RAF_S7said: Start with the electronics bay in the boot, should be on the left hand side behind the cover. Audi tend to have an orange fibre cable, inside some black tubing.

I got in the car the other evening, and the MMI screen didn't turn on. Holding the volume/power button didn't work. All of the buttons around the MMI controls didn't work. No bluetooth, radio, nada. I turned the car off and back on, still nothing. . 122 66 381 260 245 77 309 257 385
