Unlocking with lock button

[corfco]

Hi All, i have had an issue for a while, wondering if anyone else encountered.
My fob works as it should, one unlock for drivers unlock only, two unlock presses for all boors and boot to unlock.
I have noticed if i press lock once all is well, but if i double tap the lock button, then the passenger door unlocks, (leaving the others locked).
Anyone else had this?
Thanks

PS also generates two pulse when i press lock, should this just be one?
2007 1.9 TDI 100 4 door.

I have added a youtube video of symptoms and steps taken at

has anyone else experienced similar?

TIA

Simple answer is don’t press lock twice. It’s unecessary.

Thanks for the helpful advice.

According to the vehicle manual, double pressing within 2 seconds disables the 'Safe' double locking system and the interior ultrasonic type alarm sensor, so it can be necessary.
Anyone else?
