New 2002 A4 B6 owner
 

Hey guys,

New to the audi world, picked up my 2002 A4 B6 a few weeks ago and had some issues

Breaks were shot, rotors were just as bad, heater core was plugged and blowing cold air (not good for our winters), and recently just fixed N75 valve.....

For reasons unapparent to me.. the previous owner(or person who worked on it) bypassed N75 valve and went straight from
Wastegate -----> Turbo ... resulted in 3psi spike and 1psi hold...

anyways..

Reason im making topic... I cant seem to get a straight answer about an issue im having

Passenger door is a lemon, window does not work, mirror does not work, door does not lock...

some say the passenger door regulator, some say the CCM, some say door latch...

maybe if someone has another idea of something I could check or test without spending between 100 - 1000 on trial and error would be awesome...

thanks;
