Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for using Just answer! I'm Billy and i will assist you with this. Feel free to ask if further info is needed.
I would appreciate some further info on the matter:
- please confirm that check engine light or no other warning lights are on..........and that check engine light does turn on with ignition and then off
- how are you resetting the throttle?
- did you check anything yet?
No 'Check-Engine' light.
Given the info i already have, i can tell you the following:
- if check engine light is operational (turning on for a second, with ignition on, and then off all the time), then you are not experiencing the limp home mode......
You have a lack of power, which could be caused by a number of factors, but in my opinion, it is a faulty throttle actuator motor.
check engine light comes when ignition is turn to 'On', goes off on start-up.
You should have the throttle actuator inspected, and if possible, connect the vehicle to a scan tool, and read the live data while driving the vehicle, and this should show the faulty component.
resetting throttle: turn ignition to 'on' wait 5 secs, press peddel to floor, turn ign off, wait 5 min, restart
Again, you are not experiencing limp home mode.............but you are having reduced performance, due to a faulty component......
I would first suspect the throttle actuator motor, as it is a common issue on your model, and it would cause the same symptoms..........however, i think you should have a scan hooked, read the live data, to figure out what sensors are reading etc...to get to the faulty item.....
That makes sense, I'll follow up on having it scanned and focusing on the throttle actuator.
