RE: Gas cap won't latch - 2

I think I see the problem. The plunger is too far forward. Pull it back toward the filler hole.

Here's a pic of mine. See how the plunger is further back?

Looks like the filler is stuck in open position in the second picture

I had this happen on my GS while on a trip. Had to ride with the tank bag holding the cap shut, with the occasional whiff of petrol fumes!

I looked at the latch on map cap and it appears to be in the same position as yours in pic # 4.
Take a close look at the hinge to see if you spot anything wrong there.

My I close my gas cap I'm in the habit of lifting the cap tab as I close the cap.
If you do not do the same, try it and see if it helps.

I have tried that numerous times, both lifting the cap tap and not lifting it. It just will not close flush. There is a vertical pin located under the electronic device that moves in and out to lock the cap, but it stays under the fixture and doesn't seem to do much other than to provide a track for the lock.

I tried pushing the locking tab as far forward as I could and then pulled it out as far as possible. While it moves very easily it will not move further than what is shown in the two attached photos. I tried pulling on the catch as far as I could with a pair of pliers, but it still won't latch. I looks to me like that pin should extend upward into the hole in the latch, but it won't.
If I can't fix the cap locking mechanism by the weekend, my final solution will be to just yank the locking tab out of the front of the fuel filler and that should allow me to fully close the cap as I am pretty sure that the catch is in the wrong position to allow the cap to close. The cap tab must be hitting the catch and that is why it won't fully close. If I yank the catch, it won't lock, but I don't care about that. I own more than one motorcycle without a locking gas cap.

You need to use your fingers and slide that plunger back so it looks like my picture.

This is the part I'm calling a plunger.

I might add that I have always followed BMW recommendation regarding shutting the fuel cap. I just push down firmly, until I hear a click and it always latches - until this time.

I also checked my BMW Service manual DVD regarding removing the filler cap mechanism. The instructions appeared to require dismantling the top half of the bike to remove the entire fuel tank and then you can remove the part with the electronic latch mechanism, which is attached to an electrical wire that connects to a controller somewhere. So far I have not been able to locate a parts fiche that shows the fuel filler assembly to see what a replacement part might cost.

No, you need to slider that plunger back, not forward.
