Hi
First of all im new in this forum, im glad i could be a member.

My english is not so good, but i will try to explain best posible.

I have had this problem long time now, buyed this car in summer time and problem came after a while. Drived to Mercedes because i only wanted Them to check that what is the problem.
They didnt find some fail/problem with the car since the problem came one second and was gone next no cel. After some more time the problem Get worse. Car startet to rip moore and some times could turn on and off and Then was good.
I drive again to Mercedes and they tell me that throttle body was damaged, some idle sensor inside was probally broken and they suggested to change it.
I tell Them ok because i was tired of this problem and they changed it for 2000€
I pick up the car when they was finish. Drive 2-3 km and the car was perfekt after this same problem started. I drive back and delivered the car again and they startet another round. Then tell the Mercedes dealer that they are not sure what is the problem but wanted to change the gear oil because the converter could some times make the motor stall up and down If its dirty, this sound crazy for me.

I have now payed Them a lot and Dont know what to Do. Searched Google and have seen that some other people have also had same problem. My car is stock. Only Dont have limit on km.
