Mercedes service due? Service A or Service B, carried out to the letter of the schedule.
Based in Westerhope, Newcastle upon Tyne, we service Mercedes-Benz cars and vans to the ASSYST Service A and Service B schedule, using oil carrying the correct MB-Approval and quality parts.
Exacting work on cars built to exacting standards.
Call West Auto on 0191 271 1605 or enquire online to get booked in.
At West Auto, we keep things clear and practical from the start.
We work with Mercedes drivers across Newcastle, Westerhope, West Denton, Chapel House, Chapel Park, Newbiggin Hall, Lemington, Denton Burn and the surrounding areas, on cars and commercial vehicles alike.
If your Mercedes needs more than a service, you are already in the right place. Our garage services include servicing, diagnostics, repairs and MOTs.
Service A is the lighter of the two. Engine oil and filter, fluid level checks, tyre condition and pressures, a brake inspection and a reset of the service counter.
Service B covers everything in Service A, then adds the cabin dust filter and a brake fluid exchange, along with a more thorough inspection.
Your car works through A, then B, then A again, so the two alternate over the years. Additional items such as spark plugs, air filters and fuel filters fall due at their own intervals on top.
The display will tell you which is due. Read it out to us when you call and we will know exactly what your car needs.
That is why two identical cars can be due at very different points. A Sprinter doing long motorway runs and one doing short urban drops will reach a service at quite different mileages, and correctly so.
The system displays the service type due and the days or miles remaining. It is a good system, but it only works if the service is carried out properly and recorded correctly afterwards.
Two conditions apply: the manufacturer's schedule must be followed, and the parts and fluids used must meet the manufacturer's specification. That is how we service Mercedes-Benz.
You get a full invoice detailing the work carried out and the parts and fluids used. Keep those. They are your service record and your evidence if a warranty question ever arises.
This is not a technicality. An oil outside specification produces excess ash that accumulates in the DPF, and on modern diesels a blocked filter is a substantial bill.
There is a second reason it matters on Mercedes specifically. Because ASSYST extends intervals based on driving conditions, the oil in the engine has to be capable of going the distance. Fill it with something cheaper and the interval the car has calculated is no longer safe.
We check what your specific engine calls for before the car comes in.
Where many makers describe automatic gearbox oil as filled for life, Mercedes specifies an oil and filter service on most automatics at a defined interval. It is on the schedule, and it is skipped constantly.
The reason it gets skipped is that nothing feels wrong when it is due. The reason it matters is what happens when it is not done: harsh or delayed shifts, hunting between gears, and eventually a gearbox needing far more than an oil change.
If your Mercedes is past 40,000 miles and has never had one, it is worth asking about. See our gearbox servicing page.
A van off the road is lost income, so the emphasis shifts to keeping downtime short, catching wear before it becomes a breakdown, and being straight about what needs doing now versus what can wait for the next visit.
We service and maintain Sprinter, Vito and Citan, and work with fleet operators as well as owner-drivers. If you run several vehicles, call us and we can talk about scheduling them sensibly rather than reactively.
At West Auto, you get:
Give us your registration, mileage and whatever the service display is showing when you call. We will tell you which service your vehicle needs, what it covers, and what it will cost before you commit to anything.
We are based in Westerhope, Newcastle-upon-Tyne and are open Monday to Friday.

Your Local Independent Mercedes Garage in Westerhope, Newcastle
Mercedes-Benz builds cars to be maintained rather than neglected, and the engineering assumes it. Air suspension, complex automatic gearboxes and closely specified fluids all reward being looked after and get expensive when they are not.At West Auto, we keep things clear and practical from the start.
We work with Mercedes drivers across Newcastle, Westerhope, West Denton, Chapel House, Chapel Park, Newbiggin Hall, Lemington, Denton Burn and the surrounding areas, on cars and commercial vehicles alike.
If your Mercedes needs more than a service, you are already in the right place. Our garage services include servicing, diagnostics, repairs and MOTs.
Mercedes Service A and Service B
Mercedes-Benz alternates between two service types rather than repeating the same one each year.Service A is the lighter of the two. Engine oil and filter, fluid level checks, tyre condition and pressures, a brake inspection and a reset of the service counter.
Service B covers everything in Service A, then adds the cabin dust filter and a brake fluid exchange, along with a more thorough inspection.
Your car works through A, then B, then A again, so the two alternate over the years. Additional items such as spark plugs, air filters and fuel filters fall due at their own intervals on top.
The display will tell you which is due. Read it out to us when you call and we will know exactly what your car needs.
What ASSYST Is Telling You
Mercedes uses the Active Service System, or ASSYST, to work out when a service falls due. Rather than counting miles alone, it factors in journey length, engine load, operating temperature and how the vehicle is actually used.That is why two identical cars can be due at very different points. A Sprinter doing long motorway runs and one doing short urban drops will reach a service at quite different mileages, and correctly so.
The system displays the service type due and the days or miles remaining. It is a good system, but it only works if the service is carried out properly and recorded correctly afterwards.
