The stock BOSCH valve is more than capable..

From what i have heard and read if you chip the Polo the stock DV wont last the tests of time and that it would be a good idea to change it.

They don't last forever but it is time more than boost that causes std DVs to fail. Often they have gone and you wouldn't know without looking.

Ive never had one fail on me but surely you would be able to tell something with how the car reacts. And maybe some of these good beople just wanna hear a sound from it.

I reckon that it would get laggy during gearchanges, if the boost isn't released the turbo would start stalling. I don't recall seeing any codes getting thrown on cars I found with bad ones.

So you are saying you would notice??? I thought you would and not only would it get laggy but it wouldnt do your turbo any good not having anywhere for the pressure to be released to. Gavin are you a mechanic.

Yeah it looks a bit contradictory now I read it again but I doubt 'man on the street' would recognise that the car was different. I have taken a few duffers apart and the diaphragm was only partially split. So I guess that the DV would fail over time and get progressively worse. The check light hasn't come on when I have found bad DVs.

It is bad for the turbo but if the car was still having dealer services they should catch the fact it has gone during a roadtest. I think it would take some rough treatment over a period of time for cause significant damage.

I am an Avionics Engineer for a day job but I am pretty well read on VWs in general as I run an A3 turbo with FMIC, 3 inch turbo back system. I have an 04 turbo and ancilliaries in the garage awaiting a few free days.
