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 .

I did that.I have replaced the whole shifter but still I have the same issue.
Expert:  Peter Bagley replied 10 months ago.

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.

It's not getting voltage but the selonoid is good.

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

Customer: replied 10 months ago.
Ok.I did check all the fuses and are all ok.

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.

Got it, are you able to scan the engine, transmission and traction control modules for fault codes? Are there any warning lights on?

Customer: replied 10 months ago.
It's displays ABS system,Elect.Stabil Progrm.ESP
Expert:  Marty replied 10 months ago.

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.

Let me know if you need anything else. Please remember that you must rate my service in order for the website to credit me for helping you.
