Mercedes-Benz CLS Fuel Pump Replacement Parts

The CLS W219 ran from 2004 to 2010, and the current CLS W218 launched in 2011, so a 2008 and a 2012 car are from entirely different generations with different engines and fuel system designs. A pump from the W219 is very unlikely to suit a W218, even if the engine displacement sounds similar. Always confirm the engine code from your V5 or a VIN check and give it to the breaker before agreeing a sale.

These are two distinct generations — the W219 covered 2004–2010 and the W218 ran from 2011 to 2018 — and they do not share the same fuel pump assemblies. The critical detail to match is the engine code, not the generation badge, as different engine variants within each generation can use different pump specifications. Confirm your engine code with the breaker and they can cross-reference it against the donor vehicle.

Trim level as a name does not affect fuel pump fitment — what actually matters is the engine code underneath that badge, plus whether the car is petrol or diesel. A CLS 250 CDI and a CLS 350 BlueTEC carry different engines and will need different pumps, so those differences are real, but they are driven by the engine code rather than the trim name itself. Give your engine code and fuel type to the breaker rather than just the trim badge.

Yes, every CLS variant has a fuel pump, because they all run petrol or diesel internal combustion engines that require pressurised fuel delivery. The design and specification of the pump does vary depending on whether the car is petrol or diesel and on the specific engine code fitted, so a like-for-like match on engine code is essential when sourcing a used unit.

The gearbox type — automatic or manual — can influence fuel system ancillaries on some vehicles, so it is worth mentioning to the breaker alongside your engine code and fuel type. The engine code remains the most important detail for matching the pump itself, but giving the breaker the full picture including gearbox type helps them rule out any mid-production variation on the donor car.

The W218 received a facelift in 2014, and while the core engines carried over, there can be ancillary or mounting changes at that boundary that affect whether parts interchange directly. The engine code is the key detail here — if the donor and your car share the same engine code, fitment is more likely, but crossing the facelift year boundary means you should confirm compatibility with the breaker against your exact registration before buying.
