Locking or not locking fuel filler flap

[Santa-2512]

Dont suppose anyone can do me a short video with the FFF open open & then lock the bike remove the key and wait?


I want to see what the mech does when the unlocked window times out and then when the bike is unlocked


and then started

 

[fred_jb]

You may be right,

Ive just been out, and the fff opns with the bike running, it shouldnt

I need to have a look at how the mech works to understand it

I guess the locking pin is to stop the latch being depressed, but to do that the bar needs to move,

i think its the bar not moving, trouble is i dont want to be playing round with the fff on a hot day.


I'll havea look when it gets cooler, if not its off to the dealers

Sounds like a similar problem to mine then.

The first time it happened to me was while touring in Spain and I had to ride about 100 miles with only the tank bag holding it down and the smell of petrol vapour wafting over me!

just warm up the mechanism when open with a blow torch. What could possibly go wrong

Mine wouldn't unlock at a service station in France last year. Used a T25 Torx to open it, WD40 seemed to get it to working correctly again but a few weeks after I returned home it failed again so complete assembly replaced under warranty. This was last October, been ok since. Touch Wood!

Sorry just re-read your original post. Didn't read it properly first time. I replied thinking that you couldn't open the flap

seems post 14 and Delboy did the same

No i understood that after it had been opened it would not lock again. Despite taking fob out of range. It should lock itself after a certain time.

Ok so i've gone out and tried my one, and here are the results. Take key fob within range and switch on ign, switch off again and open the the FFC then close it and take fob out of range of bike (check by pushing keyless button and see if red light on bottom left of screen flashes, if it flashes then key fob is out of range) I put a stopwatch on it, and it locked itself within just under three minutes. Hope that helps.

Heres what i get


Pic 1

Ignition on - FFF wont close

Pic 2

Ignition off - FFF wont close

Pic 3

Ignition cycled mech can be moved to let pin pop up - FFF can be closed


With the FFF closed

i can run through all of the permutations with the key no where near the bike and the red tell tale flashing

ans i can open the FFF every option bike running - bike not running bike not running key nowhere near

Im thinking dealer needs to replace the whole thing as its obviously not working as it should. Incidentally after reading a post on here i removed the Givi tank ring and sold it and the Givi tankbag. I bought a BNIB BMW 7 litre tankbag for the low price of £65 and thats what i will be using. Not quite as convenient but hey ho, its all part of the journey.

What was the thrust of that post you refer to. Although this is the 3rd GSA my Givi ring and bag have been attached to I cant help thing that there is some strain around the filler cap area. Ive noticed that BF17 ring just digs into the paintwork when tightened.

Going to check mine opens as I have just fitted Givi tanklock

IIRC it was that they thought that the tankring had been tightened too tightly down and that was what was jamming the lock mechanism somehow. So rather than have any problems with my one, i decided to change, although i hadn't made the bolts too tight, in fact i think they were too slack but i didnt want to tighten them up any more just in case.

Did you find a remedy for the fuel cap not locking Santa? as mine is now doing exactly the same as you described!

Similar story, mine wouldn’t unlock at a service station in Forli (Italy) which is about 90 mins from Ancona, and our outgoing port for Greece.

It was 4.30pm, very low on fuel and knew I didn’t have enough to get to the port the following day, but I’d read of such nasties and had the right size torx to remove the bolts so I could fil the tank… great idea, except I’d fitted a Motech tank bag ring with allen bolts just before we left home and didn’t have the correct allen key bit! Fortunately there was a BMW dealership 30 mins away that didn’t close until 6pm, 5mins after arrival it’s fixed. Filled up and we’re set.

3 weeks later we’re back at Forli again (great digs) and low on fuel I try and open the cap… you guessed it, no chance. It’s worked faultlessly for 3 weeks in Greece, but here we are again. I eventually get it open, but I won’t route via Forli any more and It’s never jammed since…

Think it gives a few minutes after you turn ignition off that allow you to open the fuel cap. Then it locks itself. If you wait to long to open it you need to switch the ignition on and off again to allow you to open it. Thats how it works on my bike.

And mine

Told by my local BMW dealer in Angouleme to file down dinks and if I still have a problem to give it a good thump! Bike 7 years old and to a replacement unit is 334 Euros to supply!

FFS, read the fuckin manual. It’s exactly as Del Boy says. After turning the ign off you have a short time within which you can open the cap. Thank fuck I ditched my 1250 and went back to an XR with a proper key.

The op mentioned leaving it 4 hours, hardly a ‘short time’. It’s faulty. How big an issue it is depends on the bikes use, weekend warrior not really a problem, daily commuter left parked up all day might be a problem.

The locking pin needs to be lubricated periodically. When it's dried out from fuel splash this can cause erratic locking and unlocking.
Mounting a moderately heavy tank bag to the fuel cap ring is insane, it was never designed to hold anything like that.
