Hi bokkerijder
I had a similar issue a when I first got mine (2013), it would engage difflock but would always pop out and disengage within a short space of time. Have a look at the parts diagram below. It turned out to be the plastic shroud (2) had come loose from its mounting and was fouling the diff lock lever, preventing it from being able to be fully moved over. The shroud is only held in place by gravity and can be easily dislodged. It can be accessed from inside the vehicle. You need to remove the centre matting and then both levers (4 & 9) as well as the rubber gaiter (6) and foam squib (7). ![]() Click image to enlarge |

Thanks for your input. Nothing seems to be out of place from the lever down to the U link. Already checked that.
The U link got the Vise/Hammer/Pliers treatment and All is working fine now. Not the most elegant solution, but at least it works like a charm now. ![]() Click image to enlarge ![]() Click image to enlarge |

It’s a use it or lose it scenario with the linkage for the diff lock. Periodically lube the mechanism from underneath and also push the lever over from time to time, say before going on a journey or upon returning if you’re not using it frequently…..this should keep it happy.
Also it’s worth putting the box into low every now and then thus exercising that linkage. You don’t have to be going anywhere, just get into the habit of doing it now and then. ![]() |

What lube would people use on the mechanism? I've got a choice of standard lithium grease, graphite grease, silicone grease, moly grease, ptfe spray and plain old engine oil. If I use normal lithium grease, will it all end up caked it crop from the road? 2007 110 TDCi Station Wagon XS

I just sprayed a little motorcycle chain lube onto it and that worked but due to the location of the linkage i think any lube will melt due to the heat from the exhaust so be prepared to get some drips.
