My audi a3 8p 2.0tdi quattro just developed a scraping noise from inside the cab but it's like the pedal n throttle aren't in synced. Any ideas ppl PLEASE 

Hello John,

I’m not sure here whether you have 3 not connected, issues, or 3 separate issues. 

So difficult to advise without more in-depth meaningful detail, but:- 

Scraping noise - have you checked that any part of the undertrays etc has not become dislodged? 

Sticking throttle? - don’t know 

Throttle and acceleration out of sync. - again difficult, but worth Googling resetting the throttle position sensor. Not sure on your particular model, but it would be something like switching on ignition and pressing the accelerator pedal to the floor, and return 5 times within a specified time ( say 20 seconds). After the 5 x presses, wait for something like 20 sec. and fully press and return again, and switch off ignition. The above is from memory, so please Google and follow the procedure. 

Kind regards,

Gareth.
