the vehicle. Mercedes-Benz Vito bumpers are reasonably large and substantial, benefiting from a second person to help support and maneuver the bumper clear of the vehicle especially on long wheelbase L3 variants. Place the removed bumper on a protected surface or hang it safely to avoid scratching the painted surface which on Premium trim includes body-colored finish requiring extra care, or damaging any components attached to it including expensive parking sensors or fog lights.
8. Prepare and fit the replacement bumper assembly. Before installation, transfer any brackets, trim pieces, fog lights, parking sensors, or other components from the old bumper if not already fitted to your replacement. Mercedes-Benz components are precisely engineered so ensure all parts transfer correctly maintaining proper alignment. Align the new bumper with mounting points and push firmly into place ensuring all side clips engage properly into the wing mounting points which requires precision due to tight Mercedes tolerances. Reconnect all electrical connections including fog lights and parking sensors ensuring each connector clicks firmly and any locking tabs are properly engaged. Systematically secure the bumper with all screws and clips in reverse order of removal, starting with side fixings, then top fixings, then undertray fixings, torquing fasteners to proper specifications. Test all electrical functions before final assembly including fog lights, parking sensors, and any camera systems. Check panel gaps are even on both sides and adjust if necessary before final tightening as Mercedes-Benz is known for precise panel alignment.

Top Tips: Mercedes-Benz Vito bumpers follow premium German engineering standards with emphasis on precision fit and finish. When refitting parking sensors, ensure each sensor clicks firmly into its mounting hole and is correctly aligned flush with the bumper surface as Mercedes parking systems are calibrated for precise sensor positioning. Some Mercedes-Benz Vito models have front-mounted cameras for 360-degree parking systems or active driver assistance features which may require recalibration at a Mercedes-Benz dealer using STAR diagnostic system after bumper replacement. Check all panel gaps between bumper and wings are even before final tightening of all fixings as uneven gaps will be visually obvious on premium vehicle and may indicate misaligned mounting clips. The build quality and precision engineering of Mercedes-Benz means replacement bumpers, especially genuine parts, typically fit excellently without extensive adjustment though pattern parts may require more fitting work.

Common Mercedes-Benz Van Parts Problems & Solutions

Mercedes-Benz commercial vehicles are renowned for exceptional reliability and premium engineering quality. The Sprinter has been named the UK's most reliable large van in the annual FN50 survey repeatedly for multiple consecutive years, while the Vito regularly finishes in the top 10 of the same survey demonstrating consistent quality across the range. Mercedes-Benz vans frequently exceed 300,000-400,000 miles with proper maintenance, showcasing legendary durability. However, certain components can experience specific issues. Here are the most commonly reported Mercedes-Benz van parts problems based on verified data from UK operators, mechanics, and industry specialists.

Mercedes-Benz Sprinter Reliability (UK's Most Reliable Large Van - FN50 Champion):

• Outstanding Reliability Record: The Mercedes-Benz Sprinter has long been the van with the best reputation for reliability in the UK market, repeatedly coming top in the annual FN50 van reliability survey for multiple consecutive years establishing it as the benchmark all other large vans are measured against. Parkers magazine states there seems to have been no change to this outstanding performance with the introduction of the 2018-onwards model (907 generation). If you want a reliable van, the Sprinter should be your first port of call according to industry experts. The Sprinter frequently exceeds 300,000-400,000 miles with proper maintenance, with many owners including those living full-time in converted Sprinter campervans reporting high mileage without significant issues demonstrating exceptional durability and longevity.
• Premium Engineering and Build Quality: The Sprinter is comfortable, easy to drive, and exceptionally well-equipped as standard with advanced MBUX infotainment system featuring 7-inch or 10-inch touchscreen with intuitive navigation and voice command capabilities. The cabin blends clever functionality with high level of comfort, with ergonomic design, quality materials, and thoughtful storage options. Mercedes-Benz's attention to detail and commitment to combining luxury with utility creates a workspace on wheels that doesn't compromise on aesthetics or functionality. The Sprinter offers hundreds of different configuration options including panel van, passenger van, crew van, chassis cab, and new tractor head configurations with multiple wheelbase lengths, body lengths, and roof heights allowing perfect customization for specific business needs.
• Common Issues Despite Excellent Reliability: While the Sprinter's reliability is outstanding, it's not perfect. The 2018 model year (first year of 907 generation production) was subject to quite a long list of safety recalls according to UK government official vehicle recall website, though most of these only impacted small numbers of vans and appear to be mostly teething issues related to building the new model. Subsequent model years have had far fewer recalls supporting the teething issue theory. Edmunds consumer reviews show overall sentiment is mixed with owners praising roomy interiors, power, and high-tech features but complaining about high repair costs, parts availability issues, and unreliable performance especially with emissions system. Many find the van's handling in tough weather and complex technology frustrating, making some owners suggest considering other options. The diesel particulate filter and AdBlue emissions systems can be problematic requiring expensive repairs when faults occur.
• Running Costs and Maintenance: Official Mercedes-Benz parts and service centers can be considerably pricier than competitors reflecting superior quality and craftsmanship but increasing total cost of ownership. Repair costs are high when issues occur though frequency of repairs is low due to excellent reliability. It's recommended to service your Sprinter at least once a year to maintain peak condition and preserve the legendary reliability. The Sprinter's Euro 6 diesel engines are renowned for longevity often covering over 300,000 miles with proper maintenance according to Zego insurance provider research, exceeding the Ford Transit's newer models reaching well over 200,000 miles with proper care. The 3-year unlimited mileage warranty provides reassurance though shorter than some competitors.

