hello fellow w221 owners. recently bought a new key fob & car has been running in excellent condition until this week . car would randomly stall & ESP & ABS would pop up & car would only rev in D and slightly go forward until car was turnt off & started again it would be fine and eventually it would happen again. i went to the store & went into reverse & car stalled & all warning popped up & i took the key fob out to go into the store as i was leaving the car trying to lock the car with key fob the car wouldn’t lock or no buttons on key fob would work on the car but key fob is flashing red & still has infrared so i tried starting the car & the key would not turn into the ignition so i thought maybe my key deprogrammed from the vehicle so i called my locksmith who programmed the key & had him come check it out & he let me know that the key was still 100% working & that the issue could be a bad sam module or bad fuse . any tips would help to even leading me to the first things to check out please 🙏🏽
