Info on SAM module I was wondering if anyone knew some specific information i was looking to get on the SAM module on the c-class. 
I wanted to know if when you replace the module, do you have any functions that work prior to having it re-flashed by the dealer. 
The car does nothing. 
When you put the key to the on position the only thing it does is it turns the cooling fan for the radiator on high, and the dash lights come one. 
Thats about it.

any information would be greatly appreciated.

Thankyou

ガソリンメーターが動かなくなるという症状でリヤＳＡＭを交換しました！！

Ｗ２１１もそうですが、ガソリンメーターが動かなくなったら、まずリヤＳＡＭを疑うべきですね！！

Mercedes Benz SAM (Signal Acquisition/Activation Module) Units on W203 C class Mercedes and W211 E class. Front and rear units causing lights failing/staying on and door windows/locks not working.

BBA can now rebuild these with our usual 2 year unlimited mileage warranty.

Ｗ２０３はコンピューターが約２０個付いています。このヒューズＢＯＸ自体もモジュール、コンピューターです。壊れると書ききれない位、不具合が起こります。

RE: Info on SAM module 
the SAM control unit controls many of the different features incuding wipers, headlamps, turn signals, fog lamps, horns, etc. it also monitors and sends infromation about a/c refrierant pressures and temp., coolant level, washer level, etc. it could be the fault your having but it could possilbly be the engine control unit.

there is some coding required in the sam, but i do not think it is required for engine start-up.

RE: Info on SAM module 
i have gotten pages and pages of wiring diagrams, and while going over it, all the functions that do not work lead me right to the SAM module. All wiring and everything going to the column is fine. Fuse box is powered up, no burnt fuses. I bought a $400 SAM module and put it in the car.

When i did that the car would not start when i turn the key to the start position, but the dash lights all come on. Another thing it is doing with the new module is that it is powering up the cooling fan for the motor to the highest level. I feels like a shop fan at the front of this car when this thing is blowing. ( It sort of amazed me how much air this thing pushes).

The other thing i never mentioned on my first post is that this car also had a blown compressor, and i have come to find out that i have to reset the computer to get the AC to work again with the new compressor. Also the ESP is disabled

Now my question is: When installing the new SAM module, in order for the functions that it controls to work, does it have to be flashed for the car, or not. Like i said, i put the module in and nothing worked. I dont want to have to pay a couple hundred dollars at the dealer to flash this module if its not gonna fix my problem.

And thankyou for the posts MasterBenzTech, and mbt36
