I have been having this random problem when the dashboard dies completely but milometer still works all lights etc still work and no power loss.
It normaly corrects itself and dashboard starts up after few seconds as if ur turning key but no difference 2 perfoprmance..
Ive cleaned relays, and totaly sealed ecu even tho there was no dampness at all in ecu compartment..
I did think it was a dampness problem cause it only happened in rain but is happening in dry now and more so just after car has started, also the auto box tends 2 hold onto low gears for first few mins.
1ce its warmed up i can go mayb rest o day without problem happening so wondering if its gbox related as fluid is manky.
I have took binnacle out and no dampness or aparent loose cables so anby help is apretiated
