Lock the car with the key in the door - Make a difference ?
Daler - I suspect you probably need a new one... What i'd do, is pull back the carpet to access the solenoid, spray abit of WD40 into it, move it back and forth to work it in, then try again.
If that don't work, you'll probablly need a new one.
Have you got aftermarket alarms?
if so they wont work the petrol flap solenoid, you need to run 2 wires from your alarm module. one wire tapped into closure with an inline diode to either pin 4 or 17 on the ZKE module and another wire from opening wire with an inline diode to either pin 4 or 17 on the ZKE module
Mine has an aftermarket alarm but the central locking doesn't work on the key, only the alarm hon but yeah, as stated I can see mine trying to move. I'm guna have a hunt with wd40 tomorrow. No time this morning :-(
I did ask further up in the thread if the flap lock when using the key !!
This would have shown up the fault as being alarm related...
So for now, your car is not double locked, and your petrol flap will flap about until you get it get it wired up properly, unless you use the key aswell.
Not quite sure what mlouie2000 is doing with that... But what the ZKE requires is a Lock and Unlock pulse at the same time to activate double lock (which locks the petrol flap)... You need a diode to join the lock to the unlock wires.
I'll have a look into it mate, as I believe'd that you bridge the lock to the unlock with a diode, and when you send a lock pulse, it also sent a pulse to the unlock at the same time, which the ZKE interprets as double lock !
As a temp' measure, if you want to double lock with the alarm (which also locks the petrol flap), then lock the car with the alarm fob, then just turn the key in the door to the lock position, which will set the double lock.
If you have window closure, then make sure the windows are up, as when you turn the key in the door, it stops the windows closing, and you'll have to hold the key in the lock position until they're closed !
Pin 4 - Input, Data Signal - Anti-Theft control module
Pin 13 - Input, Central Arrest Signal - Door lock switches
Pin 17 - Input, Data Signal - Anti-Theft control module
From what I can gather OEM alarms work by sending a pulse on Pin 13 + 17 at the sametime, but with an aftermarket alarm, you need to bridge Pin 4 + 17 with a diode.
But as neither are labeled as lock or unlock, I can't figure out which way around the diode needs to be.
Pin 4 - Input, Data Signal - Anti-Theft control module - UNLOCK
Pin 13 - Input, Central Arrest Signal - Door lock switches
Pin 17 - Input, Data Signal - Anti-Theft control module - LOCK
So, you want a diode going from Pin 17 to Pin 4, so when you press lock on the remote central locking button, it pulses down the unlock too, which will double lock it :thumbsup
Ok, i did mine this morning and now my petrol flap works with my aftermarket alarm
so the conclusion is.......
04/97 onwards, the ZKE plug is violet, before this date it is yellow.
you need to bridge a diode between the lock (pin 17)& unlock(pin 4) wires.
pin 4 is unlock, colour of wire is blue/red/yellow
Pin 17 is lock, colour of wire blue/yellow (on my 05/98)could be white/red/yellow on earlier cars.
hope this helps others
It's the ZKE plug, not the alarm that you need to tap into.
Remove glovebox, it's a long module behind the glovebox with 3 plugs coming out the front, and 1 at the rear of it (2 if you have a Saloon or Touring).
On the solenoid, there were 2 types of locking pins, a plastic one and a metal one, and they run through a rubber sleeve. This sleeve can split, and cause the pin to get trapped, and not able to pop out to lock the flap. I would check this aswell.
