Mercedes-Benz CLS Fuel Filter Replacement Parts

It depends on your engine type. Petrol CLS models (such as the CLS 350, CLS 500, and CLS 55/63 AMG) have their fuel filter integrated into the fuel pump assembly inside the tank, meaning it is not a serviceable external filter in the traditional sense and is rarely replaced as a standalone used part. Diesel CLS models (CLS 220d, CLS 250d, CLS 350d, and the older CDI variants) do have a separate, accessible fuel filter that can be replaced, so if you have a diesel you are in the right place.

No, these are different generations with different engine families and filter housings, so a C219 filter will not cross over to a C218. The C219 used older CDI units (e.g. OM642, OM648) while the C218 moved to revised BlueTEC and later OM651/OM642 configurations, and the filter specifications differ accordingly. Always match by engine code first — provide your engine code and registration to the breaker so they can confirm the correct part.

The C218 received a facelift around 2014, primarily covering styling and interior updates rather than major engine changes. For most diesel engine codes the fuel filter specification carried over, but ancillary mounting arrangements and associated housing components can change mid-production, so confirm with the breaker against your registration to be sure the part from a pre-facelift or post-facelift donor is suitable for your car.

Trim level makes no difference to fuel filter fitment on the CLS — AMG Line, Sport, and standard variants all share the same filter if the engine code matches. The engine code is what determines the correct filter, not the badge or interior specification. Give the breaker your engine code and they will match the part correctly.

The OM642 engine was used across several Mercedes models, and in many cases the fuel filter is common across platforms sharing that engine code, making a filter from an E-Class W211/W212 or ML/GL potentially compatible. However, bracket fittings and housing details can vary by application, so route this question to the breaker and give them both the engine code (OM642) and your CLS registration so they can verify before supplying the part.

Petrol CLS models do not use a separately serviceable external fuel filter; the filtration element sits inside the fuel tank as part of the pump unit and is not routinely stocked or sold as a standalone used part by breakers. If you are experiencing fuel delivery problems on a petrol CLS, what you most likely need is the complete in-tank fuel pump assembly rather than a filter on its own. Search for a used fuel pump assembly and quote your engine code to the breaker to get the right unit.
