Hi, I have a problem with my Audi, it shakes rarely at idle more so when its cold. It's annoying and i want to diagnose the problem before it gets any worse, possibly a faulty coil pack or flywheel maybe? Was just wondering if using vag would help to diagnose the problem as i am new to it, or any other suggestions. I didn't want to take it to Audi as it would cost a fortune before they lifted the bonnet but i do use them to service my car. Its a 2001 Audi A3 Sport 1.9 TDI PD130 with 90k. If this will diagnose the problem where can i get it done, and has anyone near Tyne and Wear (Newcastle Upon Tyne) got it? Was wanting to get the problem sorted asap as i am geting the car remapped by Revo next weekend and didnt want the map to make the car any worse. Would appreciate it if anybody could help. thanks.
