Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** sounds like your electronic throttle actuator has lost it's adaption. Try turning the key all the way on but don't start the car. Leave the key on for 3 minutes then start the car and see if it will idle. If it does, then try turning the steering wheel all the way to the left and then all the way to the right a few times to clear the ASR/BAS light.
Let me know how you make out.
Did you try leaving the key on for 3 minutes? The procedure resets the throttle actuator. Also check the fuses in the K40 relay located in the module box next to the battery.
