These last few days I've been getting a strange "Left Mirror Turn Signal Out" error. The strange thing is that the error will come on then go off maybe 2-3 times while I'm driving, when I pull off the road to check the turn signals work fine.

If I turn the car off then turn it back on the error is gone, with no messages from the in car display.

Loose connection? Anyone get this before?

I would pull it off and make sure the connection is dry and no corrosion.

This is pretty common. My mirror signal unit had to be replaced under warranty. It will eventually go out entirely.

Check and see if the turn signal housing has water in it. You can try taking it apart, cleaning everything and resealing it, but for the price of a new one I can't imagine going through the trouble.

...you have a 2007, aren't you under warranty? As long as the housing isn't cracked MB will replace it.
