Various warning lights on dash but cannot find fault!

    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

    These cars are electronically very complex, and as a result if there are any battery issues, it can cause a wide range of different, seemingly unrelated fault codes. Also one isolated fault can cause a cascade of different faults.

    Do you have access to VCDS to run a scan and see what the actual fault codes are? Some of the ones you describe can only be reset using a diagnostic tool like VCDS (Other tools are available)

    I would try and get a full scan of the fault codes if possible, and if nothing obvious shows, get an independent garage to run a battery test and see what the results are.
