Hi guyz
1. ok as you can tell by my title I have a few problems, first I have this issue with the engine when I turn it on it raves it self up then down the car shakes to much sometimes fills like its going to store, and it Almost dose,

2. the other problem accrued yesterday when I unlock the car ( remote central locking) it flashes as it should be on the unlock but when i lock the car it dose not flash just locks without me knowing if it locked or not...until manually checked.

3. by the way my full exhaust system needs change,...should i place a new sport calister converter? and could the exhaust cuz all this wreaking the engine behavior described above.

 

1 and 3 could be linked because any holes in the exhaust will cause RPM issues,

2, is normal but you can have the alarm programmed with VAG so should the horn or flash the indicators
