Just to be clear, after 18 months and 14000 miles my Audi A3 etron still has software issues which causes the MMI system to reboot randomly, it disconnects phone calls and until it has restarted I have no control over the drive functions. An SOS failure still occurs which disables the bluetooth system so I have to stop and make or receive calls manually. These faults could occur within 2 minutes of starting my journey or 2 hours later, they can also recurr repeatedly within a few minutes so there is no trust in the system. Audi should be ashamed for having released this car on customers and then left them without a fix. Fortunately for me this is a company car, sadly for Audi our new fleet won't contain any Audi's.
