Im getting the APR chipping done to my 2003 A4 Quattro and the guy told me that he thought the 2003 and newer A4's already have th 710 N DV installed on them, not the plain 710 . I have been reading that if you chip the 1.8T that you need to upgrade the DV to at least the 710 N (found in the TT's). Someone please let me know.

 

i dont know about that cause i know of some ultra sports that have upgraded their DVs to 710N
its like 30 bucks, its not that bad