Will Independent Servicing Affect Your Mercedes Warranty?
No. UK block exemption rules entitle you to have your vehicle serviced by an independent garage without affecting the manufacturer warranty.Two conditions apply: the manufacturer's schedule must be followed, and the parts and fluids used must meet the manufacturer's specification. That is how we service Mercedes-Benz.
You get a full invoice detailing the work carried out and the parts and fluids used. Keep those. They are your service record and your evidence if a warranty question ever arises.
MB-Approval Oils
Mercedes-Benz operates its own oil approval system, with specific MB-Approval numbers rather than a general viscosity grade. Different engines call for different approvals, and diesel models with a particulate filter need a low-ash oil to the correct standard.This is not a technicality. An oil outside specification produces excess ash that accumulates in the DPF, and on modern diesels a blocked filter is a substantial bill.
There is a second reason it matters on Mercedes specifically. Because ASSYST extends intervals based on driving conditions, the oil in the engine has to be capable of going the distance. Fill it with something cheaper and the interval the car has calculated is no longer safe.
We check what your specific engine calls for before the car comes in.
The Automatic Gearbox Service Everyone Forgets
This one is worth singling out, because Mercedes handles it differently from most manufacturers.Where many makers describe automatic gearbox oil as filled for life, Mercedes specifies an oil and filter service on most automatics at a defined interval. It is on the schedule, and it is skipped constantly.
The reason it gets skipped is that nothing feels wrong when it is due. The reason it matters is what happens when it is not done: harsh or delayed shifts, hunting between gears, and eventually a gearbox needing far more than an oil change.
If your Mercedes is past 40,000 miles and has never had one, it is worth asking about. See our gearbox servicing page.
What a Mercedes Service Includes
Depending on whether Service A or Service B is due, the work covers:- Engine oil and filter to the correct MB-Approval.
- Cabin dust filter on Service B.
- Brake fluid exchange on Service B.
- Air filter, when due.
- Fuel filter on diesels, when due.
- Spark plugs on petrols, when due.
- Brake pad, disc and wear sensor inspection.
- Tyre condition and pressures.
- Suspension and steering inspection.
- Coolant, screenwash and fluid levels.
- Lights, wipers and battery condition.
- Diagnostic scan for stored fault codes.
Mercedes-Specific Jobs Beyond the Service
Several items sit outside the A and B schedule and catch owners out:- Automatic gearbox oil and filter. On the schedule, widely skipped, and expensive to ignore.
- AIRMATIC air suspension. Air struts and compressors are known wear items on models fitted with it, and a sagging corner overnight is the usual first sign. See suspension repairs.
- AdBlue and BlueTEC. Modern Mercedes diesels run an SCR system with its own particular faults. See AdBlue repairs.
- 4MATIC fluids. Transfer box and differential oils on four-wheel-drive models, rarely mentioned and easily overlooked.
- Timing chains. Most modern Mercedes engines use a chain rather than a belt, and chain life depends heavily on regular oil changes at the correct specification.
- Brake fluid. Included in Service B, and worth confirming it has actually been done if you have inherited a patchy history.
Mercedes Vans and Fleet
Mercedes-Benz commercial vehicles are a large part of what we see, and they have a different set of priorities.A van off the road is lost income, so the emphasis shifts to keeping downtime short, catching wear before it becomes a breakdown, and being straight about what needs doing now versus what can wait for the next visit.
We service and maintain Sprinter, Vito and Citan, and work with fleet operators as well as owner-drivers. If you run several vehicles, call us and we can talk about scheduling them sensibly rather than reactively.

Mercedes Servicing FAQs
What is the difference between Mercedes Service A and Service B?
Service A is the lighter of the two, covering engine oil and filter, fluid levels, tyres, a brake inspection and a reset of the service counter. Service B covers everything in Service A plus the cabin dust filter and a brake fluid exchange, along with additional checks. They alternate, so your car works through A, then B, then A again.
What is ASSYST on a Mercedes?
ASSYST is the Active Service System, which calculates when a service is due based on how the vehicle is actually driven rather than a fixed mileage. It accounts for journey length, engine load and operating temperature, then displays the service type and the days or miles remaining.
Will independent servicing affect my Mercedes warranty?
No. UK block exemption rules entitle you to have your vehicle serviced by an independent garage without affecting the manufacturer warranty, provided the manufacturer schedule is followed and the parts and fluids meet specification. Keep the invoices as your service record.
Does a Mercedes automatic gearbox need an oil change?
Yes. Unlike many manufacturers, Mercedes specifies an automatic transmission oil and filter service at a defined interval on most models. It is one of the most commonly skipped jobs on the car, and skipping it shortens the life of an expensive gearbox.
Do you service Mercedes Sprinter and Vito vans?
Yes. We service Mercedes-Benz commercial vehicles alongside the car range, including Sprinter, Vito and Citan, and we work with fleet operators as well as individual owners.
