2000 1.8 20v se - fuel consumption - passat 20v se
My 2000 1.8 20v se has a fuel consumption meter which has recently started to read erratically and inaccurately. I assume it monitors the fuel intake vacuum pressure.

Engine performance does not appear to be affected in any way. Any ideas as to what could be causing the problem? Thanks.

I think it is a bit more sophisticated than this. I think the fuel computer takes an output from the ECU based on injected fuel quantities. If you are looking at the instantaneos fuel consumption, it will always be erratic I would have thought.
