Is it my wastegate I can hear

[JamesA3]

when I lift of the throttle I can hear a very quite woosh noise which I have heard on other cars and was told its the wastegate is this correct?

 

[Mike.M]

Its the DV when you let off the throttle pedal

 

[JamesA3]

thats what it sounds like but I haven't fitted a DV, do they come as standard on 1.8T's

 

[Grant]

All turbo cars have DVs!

 

[JamesA3]

are they recirculating then rather than atmospheric?

 

[tennisguy]

Yes it is recirculate. If it is atmospheric (some of them are from aftermarket), then your car will lose power.

 

[Grant]

Audi's have recirculating valves. DV in this case meaning Diverter Valve rather than Dump Valve.

A couple of people on here are running asmospheric dump valves although it has been argued that it is not good for the car and therefore not recommended!

I only went to use "Mobil 1" engine oil as it was recommended by Forge to service their DV's.

Will get some of the grease you guys mentioned and give that a try at the weekend...................cheers!

Mike, the actual service instructions from Forge specify Mobil 1 Grease, which is either a typo by them or there is actually a Mobil 1 grease, but I don't know of one without looking on the web.

on my old S3, you could hear the air being released by the DV back into the airbox a lot more than the standard S3...

This was due to when the garage replaced my wing and them not doing a proper job by refitting the sound proofing on the inner wing! /ubbthreads/images/graemlins/mad.gif

Had a look on the Mobil 1 site - indeed they do do a Mobil 1 Synthetic Universal Grease..

WAK on the TT forums has some of this Mobil 1 grease in tubes for sale.

NOT cheap mind you. He could only source it from US and got stung by vat/customs.
