Has anyone any ideas what this means in terms of what the absolute fix is?

It would appear that by the lack of any response, the fault that was shown in the dash console must be very rare which is a good thing i suppose.

It was orange at first and later turned to red and said that i had to stop the car.

All sorted now.

just seen this thread- mine did this once then cleared itself and not done it since. Was yours a sensor issue? or had something actually gone wrong?

Was a sensor that went faulty. Was intermittent at first but then simply failed with warning on all the time.

Was replaced under warranty and all ok now.
