Thanks Hanno - Ahh, so the front portion of your tumbler was separated also.

The big question for me then, are you certain that the rest of the tumbler needs to be in the #1 position? I can't get mine there, but the tool goes in fine.

Also, not sure if you have the exact same setup as my w124 300e, but I just heard back from someone that there are 2 holes that the tool has to go through after the first clip to release the detends for the removal of the collar.

Thanks Hanno for this - Ken / Mark
