Diverter Valve shot?

[Norfolk Ollie]

Ollie, if you have K04, IE Edition 30/Pirelli (I haven't read thread) then swap out is 10 min job, piece of piss mate.
If you're normal GTI (K03) then more involved but not hard; at all.  After sorting location (different for each) it's 3 Allen bolts and a loom plug 

Cheers Scottymon  I might as well let them do it I reckon as they check it beforehand anyway. It's a standard GTI- the only thing that was different today was I had the front windows open so maybe I just heard the whistling where as I couldn't before? I took it out just now and it seems to be accelerating fine now so maybe I was convincing myself about the 'thrust'? I don't know- it was a long day working outside in the sun...

Thanks Rich- I've only had the car a short while so forgive me if my questions seem a tad ignorant. I don't have the luxury of time to get the DV or PCV checked/replaced so surely I've got nothing really to lose by going?
Cheers, Ollie 

Sort your car out first.

Yes Niki will have the PCV and DV checked over. I took my GTI to them for a smoke test and they found it was the Forge DV causing a boost leak. They replaced it with a Rev G (which they seem to keep in stock) for £50.

This is from their website:

"R-Tech can supply and install a new G DV to your car for just £45 during the remapping session. As part of the remap service we will check the DV free of charge before starting to tune the car so don’t worry too  much about having to replace or checking the DV yourself we will make sure all is ok before tuning.".
