Hi fellow Audi fans. I have a problem with the telephone module in my 2009 A4. This causes the MMI to be slow to start when I start the car, I actually have to wait a few seconds and then hit the power button to get MMI, and thus the radio, to turn on. The dealer said it is bad and needs to be replaced. They have quoted me ~$1000 to do this. Is this any easy item to replace and if so, where can a replacement be found. If not, do I have any alternatives as to 3rd party replacements?
