Could be exciter ring on the abs corroded. Happened before when the auto box doesn't know how fast the rear wheels are turning and goes into manual. Or it could be something completely different 😁

abs module fried behind dash. Happened to me two months ago. Has to be done a Mercedes as they have to program it to the truck.
There was a long back order for the parts but I got mine within 5 days.
£2000 for the part!

You need it plugged in, or see if u can get a fault code out the dash. ABS control units do fail on these and loose communication. If u get it plugged in and its not talking to ABS then the ECU is failing and needs new or sending for repair.

Disconnect one of the battery terminal for 2 minutes and put back up and you are good to go.

I had this problem on one of the hired trucks in the company where I am working, don't know what was real problem but that truck was dehired due to this problem. It's not only gears but tacho was not responding as well. Some problems with truck brains.

Brake control unit. Had in on one of ours. The part is on back order. The truck was in MB service for 3months. At the end I found the guy, he manage to fix it, but it's pricey
