I think will order a valve core removal/install tool from ebay and give it a try to just tighten the leaking core. You might be right.
But it is quite disconcerting that it seems to be impossible to find out the size of those valve cores, or even any reference at all, and even less any MB part number.
I wonder how are the AC shops dealing with this when doing work that requires valve core replacement on older late 90s MB cars. One size fits all?
