Help needed with MK4 Golf central locking

vwgolf2000

Hi All,

i have a mk4 golf, not had it long, i recently noticed that the passenger door locks only sometimes when you lock the car,

If you try to lock it, it goes down and straight up again, i when around opening the doors and shutting them, but still nothing. But sometimes it will lock, everything is fine with the other doors.

Like for example i locked it the other day, all day grand locking, the next 2 days when i attempted to lock it just kept opening again.

WTF like, any help appreciated asi have to leave the door unlocked if it doesn't lock + its stopping my alarm i fitted from locking witch is a pain

Thanks

Ps the passenger window a few weeks ago dropped down and this is the same door that hs the problem, my problem is that i cant remember if it locked fine before or not

crasy dash

Best thing you can do is scan the car for any stored fault codes.

That will be a start on how to go about fixing it.

hi would the scan come up with anything like that do you think ?

crasy dash

I'm.no expert on cars but I know my a4 logged faults before the came up on the dash.

My mechanic was able to show me the times and date mileage etc .

My friend 3weeks ago both passenger doors locked shut and wouldn't release the key from dash.

30min scan with his mechanic and showed a module gone bad in behind the dash.

Theres a couple of regular posters on here who are a1 with vag cars.
Georgedalton would tell you straight away i would be certain.

Sorry I can't help you any further hope its cheap to get fixed let us know how you get on.

so thanks for you help

Regarding scanning , it could be better to bring it to a garage with an expensive scanner as the cheaper ones tend not to pick up all the codes generated.

Regarding the central locking , the actuators in the doors are known to give trouble on them and stick . id reckon this is the problem.
One other thing is , is the door fully closed, if i had the door of my golf open and tried the central locking it would try to lock the door but it would pop up again.

Out of curiosity is the passenger side carpet wet by any chance, any problems with electric windows.electric door mirrors??

thanks i think il wait and see tomorrow what a % of people think

nope i haven't noticed any wetness or anything,,

the window kinda makes rubbing noise when it goes up and down but that could be just cus iv not it in right, but yeh the window and the mirror works find and the door opening light don the bottom,

this might be nothing but the light down the bottom of the drivers door is barely lighting, and never goes of + when driving down the road the interior lights flicker on and off, sometimes they would stay on for a while and go off

its good there is no wetness and the windows and mirrors work as they should, there is a control module under the carpet for this and the central locking and moisture can get into it causing trouble with everything.

The lights coming on and flickering would indicate to me that a door isnt fully closed
