Right, I believe I have the MY97 problem with the dump valve sounding like blowing over the top of a bottle between 2800 and 4000 rpm. I've been to the dealers and they claim to have changed the 'Feed Back valve'.. Do they mean the dump valve, or is this something else completly? I was just wondering before I go back again as I still have the same problem.

Cheers, Shaggy.

 

Sounds more like an internal part but I stand to be corrected.

Can you try someone elses you know works on their car and see if that cures it?

 

I could do I guess.. I just to convince a mate to remove his for an hour then.. Its worth a try..
