so does this mean new lambda sensor, would this cause the trouble i described earlier?

If it has been sat around it might be the old petrol, put some fresh in and some injector cleaner and give it a good run.

it had no petrol in it when i got it and ive done a whole tank in it since... and ive drove it like i stole it since i got it... lol... why would it be telling me the lambda's not working?

[hainesz]

can anyone shed some light on the vag-com code?

if you want to be extra certain that its the lambda, check the resistance with a multimeter. and you should have your answer, you can get the ohms readings from auto data or tolerance, i can post them if needed
