Help ! KeyLess go problem after Front SAM Replacement
Hi guys
I'm experiencing a strange problem on my '04 E55, and any kind of help will be appreciated.
The story : few months ago, my front right turn signal stopped to work; first I thinked about the headlight, but after some search i found that was the front SAM module needed a replace. So I bought the same ref (A211 545 40 01) new OEM part, and dealer replaced and reprogrammed it.
The turn signal is back and everything works, yeah, except now i can't use the start/stop function anymore. If I use the key and turn it no problem, no error. The keyless open/close is working too. But If i use the start/stop function on the selector lever, i got a bunch of errors, for example ESP, ABS, and the display tell me that i'm not on P or N in red background, so the car don't start, and become absolutely locked (can't move the selector lever, can't turn the key if i put it in, etc..) and need to unplug the battery to be able to reuse it. Please, tell me one of you have any idea of what it can be, i'm starting to pull my hairs with these electronics cars, that getting me mad.
Don't hesitate to ask me more if my english is bad, sorry for that.

Hello Plutoe
Thanks for your reply. I'm not sure to clearly understand what you tell me. Do you mean the dealer is missing some experience ? If so I can't agree with you because he takes care of many Mercedes and AMG vehicles, slightly rare and dearer than mine, and he is very aware of the issue. Actually he's searching a possible cause, and will come to my home to try fix it freely (he is living at 1 hour from here), which leads me to think that he is involved and not just "fend for yourself". Is it not conceivable that a relay, for example, is defective or something more subtle that happens rarely ?

Out Of Control!!
I am somewhat confused, to me, when someone says dealer, I always assume that to mean an authorized MB dealer, not someone who lives over the mountain and in the next village who happens to sell and fix MB cars.
Never the less you are lucky that this chap makes house calls. I just hope he has the diagnostics to solve your issue which I doubt is a relay.

Maybe dealer was not the good word. He's not selling any car, this is just an AMG specialist garage and he's not living in moutains, but it's rather me who lives far from the city. Relay was an example, I also doubt it but I do not exclude the idea either.

According to this :

And this :

I tested the relays at kN and kP (Circuit 15) at the engine driver SAM, both are in good condition. So, what about a bad mechanist coding, is that just possible ?
