Rear differential lock error f06 M6 gran coupe

[PhilGT2008]

20k miles so far and already

- air con broke and has been replaced
- cup holder flap broke and was replaced

Today, driving 50mph yellow warning

- rear axle differential lock - driving stability limited

My older BMWs were bullet proof. I know it's under warranty and all that but my view is that the new ones are made of chocolate. For 100k car I have lost all confidence in reliability. Such a shame.

Any m6 or m5 owners out there seen this differential lock error. Car is doing exactly as it says. Diff is locked. Doesn't go away after shut down or overnight.

Grrrr
