Hi Guys,

I have got a strange problem, installed a brand new control module for AUdi
A8 2004, coded it good, no warnings on dash...after 1 hour I just ran an outuput test from VAG COM for the ABS, and suddenly ABS warning started to blink and there was no communication with ABS, I switched igntion Off/On and the comm was back, but this time there was a fault code in it saying, 000013 control unit defective.....how do i get rid of this code..its just stuck there...any ideas from experts..

 

Make sure the module in connected correctly and make sure the pins on the connector aren't bent. If thats not it check the part number on the module and compare it to your old one. If they are the same have the dealer run a coding procedure on it.
