Because mine has stopped working and I need to replace it. I purchased a new one, and thought it was next to the siren in the shroud under the rh fender lining, but it is not

The rear SAM controls the alarm on your car. Do some diagnosis before you start replacing stuff, though. The sirens fail much more frequently than the SAM's do.

It is not part of the SAM, the part # is w2118209126.
Here is the diagram. https://www.getmercedesparts.com/oem-Mercedes-parts.html |
Its not the SAM that controls the alarm. There is an actual unit part# W2118209126 that is the anti theft control module. I have purchased the control module, but do not know where in the car it is located. That it what I am looking for.

Pope, you have some BAD info!
As ILUMILS has suggested... the rear SAM controls the alarm system. And the siren is the problem 99% of the time! The part number is 219-820-32-26 & list price is $164 |
Ok MBDOC,
Then what is part # 2118209126 for. I have a brand new rear SAM and have replaced my siren. I have gotten the part number from my Mercedes Benz dealership with the DAS print out sheet showing the fault. IT IS THE CONTROL MODULE. May be connected to the SAM but it is the module that controls the anti theft alarm. Go the this website https://www.getmercedesparts.com/oem-Mercedes-parts.html, and enter this part number 2118209126 |

If you order the part new the Mercedes dealership has to sync it to your car. |
211-820-91-26 is the Anti-towing sensor!
The rear SAM controls the alarm, that is merely an input to the SAM! And it can be programed out as well. |
