Skoda superb II elegance

 

Driving down the motorway and heard a loud beep and a lot of warning lights appeared on the dash. abs, ps, stability control, handbrake7. The tyre pressure and glow plug are flashing and also have no speedometer, when I turn the ignition off the power steering is still operative. I can start the car as normal and drive as everything else is still working. I have checked the fuses and all are OK, the battery voltage is 12.45 and 14.2 when engine running. 

Welcome.

I take it you checked the battery terminal was tight.

Checking earths might be the next thing then. 

Battery terminals were cleaned and tightened the earth to to the suspension turret is also tight.
