Audi A6 2012 fault codes ...sometimes ??

[Steve Lincs]

Hi everyone ,
A6 2012 S-Line 2.0 diesel ...my problem is this : sometimes and normally only when car is full ( full boot and 3 people in back ) I get fault codes pop up even though car drives fine! ABS fault, handbrake fault, car to steep for handbrake to work warning , and because of these sometimes the car then goes into some kind of limp mode ( AC stops working ). This happened last year on summer holidays and since then everything has been fine ( no fault codes on dash) but loaded car drove through Germany with 3 people in the back and up pop those fault codes again ? I stop the car start again and codes clear ? I forgot to add ...tyre pressure fault comes on also ! When I use the tyre pressure store / check that also seems to clear codes ? Just to note ....I use the car for work ( 120 miles round trip each day ) alone and have done 7000 miles with nothing coming on until my Christmas trip with car full ? Any advice would be gratefully received.

A full “global scan” fault code read, print and clear of all the vehicles system and then drive the car again until the problems reappear and then another full scan and print so the two results can be compared to see what has come back.