Mercedes-Benz Vito Reliability (Top 10 Finisher - Premium Quality):

• Very Good Reliability: The Mercedes-Benz Vito doesn't have quite such a shining record for reliability as its bigger stablemate the Sprinter according to What Car? magazine. However, its reputation is still pretty decent and it frequently finishes in the top 10 of industry reliability surveys. The Vito always performs well in the FN50 van reliability survey though not as well as Sprinter which consistently finishes as number one most reliable van in the UK according to Parkers magazine. This demonstrates the Vito is significantly more reliable than average medium vans while not quite matching the Sprinter's legendary status.
• 2024 Facelift Safety Improvements: The 2024 update brought huge improvement as far as Vito's safety is concerned with greater degree of driver assistance kit. This resulted in the van earning the highest level of rating from Euro NCAP with Platinum score and 90% rating. At time of writing there are only a few vans that have done better than the Vito's 90% rating. The previous Mercedes-Benz Vito was subjected to Euro NCAP's commercial vehicle tests under 2023 protocols and was awarded Silver status. The latest version however tested against tougher 2024 protocols and earned Platinum status which is the highest rating you can get. Thankfully the majority of safety-related equipment comes as standard including preventative driver aids and reactive protective features.
• Premium Positioning and Cost: A Mercedes-Benz Vito costs spec-for-spec around £3,000 more than Britain's favorite van the Ford Transit Custom according to Top Gear magazine. As a raw business case workhorse it doesn't add up. However there is image and badge appeal at play with the dinner plate-sized three-pointed star on the grille. Behind the Mercedes air of superiority there is substance with the best thing about the Vito being its comfort. The ride and effortless punch of the larger diesel engines make it genuinely soothing machine to command. The Vito holds its value well, looks smart, and the premium branding will project strong image of your business.
• Driving Experience and Quality: The Vito has good all-round visibility and is great to drive with well-weighted steering and good ride quality. It's not as sharp or as smooth as the Ford Transit Custom but there isn't large gulf between the two and it remains composed and comfortable both laden and unladen according to Honest John. The reversing camera is among best-in-class with better field of vision and greater accuracy when parking and maneuvering than rival systems. The 2.0L OM624 diesel engine is flexible unit with five power outputs available. The six-speed manual models are smooth and responsive but the 9-speed 9G-TRONIC automatic transmission is the star of the range from behind the wheel with transmission so quick that changes are barely noticeable.

Mercedes-Benz Citan Reliability (Good But Issues Present - Renault Base):

