My Audi A6 Quattro 3.0 dti, model 2008 doesn't want to start and shows transmission malfunction contact workshop! This is so concerning as she just didn't stand without diesel and I did put diesel in but she didn't want to start after that and then that above statement was displayed on the screen. As well my glowplug light doesn't go of when I try to start the car. Could anyone please advise me on what to do!!!
