Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer and allowing me to assist you. you done the right thing in replacing the brake switch because that does trigger it among other things, Now you may have to check the shift lock solenoid to see if you have power getting to it and if it is faulty or not. but in the mean time you can bypass the lock solenoid by removing the little cover on the over ride button and manually pushing it down. in the mean time I'll check the circuit .
yes but did you check if the shift lock solenoid was getting voltage and ground to separate it from an electrical problem to mechanical one? here is a link that may help http://www.mercedesmedic.com/mercedes-transmission-shifter-stuck-park/ once we determine if it's electrical or mechanical then we can proceed with further diagnoses.
ok thanx then we know it's electrical . now I.m still working on getting the circuit for that lock solenoid I'm almost positive it has a lock sol fuse
this system is a little different then what I'm used to so I will opt out so perhaps another expert may help you further good luck.
Hi, my name is***** you post the vin number please? Are you able to scan the engine, transmission and traction control modules for fault codes? Are there any warning lights on?
Got it, are you able to scan the engine, transmission and traction control modules for fault codes? Are there any warning lights on?
Ok, the the ABS/ESP control module sends the signal to the shifter to release the shift lock. You might have a bad ABS/ESP module or no power getting to the module. You really need to get a factory scan tool connected to the car to read out the codes in the ABS/ESP module. If you can locate a good used module you could substitute one and see if that fixes the problem.
