I have a 2019 A6 2.0 diesel. About 2 month ago I got a light on the dash “driver system fault” was put on the computer advised to put DFP cleaner in. Seemed to sort the problem for a few weeks and then same light back on so Put more DPF cleaner in. On Friday the DPF light also came on and on Sunday I lost power, Revs to 250RPM. Took for good run 50miles and DPF light has now gone off (still have driver system fault) and still have no power 😔. Any help, advise or garage recommendations in the north east would be greatly appreciated.
