Will it fit my Mercedes C Class W204?

Diesel common-rail injectors are usually coded to the specific vehicle/ECU and often need programming after fitting — not always a straight swap.

Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.

Signs your Mercedes C Class W204 fuel injector needs replacing

Misfire on one cylinder
Rough idle, hard starting
Poor economy, smoke on diesel
Injector fault code

Fitting it yourself

Accessible on most engines but diesel injectors can seize in the head; petrol injectors are usually simpler. Diesel jobs often need specialist coding after fitting.
