ABC warning on older model and shift slipping

My 99 s-class s320 has started showing warnings that says ACTIVE BODY CONTROL ABC VISIT WORKSHOP!

After parking the car the message despaired, weird its happens 3 times today right after Transmission slipping is to neutral in various speeds

Also most wired this car should not have ABC

Any advise is greatly appreciated

Your car doesn't have abc

has it rained recently ? Sounds more like some electronics problems , check under the windshield plastic grille to see if the reservoir is filled with water . Also check the tcu in the underhood electrical boxes to see if it has fluid or water on it

If there's no problems there , lastly check how old your battery is , could be errors from a weak battery
