99.9 miles to gallon

My MFI has all the functions operating correctly except one which says average fuel consumption of 99.9.

I have had this Cab now over 10 years and this has never bothered me but what might be the problem.

I bet its an easy fix does anyone have a clue.

Sender Knackered or bad earth  :dontknow:  ive given up on my MFA, the other day my oil temp was 467 8O and i have done a trip to SWM = 200+ miles, whereas the MFA made it a measly 73!  :dontknow:  :dontknow:

Everything else on MFI works all warning lights and guages work Ok.

Anyone any idea where to have a look for sender/unit that sends this fuel signal.

As I said its always been like this but would be nice if possible to get correct reading.

Steve_Matthews really is (was) a fountain of knowledge and taught me a thing or two.

any ideas where the great chap is?  :dontknow:

Mine also reads 99.9 MPG  :cry:  If only it were true.

As for Steve Matthews he's driving a 1976 Mk1 Polo these days after writing off his Black Mk1. His girlfriend, Golfnutter, is still waving the Mk1 Golf flag but they seem to be keeping low profiles on this and the PVW (veedub.co.uk) forums lately. I think Steve still contributes on the Olds Cool Dubbers (??) forum though.

Todat removed kneebar looking for a rattle and found a very small bore vaccum pipe hanging loose,where does it connect to behind instrument panel and is it easy to get at.

Any links or pics would be helpful.