• Renault Platform with Mercedes Quality: The Mercedes-Benz Citan is based on Renault Kangoo and Nissan Townstar platform but second generation launched 2021 saw Mercedes much more actively involved in engineering the vehicle from the start. As result it looks very much in keeping with every other modern Mercedes product and feels more substantially like high-quality product from moment you get in and start driving. Mercedes is noted as reliable brand in general in annual FN50 van reliability survey regularly finishing right up the top with Sprinter named most reliable for several years. Although much of Citan is based on Renault technology Mercedes reputation for high-quality aftercare should see you right whatever happens.
• Common Citan Problems: Despite Mercedes quality improvements the Citan experiences several common issues. DPF clogging is frequent problem with diesel particulate filter failures affecting vans on short urban trips where exhaust never gets hot enough to burn off deposits. Regular long drives help regenerate filter and prevent costly repairs. Turbocharger failures in diesel models occur due to oil contamination or debris buildup causing power loss and increased fuel consumption. Timing chain elongation on petrol engines (not available UK but worth noting) leads to rattling noises and potential engine damage. Fuel injector faults cause rough idling, poor acceleration, and increased emissions requiring regular maintenance and quality fuel to maintain injector performance.
• Transmission and Starting Issues: The automatic transmission on Citan 112 model exhibits irregular shifting problems and loss of power with complaints often manifesting between 40,000-60,000km potentially leading to complete transmission failure. Gearbox can feel less than slick with owners complaining about stiff shifts or spongy clutch especially in traffic. Engine starting problems particularly affect 109 CDI and 111 CDI diesel variants with diesel engine often having starting problems especially in these variants manifesting as complete failure to start or delayed starting reactions. Symptoms can occur after as little as 15,000-25,000km. Starter motor failures are frequent with starter not turning or not responding to ignition signal at all particularly affecting Tourer variants and occurring after only 20,000-30,000km with problems worsening considerably in cold temperatures below 5°C.
• Additional Citan Issues: Air conditioning system loses cooling capacity especially in 108 CDI and 111 CDI variants. Suspension designed to navigate European city cobblestones can start articulating displeasure through creaks, groans, and squeaks with heavy loads or rough roads wearing out springs and dampers. Brake shimmy through pedal occurs due to warped discs or tired pads. Sliding door can jam due to dirt in runners or worn-out mechanisms. Uneven tire wear often tied to misalignment or overloading. Heater issues with blocked matrices or failed fans. Rust can appear on wheel arches, door edges, and sills especially in damp salty climates despite Mercedes typically fending off rust well. Radio and infotainment failures whether blown fuse, software failure, or defective cables.

General Mercedes-Benz Van Ownership:

• Warranty and Service: All Mercedes-Benz vans come with 3-year unlimited mileage warranty which is excellent coverage providing peace of mind though some competitors offer longer warranty periods. Mercedes offers flexible servicing and maintenance with service intervals varying by model. Sprinter should be serviced at least once a year. Vito service intervals aren't specified in sources but likely similar. Citan requires service every 2 years or 18,000 miles whichever comes first. All models include breakdown cover and roadside assistance for 3 years as part of warranty package.
• Parts Pricing: Official Mercedes-Benz parts and service centers are considerably pricier than competitors reflecting superior quality and craftsmanship but significantly increasing running costs. When repairs are needed they are expensive due to premium parts pricing and specialist labor rates. However frequency of repairs is low due to excellent reliability especially on Sprinter models meaning total cost of ownership can be competitive despite higher per-repair costs. Pattern parts and aftermarket alternatives offer cost savings though may compromise on quality, fit, and longevity compared to genuine Mercedes components.

Prevention and Maintenance:

Maximizing Mercedes-Benz Van Reliability: To ensure maximum reliability from Mercedes-Benz vans, adhere strictly to manufacturer service schedules without extending intervals as Mercedes engineering requires proper maintenance to deliver legendary longevity. Use only high-quality diesel fuel and genuine or OE-quality parts as Mercedes engines have tight tolerances sensitive to fuel and oil quality. For Sprinter and Vito models, address any emissions system warning lights immediately as DPF and AdBlue faults can escalate into expensive repairs if ignored. Monitor coolant levels and condition regularly. For Citan models, take longer drives regularly to prevent DPF clogging if operating primarily in urban environments, perform timely oil changes using correct specification oil to prevent turbocharger failures, and address any starting issues immediately before they worsen. When buying used Mercedes-Benz vans, prioritize full dealer service history as this maintains warranty validity and demonstrates proper care, verify all recalls have been completed by checking UK government recall website, and have pre-purchase inspections performed by Mercedes specialists or authorized workshops familiar with brand-specific issues. Mercedes-Benz vans offer exceptional reliability when properly maintained with Sprinter leading the UK market for dependability and Vito providing premium alternative to mass-market medium vans, while Citan brings three-pointed star prestige to small van segment despite Renault mechanical base.
