A8 D2 runs out of petrol with 2/3 tank
My 1998 A8 D2 4.2 Quattro runs fine with a full tank, but as soon as the level drops to 2/3 (about £40 used at today's prices) the car coughs and acts just like it has run out of fuel. It will not start until I have put in more fuel.
There is no indication of a faulty fuel pump when it is running and the guage seems to work fine.
I am mystified. Any help or advice members can give to solve the mystery would be gratefully received.
