Afternoon! I have an AUM 1.8t, the turbo seems to make a loud whistle like its leaking but it boosts fine, it only does this underload too, is this normal?
Also 3rd and 4th gear the boost isnt as strong, is that normal?
Thanks peeps
How you people doing? This site has some extensive knowledge in which I am going to reap the benefits!
Totally standard 1.8t and not a clue what to do first!
