Mercedes E-Class service and repair specialist

Is this page for my E-Class?

The Mercedes-Benz E-Class, including the W213 and the W214, does chauffeur work, private hire and everyday family duty. We service, diagnose and repair it at our Welwyn Garden City centre. Some of the points below also apply to the earlier E-Class (212). For private hire and chauffeur use, see our PCO and chauffeur servicing page.

How often should an E-Class be serviced?

Follow the service interval display. In the E-Class owner’s manual, Mercedes calls it ASSYST PLUS and says it shows the time or distance left before the next service. It can bring the service forward after mainly short-distance driving, long idling, frequent cold starts and frequently interrupted diesel particulate filter regeneration.

Mercedes also calls the display only an aid, and treats regular city driving with frequent intermediate stops as arduous use that needs more frequent oil and filter changes. Private hire work in town can fit that description, so ask us whether your oil and filter should be changed sooner. Our Service A and Service B page explains each service.

We also add the service to the car’s digital service record.

Which engine oil goes in an E-Class?

Oil that meets the Mercedes-Benz specification sheet listed for the engine. Mercedes publishes the sheets engine by engine. If your E-Class has the OM654 diesel and is not a plug-in, Mercedes lists sheets 229.52, 229.61, 229.71 and 229.72, but not 229.51.

The binding specification is the one in the vehicle’s own manual, and Mercedes warns that low-viscosity oils in an engine not cleared for them can cause damage.

Does the automatic gearbox need servicing?

Yes. Mercedes workshop information lists the 9G-Tronic (725.0) for the E-Class 212 and 213, and the current fluid sheet for that gearbox is 236.17. Some 212 cars have the 7G-Tronic (722.9) instead, which takes a different fluid, so we confirm the gearbox from the registration. We carry out the gearbox oil and filter service in-house and set the fluid level the way Mercedes specifies. The interval varies, so we work from your car’s own schedule. See our Mercedes gearbox service page.

What if the AdBlue warning comes on?

The E-Class owner’s manual describes the sequence: an AdBlue system fault message with the engine warning light, then a speed restriction and a countdown shown as “Start not poss. in” followed by a distance, then an engine that cannot be restarted.

We check the recall status and software level first, then test the NOx sensors, dosing, pump and heater, and replace only the part the tests prove faulty. We repair AdBlue and emissions systems; we never remove or disable them. See our AdBlue fault page.

Do you repair E-Class air suspension?

Yes, where it is fitted: some E-Class cars have air suspension or AIR BODY CONTROL and others do not. Typical signs are the car sitting low after standing, or a suspension warning. On the 213, Mercedes says a message limiting the car to 50 mph can come from the ride-height calibration or tension in the rear axle rather than a leak, so we measure and leak-test before quoting. See our air suspension page.

What do the battery warnings mean?

• Auxiliary battery malfunction. On the 213, this small battery backs up the gearbox park function. We test the main battery first. See our auxiliary battery page.
• 48V battery warnings. Mercedes’ guidance on 48V mild-hybrid faults covers the E-Class 213 and 238. Each stored fault has a different remedy, so we read it before anything is replaced. See our 48V battery page.

Which recalls should an E-Class owner check?

Check your car on gov.uk: whether a recall applies depends on the individual vehicle. DVSA’s records for the E-Class include:

• Emissions software and NOx sensors: R/2019/304, R/2019/307, R/2020/231 and R/2020/243, Mercedes car recalls that include E-Class built from 2011 to 2019.
• Timing chain: R/2022/116, for some C-Class and E-Class built from February 2016 to February 2019.
• Coolant pump: R/2021/438, for some diesel models, including the E-Class, built from April 2017 to October 2021.
• Turbo oil feed pipe: R/2020/048, for some E-Class built from May 2018 to May 2019.

Recall work is done by the manufacturer’s network, not by us.

Can you MOT my E-Class?

Yes, in our own Class 4 MOT bay. Warning lights and leaks are worth having diagnosed before the test. An E-Class licensed by TfL needs two MOTs in each annual licence once it is more than 12 months from manufacture; our PCO pre-inspection check page explains the timing.

Do you work on plug-in hybrid E-Class models?

Yes. Servicing and repairs on plug-in hybrid E-Class models are carried out by technicians qualified to work on electric and hybrid vehicles.
