Cheap Mercedes-Benz SLK Oil Pump

Yes, all SLK variants have an oil pump — it is a fundamental engine component present on every petrol and diesel engine fitted to the SLK across all three generations. Used examples are regularly available from breakers, but the correct pump is determined almost entirely by engine code rather than the model year or trim level. Locate your engine code from your V5C or a VIN check before requesting quotes, as this is the single most useful detail you can supply to a breaker.

The R170 ran from 1996 to 2004 and the R171 from 2004 to 2011, and these are distinct generations with different engine families, so an oil pump from an R170 is very unlikely to cross over to an R171. Engine codes changed significantly between the two generations, meaning the pump internals, mounting points, and pick-up geometry will typically differ. Always confirm fitment against your specific engine code with the breaker rather than assuming generation-to-generation compatibility.

The R171 ended in 2011 and the R172 launched the same year, continuing to 2016, but once again the engine family changed across this generation boundary. Some engine codes were carried over in revised form, so whether a pump crosses this boundary depends entirely on matching engine codes between the donor and recipient vehicle. Give the breaker both engine codes and ask them to confirm before purchasing.

The trim or badge designation reflects the engine fitted, so in practice it is the engine code underneath that badge that determines oil pump fitment, not the trim name itself. An SLK 200 and an SLK 250 may carry different engines with different pumps, while two SLKs wearing the same badge but built in different years could also differ if the engine was revised mid-production. Use your engine code as the definitive reference and confirm with the breaker against your registration.

No — diesel and petrol engines are entirely different units with different oil pumps, so a pump from a diesel SLK will not fit a petrol SLK and vice versa. The SLK range was predominantly petrol, but fuel type is still worth stating clearly when contacting a breaker to avoid any ambiguity. Confirm your fuel type and engine code together when requesting a quote.

The oil pump is driven by and mounted to the engine, not the gearbox, so in most cases gearbox type does not directly affect which pump you need. However, engine code remains the primary guide, and if any ancillary mounting or oil routing differs between gearbox variants of the same engine, this is something to confirm with the breaker against your specific registration rather than assume.
