Hi,

Recently had the petrol pump and filter changed on my W215 CL600. Before that it was noisy, with a kind of whine and cold starting was a little jerky.

Everything now is smooth ........... apart from the same noise. Took it back to the Merc dealer who did the work and they were very helpful, but saying that this can and does happen on the V12s and V8s. They said the pump is working hard, hence the noise.

Anyone else have/had a noisy fuel pump and did you resolve it, please?
