02 c32 engine ticking noise
 
Hi,

Need some advice. I recently noticed a loud tapping noise which was quite audible under light acceleration but could also be heard when stationary (but noy as loud)

The noise would work with the revs and not engine speed.

Took the car to the dealer, they had it for a month!!!!:eek: and changed the tappets. All seemed well but after a few days the noise has come back ...its not as loud but seems to be more of a ticking noise now (like ticker tape stuck in a fan)

Needless to say, I will have to call my dealer again today to get it booked in but has anybody had the same problem that wasnt tappets?

I think my dealer may need some pointers.

Many Thanks for any comments

Sorry to hear that. That doesn't sound too good at all. Well, my first question is whether you had to pay for the first set of repairs or were they part of some warranty service. Did they show you the old items they replaced?

Thanks for the reply.

Luckily I had third party Warranty...but had to pay 40%Labour costs which was £300. It would have cost me £1600 without it (touch!)

Anways, I am going back saturday morning for a road test so we can both have a listen before diagnostics.

They tried the Purge valve and it wasnt that.

I am not sure where we go with this really!?

Fuel pump located under the rear seat. Noise is coming from the transfer of fuel from one side of tank to the other. This is what the dealership diagnosed mine.
Fuel pump replaced, purge valve replaced, noise still there. Apparently this is normal operation common on C32, C320 up to MY 2004.

does the noise comes from the driver side in the engine bay if so .. its the Purge Valve they need to replace it with the newer version ...it has like more rubber cushion so to make the tapping noise less or some crap like that.

I also have a ticking noise on the driver's side engine compartment. It seems to be coming from some sort of valve with some plastic lines going to it. Funny, b/c I thought it was a lifter or cam at first, because it sounded real loud the first time I heard it parked against a wall at my local drive-up ATM. There is also a plug going to it.
It sounds like a dampened rubber metalic clicking.

Interesting.....my place disconected the charger and it still made the noise so its not that.

What I will say, they did change the tappets and the noise is less audible but it is still there. There must be something around that area thats the culprit!!!!
