Sorry, interloper from the A3 forum here but this relates to an A4.
The bosses wife has an A4 Cab with the phone prep and MFSW but somethings not right.
The phone pairs up over bluetooth fine (LG chocolate) and she can answer incoming calls via pressing the left roller on the wheel but that's it.
Unlike my A3, pressing the "speak" button on the right does nothing at all, nor does the volume roller affect the volume of calls once in progress. The mode button to the left also does nothing at all.
This doesn't seem right - have Audi screwed up the coding on her car? If the car wasn't coded for the MFSW then sure the left roller press wouldn't work either, yet it does. Rather confused here - anyone got any ideas?
