2013 CLS 550
Blind Spot monitoring warning lights

Good morning, new the forum and mercedes in general. I purchased a 2013 CLS 550 recently and it seems the side mirror warning lights ( yellow triangles) are stuck on. Anyone have any experience, incite, or solutions for the issue. Look forward to the discussions on this forum.
TIA

Just started getting the "Blind spot inoperative" warning myself and doing searches on the fix. Found some good info pointing to corrosion that means replacement. Also, found a couple so so youtube videos from Car_Ful where he removes the rear bumper and cleans things up with no fix and the other he opens, cleans and seals them from about 6 months ago noting it fixed the issue. Obviously it's going to depend on the condition of the modules if they could even be cleaned and reused.

Think the models are edited into the image! lol

The one thing that looks different from my 2012 is the bracket that holds the modules. In these videos there is a clip he is released and the module slides out. My bracket looks more like the second image in the attachment that koningstiger attached so I'm wanting to figure out if I can get them out without removing the rear bumper. Here is the image of the module on mine.
