Will it fit my Mercedes C Class W204?
Diesel only. Match the engine code — plug length/voltage differs between 1.6 and 2.0 TDI.
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 glow plugs needs replacing
- Hard starting when cold
- Glow-plug warning light
- White smoke on cold start
- Rough idle until warm
Fitting it yourself
Accessible on most TDI engines but seized plugs can shear — go slow, use penetrating oil.
Torque: Typically 10–15 Nm — over-tightening snaps them.
