'98 A6 2.8Q
Hi
Driving along and car shuts down - like you had swithched the car off!
Try to start the car and doesn't happen - you have to wait for 5-10mins then it starts.
Next when you put it into D and release the brake - car shuts down again!
Had a VAG on it - no problems reported.
Please help as it is driving me up the wall!

Thanks
Ant
