Hi and hope someone can help.

I have had about 5 or 6 warning lights come up on the dash at the same time. These include handbrake failure, eps error, rear spoiler problem, headlight sensor problem, and some others...

Originally the car was viewed by Audi dealer who diagnosed the fault as the Abs controll unit which under external warrantt was changed for a second hand unit elsewhere this cleared the issue for around 4 months which then returned.

I then took it to a audi specialist who felt it should have a had a brand new Abs unit and coding but guess what.... its happened again!!!

Please help on suggestions for what to do or try next either physically or contact wise.

The car is an audi a7 2013 tdi not s line
