I have a 2003 A6 3.0L and something happened the other day because normally the doors lock after 15KM but for some reason the doors do not lock anymore (on their own) Can anyone help me reset the mechanism or tell me what i need to do? or Check?

 

That has to do with the coding of the comfort control module. US spec cars don't do that (or isn't coded to) so i wouldn't know the coding off hand. Check the ross tech web site www.ross-tech.com to see what the comfort control module has to be coded to. Also check module 46 for fault codes using your VAG COM. If you don't have a vag com you need to buy one before we can proceed.
