Hi All,I am hoping someone can help, I have a 2012 A3 S-Line which I have just fitted a Witter towbar kit to along with an aftermarket universal bypass relay wiring kit. Followed all the instructions which were pretty straight forward. However, once I had completed the install, I then turned the ignition on only to find a number of faults inc stabilisation fault, air bag fault and power steering fault. Can anyone advise on what this might be and do I need to get it Audi to have these reset?ThanksPaul
