Title: Weak Boost on my gti and chirping sound from turbo. HELP
Post by: saunders400 on May 27, 2015, 09:18:44 pm

I have been experiencing weak boost on my gti recently.  Also at times I get a sort of chirping noise coming from the turbo when I accelerate at low revs (2000-3000) this then goes when up in higher rev range.
I changed the DV valve last year and have done the pcv test and all fine there.

Any ideas what this could be?
Thanks

I had the same issue a while back. I did get boost back when I changed the DV valve though but still left with a faint whistling sound when accelerating. German Motor Company in Southfields London said its the turbo and nothing to worry about.
I do have full boost though.... so different from your problem.
