Hi,
Any help/suggestions with this would be much appreciated. I bought an S6 in a private sale a few days ago and since then random fault codes have been appearing when I start the car but then disappear when the car is turned off and then back on again. The first issue was a fault with the start/stop- a message appeared and the car refused to start. I turned the start/stop off and tried again and the car started. I turned the car off and then back on again with start/stop engaged and it was fine with no messages.
The next issue, later the same day, the display showed a fault with adaptive lights- again this code disappeared when I turned the car off and on again. Later the same day,another issue. This time, adaptive cruise was unavailable with the message "ACC and Audi braking guard not available". I turned the car off and back on and this issue also disappeared.
I am booking the car in for a diagnostic check with my local dealership asap but was wondering if anyone has any ideas on what the problem could be? I'm wondering if it could have been caused by out of date software maybe?
I'm also wondering where I stand with the previous owner who assured me that there were no faults when I bought it from him
Thanks everyone for reading this!
