SAM Modules
Hi all, new on here with question regarding a ticking sound in trunk...
model: C320
year: 2001
my guess: rear SAM unit? brake switch?
As of two days ago, while driving, got a *FAULTY DISPLAY* message. Gas Gauge lamp came on and turn signals would not function--all else appeared okay.
Upon stopping, trunk would not open and key fob failed to open windows or unlock. Alarm also began to go off, though was able to eventually silence it by pulling *FUSE 8* I also recieved a *BAS MALFUNCTION* as well *ESP MALFUNCTION* I corrected the ESP by doing the steering wheel reset method. I checked the fuses and they were all okay... I did a factory reset of the vehicle options as well.
Upon replacing the fuse I reset all the windows and roof as well power seats. messed with the turn signals while moving the key in various positions and eventually got everything including the gas gauge to read properly. During this process a ticking noise was audible from the trunk fuse box. When the ticking slowed everything became normal again.
I've read that the SAM units may need reseting with a Star Tool. Anyone in Arlington, VA have one???
QUESTIONS:
1. Can I manually reset the SAM in any way myself? (will not be home to visit a dealer for some time!)
2. Does anyone have instructions on how to change the brake switch?
If anyone can help, it would be appreciated!!!

You may have seen my post earlier today about my visit to the dealer, but I was wondering if there was a way to clean the rear SAM. It has some dust on it too, would it be safe to use an air duster on it, like you would a computer? I'm guessing it would be ok. With my luck, I'm probably going to need a new rear SAM. TIA.

I have been searching and reading about it because I have a strange feeling I need it replaced, but the technician told me it runs close to 500, but I know thats a steep price, because I think people on here mentioned prices in the 300s or so in some of the threads that came up in searches....

Yeah, I agree thats steep, if need be, I'd buy it somewhere else and have my local independent install it, but many of the online mercedes parts websites are not showing it in their catalogues, can anyone suggest a place where I'd get this if I end up needing it? For a 2003.
