Had it plugged in at garage and they said can’t find a fault which I found bizarre , car driving fine apart from this , any advice would be greatly appreciated .
Thankyou

Hows your batteries?
Symptoms could be related to low charge, especially in the AUX battery

Likely to be low main battery voltage if not a defective wheel sensor which should have shown up on star

as above, charge your batteries . this happens across the merc range when voltage is low.

All the symptoms of classic C Class dud ABS sensor syndrome; although it's a bit confusing why it hasn't thrown a fault code.

Hi
I’ve now charged battery , should lights automatically go off or do I need to disconnect battery to reset ?

They'll go off themselves if it was a battery issue.

I have the exact same on my c220, mines a traction control issue not a abs. No run flat, cruise control and stop start, changed all abs sensors but still same, iv now booked in to Mercedes for diagnostic £120, not worth trying other garages or messing about, might as well let the specialists tell ya what’s wrong for £120
