Customer Question
Hi, my name is...

Hi, my name is ***** *****. My rear sam is faulty as a result of my s430 took in water from my drainage clogged. I confirmed that all the fuses on the sam are ok and it is getting power from the battery on the large wire.

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

My issue is that I replaced the module with a used one from a similar car model with a matching sam. the model number on the sam were different but I have researched that it was compatible with my car. The issue is that I installed the used module and it did not make any changes

Mechanic's Assistant: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to Mercedes Experts (you only pay if satisfied). There are a couple customers ahead of you. We can help you for less if you're not in a rush. Are you willing to wait a bit?

I will be willing to pay if I will be getting the info that will get me to a solution

hi, my rear indicators, fuel level, truck close, truck light and more features
the rear sam is faulty. I did some research on my error messages of "defective display" etc, and it leads me to the rear sam. I disassembled the sam and saw that the circuit board corroded and damaged.
Customer reply replied 2 years ago
I got a used module which I researched to be compatible with my vehicle, but it did not make a difference. I was told that the used module was already programmed
Customer reply replied 2 years ago
I confirmed that all the fuses on the modules were ok and have power on them

Customer reply replied 2 years ago
I did and there were lots of codes even for other modules. I was thinking of clearing them and see what are current issues from old codes. but I didnt
