Second Hand Mercedes-Benz CLS ABS Pump

Yes, every CLS variant sold in the UK was fitted with ABS as standard, so an ABS pump (also called an ABS modulator or hydraulic control unit) does exist on this model across all generations and engine variants. The unit combines with the ESP/traction control system on all CLS models, so you are looking for the combined ABS/ESP hydraulic pump assembly rather than a standalone ABS-only unit.

These are distinct generations with different brake and ESP architectures, so the ABS pump is not a straightforward swap across the C219-to-C218 boundary. You should confirm exact compatibility with the breaker by providing your full registration, as the hydraulic units and control modules are matched to the generation. Never assume a C219 pump will plug straight into a C218 car without checking.

Yes, engine size can matter for the CLS because larger-engined variants such as the CLS 500 or CLS 55 AMG may use uprated brake hardware with a corresponding ABS pump calibrated for higher braking forces compared to a CLS 220d or CLS 350. When asking a breaker for a quote, always give your engine size and the part number from your existing unit if you can find it. This gives the breaker the best chance of matching the correct pump to your car.

It can matter, particularly if you have an AMG variant, as these cars often use larger brakes and a differently rated ABS/ESP hydraulic unit compared to standard diesel or petrol models. For non-AMG variants like the CLS 220d and CLS 350 within the same generation, there is a reasonable chance the pump is shared, but you should still confirm against your registration with the breaker rather than assume. Providing your VIN or registration plate is the safest approach.

Trim level names like Sport or AMG Line are largely cosmetic designations and do not in themselves change the ABS pump fitted, unlike the AMG performance variants which use genuinely different hardware. The pump is determined by your generation, engine, and whether your car has a full AMG powertrain, not by whether you have AMG Line badging or sport seats. Tell the breaker your registration and they can cross-reference the correct unit regardless of trim name.

The C218 generation ran from 2011 to 2018 with a facelift introduced in 2014, and while the underlying platform remained the same, it is possible that brake system calibration or software versions changed at the facelift point. Whether a pre-facelift pump crosses over cleanly to a post-facelift car is something you should confirm with the breaker using your registration, as module programming can be generation-specific even within the same body style. A good breaker will check the part number against your VIN before quoting.
