Hey, key, welcome to the forum.
There isn't any LX/DX switch...if you come visit the W210 forum (the one for your car) and do a search you'll find a couple of mentions on this topic. One discusses cleaning and tightening the connections, inside the left C pillar if memory serves. Mine does this too but it hasn't gotten so bad yet that I am ready to dig in to it and I was going to confirm that location before I did.
Take care and enjoy the ride,
