Doors not unlocking?

[Dec]

Hey guys, my doors are a bit strange.

I got a new alarm fitted the other day but the doors only unlock when in valet mode. To get around this, Ken (Troublestarter on here) had to set the alarm to give 2 pulses to unlock it. This means there is a delay which is annoying

Ken said that as there is signal getting to the central locking pump on the first pulse, it isnt the alarm that is faulty. Basically I think I need to replace my central locking pump and there is something in the drivers door that can fail and cause this aswell?

Any ideas/part numbers for the drivers door central locking thing and the pump thats in the boot?

Cheers!

i carnt see it being the central locking pump if it opens on the second signal! as far as i can remeber theres one signal wire going into the pump to open and close the doors. Maybe the signal is not stayin on long enough or not enough voltage/current, check that your going into the circuit at the correct point also. Maybe you need to find out whats different between the first pulse and second pulse, and the valet mode. If your doors open and close by your key in the door it carnt be the pump!?

I dont have any locks on the door

I cant see what it could be other than the pump We tested the signal getting to the pump and its there on the first signal.

Plus my doors unlock really slowly and have done sinse I got the car. Not sure if its just a mk3 thing but compared to my mums car it takes about 2 seconds longer.

Thats just cus its using like an air system to unlock it, so it makes a horrible noise and takes ages.

I think most modern cars use like some electric system that takes 0.00001 seconds to unlock.

Mk3 is hardly a get away car lol

Yer it doesnt take ages in that way though, just nothing happens the first time

One of the alarm install docs for the mk3 golfs specifies that the system is double pulse on unlock.

This could be your problem 

Have you checked for leaks - you can take the hose off the pump and suck / blow to test it. You will probably feel a leak if there is one in the air lines....

Oh right, seems strange as it was fine with the old alarm most of the time. Ill do the suck/blow test (ooh err) and see. This morning it unlocked first time too and also the window seems to go down when i unlock it but didnt this morning.

Been assured its not the alarm but seems a bit odd how its behaving to me

Think you should take it back to where you got the new alarm system fitted and make them sort it!

I got it fitted by my mate who has his own company Knows what he's doing though so it might just be my car
