Thanks Steve Auto spark came back last night to say they sourced the problem to the rear comfort control module .
Im not convinced as they have had the car 2 months . I just hope its sorted .
What does the comfort control module do ?
of course i will know in a few days if its fixed ,i will update the post
Can someone offer a solution i purchased the 2013 Audi A6 Avant 2.0 litre diesel auto in may 2021 i love the car except its been with dealer for 2 months .
They say its a bcm module then a gateway module then a ccm module ? Shot gun diagnoses . I appreciate its not easy !
the above title is a link to exactly same faults
