Replacing blindspot sensor

Hi everyone,

I found a post on this forum but I was hoping for some clarification. Is it possible to replace the rear right blindspot sensor without removing the bumper? The post I found showed photos that you can do the left but unsure on right. Any guidance would be appreciated.

Thank you

Yes it is possible on the ML, but it is a tight reach with one hand. Not sure if actually possible on the GLE but the service manual does call for removing the bumper on the GLE.

Yes, it’s the same procedure, I did both sides. However mine did not fix the issue, I still have problem, when it’s wet my left blind spot indicator light goes dim and then i get warning message that blind spot not working.....I think something else wrong maybe mirror....
