I was on the phone with my locall MB guy this morning and we came to about the same conclusion.
I wasn't sure if i did dare pull out the pin completely, because what if the guilde rail moves just 5mm's ? The pin cannot get back in.
If the pin indeed is broken "we have a problem".
Drilling a hole will be next to impossible, where would you find a 3-4mm drill more than 10 inches long, there will be drilling surplus (?) in the drive train, and can i find a 3mm pin strong enough to last the pull when the rest has to come out ?
I'm on my way to the shop for some Loctite (243 or 2701 seems to be the right type).
