My 2005 A6 Quattro recently failed to start. At the dealer they upgraded the firmware for the entire system in order to fix the issue.

Since then....

My BT voice quality is very poor. Prior to that, I tried many different BT phones and they all worked flawlessly. All of them did not exhibit full seettings (antenna strength, phonebook, etc.) but did have really good voice quality over the BT link. These phones have always paired with the MMI system without any issues.

Since the update the call quality is so poor, I quite often turn of the phone's BT because I cannot communicate. The same phones, no new ones.

Taking the car back to the dealer they cannot find anything wrong.

Any Ideas ?

 

Did your car fail to start with the start button or the key switch?

You should talk to the service manager and tell him to the shop foreman involved, this will increase the chances of a fix

 

Thanks for the info.

Actually the shop foreman was involved in the fix attempt. Even the Service Manager was very involved.

The car failed to start with the keyswtich. I do not have the start button option. It seems to be starting up fine now, but the BT is still an issue. Quite frankly, it stinks !

I turned off the BTon my phone, and do not use the car as speakerphone. Kinda sticks as this was my favorite option for the car.
