hi newbie here good to join the club  just bought a audi a4 b5 1.8 tqs k03 turbo has the dreaded turbo rattle on over run and not getting any boost thinkin its the penny valve away is there any way of adjusting the wastegate via rod to get by some time 
or just get another turbo k04 015 one thanks planning on modifying this car seen turbos cheap on eBay but heard the horror story on these any help would be much appreciated
