kelvin6 Posted December 6, 2012 Report Share Posted December 6, 2012 Hi there. Highly appreciated if someone can help. I got a 2008 Audi TT FWD TSFI 2.0 AUTO(DSG) When the car is steady, just release the brake and let the car go slowly (AUTOMATIC). (Not accelerator is required). You will hear something "knock , knock and slight vibration for 1-2 second. not very loud , but getting louder than before. no problem at all when accelerator is depress. Any idea. will it hurt the car or something needs to be replace? Many thanks! Link to comment Share on other sites More sharing options...

Thanks! Thanks Shao Hi although these do have a wee DMF......this sounds like its not the case at all. It sounds like the Mechatronics or dual clutch is playing up. More likely a mechatronics but some prematur wear may also have occurred on the dual multi plate wet clutch!!!! Ive replaced both mechatronics and clutches.......mechatronics do suffer from software issues up to a certain build. Clutches are a wear/tear replacement item but can often give jip due to a shafted mechatronics,but more often than not just judder or have really harsh up and downshift..........hope this sheds some light....contact me for more info.......Tidy Link to comment Share on other sites More sharing options...
