Used Mercedes-Benz E-Class Water Pump

This depends heavily on the engine code, because the W212 E-Class ran from 2009 to 2016 with a facelift in 2013 that brought updates to several mechanical components including ancillary parts like the water pump on some engines. If both cars share the same engine code, fitment is possible, but because some mountings and ancillary details changed around the 2013 facelift boundary, you should confirm directly with the breaker against both registrations before buying.

The W211 ran from 2002 to 2009 and the W212 from 2009 to 2016, and these are distinct generations with different engine families, so a like-for-like swap is very unlikely even if the fuel type and displacement appear the same. The engine code is the definitive check here — give the breaker both engine codes and they will be able to tell you straight away whether the part crosses that generation boundary.

All Mercedes-Benz E-Class petrol and diesel engines across every generation — W210, W211, W212, and W213 — use a water pump as part of the cooling system, so yes, your car has one. Some later engines supplement the mechanical water pump with an electric auxiliary pump as well, so depending on your engine code there may be more than one pump to consider — worth confirming with the breaker which one you actually need.

No — AMG Line, SE, and Avantgarde are trim levels that relate to cosmetic and equipment differences, and they have no bearing on which water pump is fitted. What actually determines the correct pump is the engine code, which will be the same across all trim levels sharing that engine regardless of badge. Focus on the engine code from your V5 or a VIN check and ignore the trim name entirely when searching.

Body style makes no difference to water pump fitment — the pump is determined entirely by the engine code, not whether the car is a saloon, estate, coupe, or cabriolet. A W212 E250 CDI estate and a W212 E250 CDI saloon with the same engine code will use the same water pump. Just confirm the engine code with your breaker and body style can be ignored completely.

Yes, diesel and petrol engines are entirely different units and will have different water pumps, even within the same model year and generation. The engine code makes this clear — for example, a 651 diesel engine and a 271 petrol engine are completely separate, and parts are not interchangeable between them. Always give the breaker your exact engine code rather than just saying 'diesel' or 'petrol', as there are multiple diesel and petrol options within each E-Class generation.
