Evening, took my a4 b6 20v turbo 190 into a local reputable vag specialist for a chain tensioner replacement as it was leaking oil and rattling on start up, also turns out one of the guides had broken up. He's replaced the tensioner, gaskets and all timing gear/water pump as requested with parts I've supplied (mixture of genuine and non gen but OE quality items) he's started up but I still have a rattle from cold and now it's running like a pig. Any ideas? At the moment I'm thinking possible oil pressure/pump issues. Any help would be great!

Hi there had this when I did my tensioner on a4 2.0fsi the cam locking tool allows the exhaust cam to turn slightly and you get the chain one notch out. Check the chain I had to turn the right hand cam one tooth anti clockwise as looking from the front. Hth
