Hi folks

 

I've had the well documented (on here at least) filler flap not working issue a couple of times recently but it has opened eventually. Yesterday, however, both the filler flap and boot door refused to unlock. I've tried both key fobs numerous times. All the doors work but there is not even a hint of the flap or boot trying to unlock, no sound at all.

Any ideas on where to look first would be much appreciated. As is the way with these things my extended warranty ran out just over a month ago!

Stab in the dark - is the battery on full charge, as the odd one or 2 circuits may play up if not on full voltage.

Daft question (possibly) have you tried using the keys in place of the fob?

Reason I say that is our daughters Fabia plays up using the fobs (has new fobs as well) at times but the key works fine

to open/close all doors and to set alarm as well.

No joy using the key, tested battery today and it's fine. Time to put the tools away and have a beer. None the wiser.

This may sound daft, but on two occasions now I've found that the car's refused to allow itself to be locked at all via the remote key.  Starting the engine and switching it off again (the reverse of the classic computer fix) sorted it out on each occasion.  Presumably of no use to you, but I mention it just in case.

....the car's refused to allow itself to be locked at all via the remote key....

 

Just a reminder to anyone that this can happen if any door (usually the rear hatch, of course!) is not properly closed.  The signs are no clunk, no bleep, no flash.

Sorry to disagree, but depending how the central locking was set up at the factory (or later), the only time that central locking will generally not work is if the driver's door isn't fully shut. Most VAG cars are set up so that as long as the driver's door is shut, you can lock the car with the remote if any/all the other doors and hatch are still open, which then lock in turn as each is shut. But the alarm only then activates itself once all doors & hatch are shut.

I agree with speedsport that this is the norm.

However my yeti seems not to lock the fuel filler when all the other doors lock - a trip to the dealers looms I think!

In my particular case (see above) there were definitely no open doors at all.  Only an engine restart cured the problem, and that's been on two occasions.  I just assumed it to be one of those little problems that arises when cars become too complex and place too much reliance on computer firmware/software.

Sorry to disagree, ....

 

No problem, John,  I should of course have added "YMMV".  I related how it is with Annie, and I was wrong to assume it was universal. 

Update from Wings of Peterborough.

£200 worth of diagnostics later, they still haven't located the cause of the fault.

Would you like to come and pick your car up?

Will it run on fresh air?

No.

Please find the fault then.

Have you read the thread on here about this problem and what was needed to cure it? 
Perhaps you need to point the garage to it as well?

If the boot is also playing up, and it's not just the fuel filler flap that's not unlocking, then it sounds more like an electrical or programming problem than a mechanical issue with a lock getting stuck.

Or given that the filler flap failed first and then the boot later, it could be a coincidence that both have failed around the same time

The fuel filler flap fault can't be unknown (despite what my Skoda garage says). A mate's has just had his Audi dealership "persuade" the fuel filler flap open following failure - and yes, it's exactly the same servo unit as the Yeti, though the catch on the back of the flap itself is different - if the Audi version breaks whilst being forced open, only the inside of the flap has to be replaced, not the whole filler flap.

 

If it's not a programming issue, the boot problem could quite simply be a broken wire inside the flexible bellows at the top of the tailgate. Just like previous issues reported on here when front electric windows fail due to the wires being twisted too tightly inside the bellows between door & A post during assembly, it wouldn't surprise me if the same problem exists in the tailgate bellows too.

 

Of course I could be wrong, but if the garage fits a new filler flap actuator (1 revised part No S7P0810773D @ £21.60+vat) and the new one works straight away then I'd suggest there are 2 separate faults here.

Thank you John, very logical answer.
