No help but after mine was done everything was ok & as before other than the horrible rattle.I'm thinking they have missed something?.

Is it remapped?  REVO software??

Other than that you'll need to get it checked with VCDS.

Sounds like they may have disconnected the battery and the Map has reverted to stock.

Or they have slightly misaligned the intake cam and its losing power because it slightly open on the combustion stroke.

I think that would show up in VCDS which is why I suggested it.  You get a fault code something about correlation.
