Go into your trunk. On the two sides are two small tabs to turn and will open the compartment to the rear lights. The lights circuit board is clamped to the light lenses with small tabs, just push the tabs a bit and pull gently and the entire thing should come out. The assembly should look like this:

Pull out the main wire connector. The main problem with the recall is the brown wire that is ground. The malfunction is that it burns/melts the surrounding plastic. If you can pull the main connector out and see visible melt/burn, then take it back and tell them to redo it. They clearly didn't do a good job.

If this is something that showed up immediately after having your recall repair performed, the dealer needs to diagnose and repair. Don't let them blow you off with the old "we didn't do that" BS.
It is up to them to prove that they did not damage or somehow misconnect your indicator wiring while working on your indicator wiring...seems pretty likely!
If they won't budge, call MB USA

Just curious if you got the problem resolved? If not, just wondering if your tail lights have LED?
