Post by: jcm76 on May 22, 2010, 05:37:43 pm

Hi guys, thought I maybe loosing boost and after a trip to my local garage with vagcom they have confirmed his. I have booked it in with them for next week, however is there anything I can check and do myself? Please keep it simple, I try not to lift the bonnet to often!

Loud(er) whistling or wooshing when the turbo comes on boost would point towards a boost leak.

So, I'm guessing I have a split hose or dv issue somewhere, can anyone give me a few pointers on where to start looking?

it'll be a split dv for sure. I had the same issue and sorted it by getting the new OEM dv from the dealer. It was a pain to replace due to lack of access, but still better than paying a fortune to a garage to replace!
