2004 Audi S4 - Page 8 Questions & Answers
How do I reset the anti theft on my 2003 Audi A4 quattro? My car won't start!
One of the simplest ways to do this is to lock all the doors manually if you can, stand outside the car with your key in hand. Insert the key into the driver door key slot and turn it to Lock, Lock, Unlock, Unlock. That should tell the vehicle that it is supposed to turn off the anti theft. This can happen whenever the battery dies or looses power for whatever reason. It also happens frequently when someone locks their keys in their car and a towman or locksmith opens their door for them. Those professionals should have done the reset as part of their process though.
2003 Audi A4 Quattro. How do I bypass the anti theft system on my vehicle?
Very fine German engineering, you can't. The anti theft system is there to stop exactly what you are trying to do. You can't get around the anti-theft module and it connection to the ECM (a mini computer and a big computer protecting your vehicle from thieving ne'er do wells!). You have to fix what is wrong, not find a way around it.
Mobile auto electrician, alarm installer or dealership to diagnose with a $5,000 pro grade scan tool computer and fix.
Or perhaps, it just needs resetting? Did you disconnect the battery. We need the whole story.
