Change the fuel filter yesterday. What an awful job that was. The smell of the petrol even in a well ventilated garage was truly terrible.

There were some bits in the petrol but not alot. The inside of the filter didn't look dirty at all.

Success! Drove to work today. No problem.

Thanks for all the advice and help it's very much appreciated.

Disaster - had the same problem on the drive to work. It slowed to nothing, wouldn;t go over 3000 rpm then 1000rpm and died.

No idea what's wrong with it, plenty of fuel.

I had my foot jammed on the accelerator, it would move over 1000rpm.

Could it be a belt?

Belt? no.
Try Mikes suggestions of relay 30, and mine of..
"I agree with JB. Sounds like fuel starvation, and the pump/wiring/relay/fuse are good places to start.
If you remove the rear seat, can you hear the pump while inside the car? I have done that on a B2 80 before."

Are the plugs looking wet/black (form excess fuel-suggesting ignition is dying)or white (from insufficient fuel, suggesting fuel supply problem).
Good luck-and its the weekend now so plenty of time to fix....

Any idea of the part number for relay 30. I've found a couple of different options from googling relay 30 audi 80

I think it's 165 906 381 but I'm having trouble confirming that.

Or could be the fuel pump has its last days since the filter been changed.

165906381 is correct. The relay in the car may have a different number
