my blindspots don't work anymore it gives errors. The question is where are the sensors on the sides so I can check if they are dirty or covered? so i can clean them and see if that helps. It may also be because moisture has gotten in since I have washed the car very recently.

They are behind the rear bumpers on each side. Located close to the rear side parking sensors but from the inside.

it's a lot of fun to remove bumper but is not necessary to access the BlindSpot Modules.

Save time look at it from under... wear plastic safety glasses for all the dirt falling down in your face.

The killer is leaky harness connector... BS Module is 100% watertight besides unprotected input connector.

There are a couple good threads about this on here

Here's one https://mbworld.org/forums/e-class-w...lind-spot.html

I did not remove the rear bumper. You can access the sensors from underneath. Be warned - removing the connector is difficult as it will have "welded" itself to the sensor over the years

Good luck
