Think its packed up, last time i ran the car it was low on petrol and started hunting a bit and sounded rough, like it was ready to chuck it, eventually did. Left it as i was busy doing things and was going to shops later and took tank for juice.
After filling it and trying to start its just kicking over, when planting the accelerator i can hear a faint combustion from the exhaust. Also, last time it was running as described above, i could hear the hum from the fuel pump really loud, which it never done before!
Unforunately i still havent sorted out Vagcom yet so the old fashioned way it is. Im sure ive seen RS4's etc with the pump accessed from inside the car, by lifting the back seat up, is this the case with all A4's? Mines a saloon 97.
