MK1 dash display readings

[Dickie Dastardly]

Hi,

On the way down to Le mans this year the water temp, oil temp & oil pressure readings started jumping about on the digital display pod; it is rev affected - the higher the revs the more they fluctuate. All other display readings are fine and consistent.

All advise so far suggests an earth fault, so far -

- engine earth strap replaced
- earth point on the top of the bell housing removed/cleaned/refitted.
- earth point in passenger footwell removed/cleaned/refitted.

Issue still persists, any other areas or earth points I should be looking at?

Thanks in advance,

Richard
