Hello friends, my car was in for maintenance of the engine belts and pulleys, and after that I got an error saying "4MATIC inoperative," and the 4x4 stopped working. The next day, after not driving it overnight, it was fine again, but when the car warmed up to 90 degrees, the error appeared again and the 4x4 stopped working.When the errors are cleared from the computer, the live data appears immediately. The car was serviced on a lift, in case that’s relevant.Please help.Thanks!
