audi s3, lost boost

[malcolm30029085]

hi i got a 1999 audi s3 and when i bought it, it ran fine. but lately the turbo noise has become really loud ( like a split pipe) and when i change gear it dumps like i have a dump valve( and i havent!). also along with all thiss it has lost all its boost! any1 no?

Standard plastic diverter valve worn out - replace with an all metal one

It's a straight swap. No ECU jiggery-pokery required

The majority of people who upgrade their valves use ones from Forge Motorsport

Either the Bailey or the Forge. I went for the Forge (DV007P IIRC ). Give it a clean & re-grease once every 6 months or so and it's a happy chap.
