Hopefully someone can answer my question? On my 2011 TT 2.0 tfsi quattro, the previous owner had it stage 2 revo tuned with a Cobra centre and rear section exhaust. After having work done on the haldex box, the garage informed me that my car would not pass the emissions test due to the removal of the CAT. I have the original centre section exhaust, just need to add the lambda sensors. My question is, will the original centre section fit back on, considering the remap, will i encounter any problems, error codes etc? Thanks in advance Gary

Hi everyone, my first post on here after taking purchase of my 2011 TT tfsi quattro with a revo stage 2 and stage 1 on the s tronic box. After enjoying driving my TT for a matter of weeks (bought from a private owner) I have broke it. On driving home from a lovely drive I started hearing some strange noises and the car wanting to pull up sharply. This happened again before I limped home. On getting home I looked under the car to see oil running out the rear section which I assume to be the haldex box. I have put the car into an Audi specialist for them to sort it. The big question is, what cost can I expect? Thanks for help in advance. Gary
