So I've asked around a few places on the internet and figured one more couldn't hurt. Are the differential lock switches on this 2010 G55 inverted and out of order or am I crazy? They definitely appear different from the schematic in the owner's manual. I just bought this vehicle from a Mercedes dealership this week and this is one of the first things I noticed. I know I am unlikely to engage them often if I don't take it off road much but I do intend to eventually during hunting season and I need to get to the bottom of whether or not they are correctly installed and if not how to fix them.

I'm also more than a little curious as to how they got like this. I can't imagine them leaving the factory like this, which makes me wonder whether or not some mechanic that didn't know what he was doing has been messing around with them.

Yes, they are inverted. Most likely there was some work done and when they replaced the diff-lock switch cluster they installed it upside down. They most likely will still work as long as they are plugged in. Just go by the order I then II then III until you can get it in for service to have them fix that.

Thanks so much, I knew someone would be able to help me. Is that something I could have a mechanic friend do or is it a complicated procedure?

Sorry.. I have no idea, I've never removed the module myself. Maybe someone else can chime in.

Just for the record in case anyone else encounters this issue it is not a difficult fix. My mechanic was able to pull the whole unit out with a piece of dental floss and simply flip it over. It would have worked had I just followed the order of the I, II, III switches regardless. The guys over at clubwagen.com are a great resource if you have any problems with your G class as well as this forum. Thanks again for the help!

Mines was also that way, but my own fault. Heres a link to some helpful videos...
