All instuments work at start up in the morning and will contine to work as long as engine running.
After stopping and switching off ( the engine is now at normal running temperature) and leaving for just a few minutes and then starting up again
the Speedometer will not work - the MPG gauge will not work and the ABS
and Active Suspension warning lights come on and stay on. That remains the state of play for the rest of the day unless left to cool down for several hours.
The rear n/s ABS sensor has been replaced to no avail. No fault is showing on Diagnostic tests.
Any suggestions ??
