loss of power
« on: July 30, 2011, 07:47:48 pm »
hello people, i have recently noticed my mk5 gti is not moving like it normally does, what i seem to have discovered is that when i put my foot down there is a prolonged hissing noise? normally when i release the pedal there would be a short hiss which is to do with the turbo which is normal but in this case now, as soon as i put my foot down it starts and does not stop untill i release........

anybody got any idea of what this could be ?

Could be the DV mate.

Mine was doing something similar - perhaps not as bad - and the problem was a split diagphram on the divertor valve, a lot of people have upgraded to the rev 'd' which is a piston type so far superior......

It's around £40ish for the latest D version and you can fit it yourself (easier if you have an ed 30).   :smiley:

If it has the old diagphram type then I would change it anyway (which I think mkV's do), the new rev 'D' type is pretty much indestructable.  :happy2:

I had the old diaphram one on my Ed30. There was nothing wrong with it but i changed it for the D revision one as a matter of course.

10 min job on the Ed30. Slightly more difficult on the standard GTi.

Mine had a massive gash in the side. Made a big difference changing it for the D version  :grin:

^^ OEM part from dealer 40ish plus VAT, IIRC.

Part number 06H 145 710 D, although I was told at the dealer 06H 147 710 G was a piston-type valve too. :happy2:
