540: just purchased a new to me 540i.From time to time

This answer was rated:

just purchased a new to me 540i.

From time to time the traction control, DBC & ABS lights come on and stay on.
There seems to be no loss of performance & after stoping, turning off & restarting the lights go off as they should.
The other weekend we drove 500km + with no issues then again it can happen driving around the corner!!! Car yard has looked at it several time and has not sorted anything.
Ideas please
Most likely issue is a wheel speed sensor, probably one of the front ones. The trick is to get the computer scanned to verify the condition while the warning lights are on. regards, Canuck
