Have had all these problems lately especially since I just put a chip in. Thought the problem was the socket (loose). Hardwired it in, still have problems. The lights will go on split second, the trip odometer will reset, but headlights, aircon remain on, car does not stop. then it returns to normal. Happens during WOT. Also, sometimes the fuel gauge is all over the place and the RPM gauge and SPEEDO stop working during WOT. Any ideas. Planning to have it checked on the VAG this week. Tks.
