I have no reading at all on my Mark 1 MFA computer but my VDO gauge is working fine. Any suggestions?
are those the VDO gauges- the 3 gauge type inthe centre console. As long as you have these then you should be ok...
Check the green/black wire on top of the filter housing (the connector is on the part where the pipe run for the oil cooler if I remember correctly). The wire is probably broken.
