DTC fault code

[bombur]

Using my E89 to drive to work today and this fault code appeared. I have cleared it and will check if it appears on way home. Any ideas of what it could be, sensor?

Either it’s a fact ..caused by say a sticky caliper ..or it’s a rogue sensor data …faulty connector, copper slip in the pins etc..

Thank you. I'm guessing that as it's been sitting undercover for a few months with only a small journey or 2 then sticky caliper is likely?

Pass..if the fault code appears whilst driving..stop and carefully assess disk temperatures..you do of course carry a laser type thermometer?-

Of course, first thing I put in the car

Issue didn't come back on the return journey, but will still get it jacked up when I can and check wheel rotations
