1 minute after car is started the check coolant level alert indicator is shown even although the coolant level is correct.When car is re-started after a few minutes the check control is o.k This only happens when engine is started from cold. Any ideas,please

It is worth checking on 'realoem.com' to see if it is the same sensor as on e46 3 series.

These give this error message from cold, turn off, restart, and all okay. My e46's used to do it, and my current e93 is booked in to have a new replacement as I write.
