Hi,
I'm new to the forum and hope some one can help. I have a 2009 A4 3.0 V6 TDI Quattro, I have owned the car for a year now and it has been great until before Christmas. I went to start it one morning, it started straight away then cut out and the glow plug light flashed (I did wait for them to go out before starting) it did it again then the engine management light came on. Then when I reved the engine just after it fired up it was fine and both lights went out about 10minutes later. My partner took it to be plugged in when I was at work and the code she was told was low pressure in the rail. It's been serviced everytime it's been needed by Audi. It only seems to happen when the fuel mileage is less then 60 ( around 1/4) of a tank, surely it shouldn't do this.
Any help would be great!
Thanks
Tim
