The rear SAM module  obviously shorted out and ignited this past weekend. Not only is the unit completely melted but all the wires going into the area as well.

what I am trying to find out is if it's worth even considering having the car repaired? or if it's repairable? and if so what kind of cost would I be looking at.

My first thought is "No Way" God only knows what melted down the line and what was and wasn't damaged. And even if it could be repaired would it ever be the same? I say "probably not" but I am not a mechanic. and the reason I am here looking for help.

HELP!!!!!!!!! : (

I will appreciate any help or suggestions.



So sorry to hear that.What you can do is find a wire harenss from a salvage yard and replace it. Maybe a friend can help. Not too hard, just time consuming. 

Keep in mind that you will need to get a new SAM and code it to the car.

Honestly I think you are looking at $800+ at the least.

My guess is that as it is right now the car does not start? Right? If it doesn't you may be able to untangle all the messed up / burned wires so that there is no short. You may be lucky and be able to start the car.

Can you post a picture of the burned unit?

How many miles on the car?

Oh wow!


Not a great weekend for you. Very sorry man, that looks pretty bad to me. However, a 2007 Mercedes is a good car and I don't think you will need to replace the whole car, unless you have tons of money.


I would personally say that this part can be replaced. Depending on where you live, it can cost anywhere from $1000-$1,500 but it can be fixed. If everything else is fine, it should be okay
