I bought my 2002 A4 1.8TQ from someone in Kingston who had it chppied at Chris Tapp in Ottawa... it runs GREAT and the performance is excellent as I am coming from the Chevy ol'-boy 350 class I did not want the wimpyness of the 4 cylinders!

I have a problem though with a P0411 code that shows up now-and-again for now reason and more so in extreme cold wether.
The dealer (Owasco) blames the chip, and I think is not it!

I am getting the Professional VAG-COM and am going to get to the bottom of this.

I feel chipping is the way to go!
