Successful retrofit/Code Distronic, Traffic sign assist, and lane keep assist.
My GLC has the illuminated star (factory) and it still works. My understanding is that the driver assistance distronic uses a different long range radar.
Materials
1. Switch Panel ( A0999059308 ).. I called up my dealership and they ordered me one and it arrived in 2 days (IM FROM USA, EU AND NA BUTTONS ARE DIFFERENT)
2. OBD 2 reader - I used this one (Non affiliate link): https://a.co/d/9bvYe2G
3. Cheap windows 11 laptop. I also had to order a USB C to Ethernet adapter
4. T30 and T25 fittings (Can use electric screw driver).
5. Hook tool
RJ automotive posted a good tutorial on their YouTube channel. They also sell the kit and code.
Elebest (Max Yao) is also a credible coder as well
i ended up using Simon from https://www.mercedes-benzcoding.com…
Simon was able to code distronic, lane keep assist, and traffic sign reading. Everything works flawlessly!
It was overall very easy to install the switches, I didn’t have to disconnect the battery. Just pay attention when putting everything back together. I am not mechanically savvy AT ALL. I’ve only ever assembled furniture lol..
