GL350 Diff. lock system overheated.
Hello,
Perhaps someone has had a similar issue like I have at the moment. I have found some diff. lock issue topics in this forum here however, they seem a little bit different to what I have. The issue is when driving out of the garage, the car is in Drive, I take off the break and without acceleration, if I turn the wheel then the car stops (rather than the regular forward motion it normally should have), if I give it a little gas it moves, however I can hear some rattling noise and the wheels seems locked. I tried manually to change the diff lock settings but this didn't help. There is no other message coming up on the screen.
Recently I changed the tires from Winter to Summer but it all worked well after this. Before this error appeared and the wheels locked, I towed a light trailer on a 500km round trip. The Trailer was not heavy.
Has anyone experienced something similar and what has been the problem and what is the solution to fix this? Car has a bit under 150k miles on it and its hard to believe that diff lock is faulty already. Like most of these cars we don't do proper off roading.
Thanks a lot in advance

I had a very similar issue. ESP light on the dash illuminated, car would break by itself to a full stop when I would give it gas to move forward. I would also see the diff. Overheated message on the cluster.
I diagnosed the ESP module using MB II scanner which pointed to a faulty left front wheel speed sensor. Replacing it fixed the problem. The concensus here was to replace both left and right sensors at the same time, but I like to experiment here and there so I only replaced the faulty one. I have a second one on hand if/when the next one decides to start acting up.
I went with the Delphi sensors from Rock Auto (no affiliation).
