Reason: added title
This part number is A2037602377. It includes IR sensor and mechanical lock for only your keys. W/o DIY you can get it only from Mercedes service after typical anti-thief formality. If you can work with solder iron, then remove this part from car's door and replace or repair IR sensor. All you need is torx20. Unscrew one torx20 screw in inner door side deep hole under door's rubber and remove part carefully. It connects to door's control module with 3-pin connector. Then you must cut metallic tooth for IR sensor removing. Now you can try to repair IR sensor. Carefully remove transparent mastic near outer red sensor's window and solder with care two sensor's pin on PCB. Then connect sensor and check it's work. If sensor is working you can fix it on the part with nylon strip. Otherwise you can replace one by any 36kHz 3-pin IR receiver from TV remote control like TSOP1736. In car side connector: green wire is Ground, brown wire +5V, white wire Data.
Hi, please my cables shows White - data, brown +5V and green +5V what to do?
Thank you
If anyone is interested, I have spare door sensors for both drivers and passenger door.
I'll be doing the 'fix', and testing on my vehicle.
If you don't feel comfortable soldering,
I can sell a repaired one, that's tested in a vehicle, with exchange,
for a fee of course.
Hi, C230 Sport Coup. I wonder if you still have the Siemens IR sensors available? I am looking for one for drivers door, 2007 Ml320 CDI.
My Summer Convenience Feature has stopped working. You can reach me directly at: jpbarber01@gmail.com
I scavenged some audio components from another C230 today and I also picked up the sensor. This will allow for some practice before I work on the one in my car.
I finished the repair today. Thanks for sharing the repair process. I repaired the one I scavenged as a test and then repaired the one in my car. Now I have an extra working sensor. If anyone needs one, send me a PM. I have $15 invested in it.
You can remove the roll pins without cut the holders or drill out. Just need to use a small screw (about 1mm) and drive into the roll pin. Then you can pull out, and you can insert back after fixing the receiver.

Passenger one was fixed under warranty though.
