audi a3 ACC issue

[immydoug]

hello guys, 

 

need some help

 

i have an audi A3 2013 with adaptive cruise control and recently i changed the wheels and alloys on the car. 

nothing crazy so now i have the s line wheels and all of a sudden 2 days later my ACC stopped working. took it to audi and they were useless charged me £120 an hour and they said they checked the  wiring to the ACC unit and the wiring is not the problem.

all of a sudden it occured to me that it could be the wheels and alloys that might  be the issue. 

has anyone else had this before? help much appreciated
