Mercedes-Benz servicing, diagnostics & repairs
Manufacturer-standard servicing and main-dealer level diagnostics for every Mercedes, from the A-Class to AMG, with your digital service record kept up to date.
Your independent Mercedes garage
Mercedes servicing at local garage prices
Langs Automotive looks after Mercedes-Benz cars and vans from across Dorset and Hampshire from our workshop at Three Legged Cross, near Wimborne. Our qualified technician Chris works on the whole range, from hatchbacks and saloons to the sports models, including the high-performance AMG range.
We service your Mercedes with dealer-grade diagnostic equipment, which means we can put the service onto the Mercedes digital service record and keep your history complete. You get the standard you'd expect from a main dealer without the main-dealer labour rates.
Many Mercedes-Benz models also benefit from an automatic gearbox oil change on 7G-Tronic and 9G-Tronic gearboxes, and engine walnut blasting to remove carbon from direct-injection petrol engines. For warning lights and electrical faults, our vehicle diagnostics read Mercedes-specific fault codes across every module. An MOT can be booked alongside your service.
We also look after Sprinter and Vito vans through our commercial vehicle servicing, and Sprinter-based motorhomes through our motorhome and campervan servicing.

Diagnostics & programming
Main-dealer diagnostics, local garage prices
A modern Mercedes runs on dozens of control units, from the engine and gearbox to the SAM modules, air suspension, driver assistance and the COMAND or MBUX infotainment. A generic code reader only sees a fraction of them. Our dealer-level equipment reads Mercedes-specific fault codes across every module, so we can:
- Read and clear Mercedes fault codes in every module
- Code and programme replacement parts
- Reset the service indicator and update the digital service record
- Track down intermittent electrical faults
Warning light on, or a fault that keeps coming back? Book our vehicle diagnostics and we'll find the cause before anything gets replaced.
What we see on the ramp
Common Mercedes faults we fix
Injector seal leaks on CDI diesels
On older CDI diesels the injector seals can fail and let combustion gas escape, leaving a build-up of black carbon around the injectors. A ticking or chuffing noise and a diesel smell in the cabin are the signs. Left alone, the injectors can seize in the head.
Timing chain stretch
Some Mercedes petrol engines, notably the M271 four-cylinder in many C-Class, E-Class and SLK models, are known for timing chain stretch. A rattle on a cold start or a camshaft fault code are the early warnings.
7G-Tronic gearbox faults
Harsh or delayed shifts, or the gearbox dropping into limp mode, often trace back to the conductor plate, valve body or old fluid. We diagnose the cause first. Regular automatic gearbox oil services help keep it shifting smoothly.
AdBlue, NOx sensor & DPF faults
BlueTEC and later diesels, Sprinters and Vitos included, can throw AdBlue and NOx sensor faults, and short journeys clog the DPF. Ignore the countdown warning and the engine may not restart. See vehicle diagnostics.
Airmatic air suspension
Air suspension on models such as the E-Class, S-Class and the larger SUVs can develop leaking struts or a tired compressor. A car sitting low after being parked overnight is the classic sign.
Electrical, SAM & ignition faults
SAM control units, battery drain, key and ignition switch problems and warning lights that come and go. Our dealer-level equipment reads Mercedes-specific fault codes across every module, not just the engine.

Mercedes-AMG
AMG servicing done properly
AMG models are built for performance and they need more than a basic oil change. We service them to schedule with the oil grade the engine calls for, keep the automatic gearbox shifting cleanly with a gearbox oil service, clear carbon from direct-injection engines with walnut blasting, set the geometry with laser wheel alignment and, if you want more, offer performance remapping.

Mercedes servicing FAQs
Will an independent service affect my Mercedes warranty?
No. UK competition law lets you have your car serviced by an independent garage without affecting the manufacturer warranty, as long as the work follows the manufacturer's schedule and uses parts of matching quality. We service to the Mercedes-Benz schedule and record every service properly.
Can you update the Mercedes digital service record?
Yes. Our dealer-grade diagnostic equipment lets us put your service onto the Mercedes digital service record, so your history stays complete for your warranty and when you come to sell.
What is the difference between a Mercedes Service A and Service B?
Service A is the smaller service: engine oil, oil filter, a new sump plug washer and full diagnostic and battery health checks. Service B adds the pollen filter, air filter and fuel filter. Mercedes alternates between the two, and your car shows which one is due on the dashboard.
How much is a Mercedes service?
Service A starts from £149 and Service B from £350. Prices vary with the engine and the oil grade your Mercedes needs, and some cars will also be due brake fluid or other items. Call us with your registration for an exact price.
Do you change the oil in 7G-Tronic and 9G-Tronic gearboxes?
Yes. An automatic gearbox oil service starts from £299 and we recommend it about every 50,000 miles. Fresh fluid helps keep the shifts smooth. See our automatic gearbox oil service.
Do you service AMG models?
Yes. We look after the whole Mercedes range, from the A-Class and C-Class to the high-performance AMG models, using the right oil and parts for each engine.
Do you service Sprinter and Vito vans, and Sprinter motorhomes?
Yes. Sprinter and Vito vans are looked after through our commercial vehicle servicing, and Sprinter-based motorhomes through our motorhome and campervan servicing.
Where are you and which areas do you cover?
Our workshop is on Woolsbridge Industrial Estate, Three Legged Cross, Wimborne BH21 6SU. Mercedes owners come to us from Wimborne, Ferndown, Verwood, Ringwood, Bournemouth, Salisbury and across the New Forest.

As a nervous user of garages (due to past poor experiences), I was pleasantly surprised about the high level of service Rob Lang provided with our Mk6 Golf GTD, which wouldn't start, and was marooned on our driveway. He had it recovered to his premises within hours, and his technician diagnosed and solved several electrical problems, plus he gave it a full service and MOT (and valet). It now drives like when it was new and so will be reprieved. Rob then delivered the car to our house because we couldn't collect it for several days more. We can't thank him enough. His prices are fair and much better than a main dealer I suspect (and very importantly he kept us in the loop).

What a breath of fresh air! Having a problem with Audi RS6 suspension and when I called Rob Lang he booked me in same day to investigate. They identified the problem and also gave the car a good general inspection while it was up on the lift. Super friendly, very knowledgeable and I will be happy to get future routine servicing done by Langs from now on.
Tim LoganMarch 2026 · Google review
Amazing service, from start to finish the team were professional and explained everything. The knowledge and speed were second to none. Our car was fixed, serviced and unexpectedly cleaned within the timeframe quoted. They are not local to me but happy to travel for an excellent experience.
Martin OlliverMarch 2026 · Google review
Having just purchased an Iveco Daily van that had a few issues that needed to be rectified, I used an Iveco dealership who surprisingly did not completely fix the problems. I met Rob and his team of experienced engineers and was extremely impressed by their knowledge and expertise. They identified the cause of all the outstanding problems. This is a company who know what they are doing, and their customer service skills are top-notch.

Got my car fully serviced yesterday, and was pleased with the thorough detail and information the team gave me. Nice office, clean unit and overall welcoming experience.
Steven KingMarch 2026 · Google review
You cannot possibly go wrong by fully relying on their advice and guidance, with work that is second to none. Rob is knowledgeable and kind, with this pervading through all the staff. I was in a really tight spot with poor workmanship from another company; this was sorted out quickly and efficiently and everything made perfect. I cannot rate this company highly enough.
