Hi Everyone. New member here - and not a mechanic. I have recently purchased a 2011 motorhome on a Fiat Ducato chassis - 2.3 MJD, with 23,000 miles. I noticed a 'buzzing' from the centre of the dashboard and traced the noise to the EGR control valve. My local garage confirmed that this was where the noise was coming from and said they could replace the EGR CV but that the noise could come back... Well as it was an expensive item and since the van is under warranty, I decided to have it changed. It was fine for a short while but now after just a couple of hundred miles, the noise is back. I have read that this can also be because of a problem with the throttle body. Just want to try and point my local garage in the right direction with this and try and get the problem fixed while I'm still in warranty from the dealer I bought it from. Thanks!

Dennis from Denmark.Hi, did you ever find out why the buzzing noise came back? Was it an original Fiat EGR valve that was put on or a non original? I have a similar model and experienced the same irritating noise and replaced the EGR valve with a non original and it was silent for 600 kilometers. Then the noise came back and it sounded even more worse than the old one. Replaced it once more with a second non original (another brand) and the same thing happened - the noise came back after 300 kilometers. Has anyone experienced that? I am thinking of replacing it this time with an original Fiat spare part but would love some feedback if others have experienced the same problem? Thanks.
