Hello All,
I have a 2012 GL450 and I would like to replace my rear blind spot assist/radar sensors. The orange triangles on my side mirrors annoy me so very much. I have found a few videos however, none are identical to my truck. I'm not sure how to access my sensors without removing the entire rear bumper. I have a tow package and a chrome plate so it looks like the bumper would have to be disassembled to access it. Has anyone else replaced these sensors on this make and year? If so how did you access them? Also did you replace the sensors with new, used or aftermarket sensors? Can the sensors be accessed by removing the grey trim piece on the bumper? I have attached a few pics of my trucks bumper assembly.
Thanks in advanceTonya Can the gray trim be removed without removing the entire bumper?

The former can be confirmed and the latter can be done by someone with an MBstar/DASsystem and the function simply coded out, or set to inactive.
probably about an hours worth of labor and no disassembly required. No reason to take anything apart until you’re certain where the fault lies..
I would like to disable the system. But from what I understand since the system is currently inoperable/malfunctioning it can't be disabled. The sensors must be replaced so that the system can then be disabled. The blind spot assist error message on my dash and the orange triangles on my mirror mirrors.
Thanks

negative, ghost rider. Find yourself an Indy with a. MBStar system with developer mode - it’s simply a question of finding the right menu item and turning a 1 to a 0, or in the case of dev mode from “ein” to “aus” - it’s all in German.

Thank you. I tried going that route. And I was unsuccessful with to shops. Neither were able to figure away to override the system.
the sensor can be replaced without removing the bumpers is latched into placed and slides out, you will have to remove the Exhaust tip for easier access.

Thank you so much for this information. I greatly appreciate it.
I just picked up a 2012 GL 450 with this issue glad I came across this post. If OP is still active on this forum I would love to know how this turned out for you.
I found my way to settings with key on but engine not running and was able to turn Blind Spot assist off which turned off the triangle lights on the side view mirrors.
That will do fine for now. I will go back and turn it back on at a later time to see if it resets itself. I also turned off the always on daytime running lights.
