Central Locking Problems

[baza2000]

when i lock the car the central locking locks then unlocks whether using remote or key, and even when i drive the car it locks on its own.. checked wiring in door hinges for brakes but everything seems ok.. please help am cracking up..cheers.. :blink:

Where the wiring goes through the door (in the rubber sleeve) they are known to have broken wires in there which causes problems, or it could be a faulty lock motor, drivers one is quite common to go.

agree. 99% of the time its the wires in the drivers door gator. you have to pull the rubber all the way back to expose all the wires.

cheers guys but i have looked at all the wires ing the doors and everything seems ok.. someone in another group mentioned that it could be the micro switch...? any ideas as to where that is so i can remove it and have a look to see if i can mend it...thanks

The door latch is a sealed unit you wont get into it......or if you do the rest of the mechanism will probably pack up.

Did you get this sorted, if so how plz.

I have checked the cables inside the rubber sleeves and they are all ok.

any other ideas ??

cheers.

baza2000 has not been on the forum since Jan 2010 so I suspect we will never find out if the problem was fixed.

 

Does your Xsara indicate on the dash if the doors are not closed and if so when they are closed is the message/indication suggesting the doors are still open ?

[emmas xsara]

no, nothing to suggest anything is open or any problems ay all

[paul.h]

Next questions, what year, model and engine is your car ?

[emmas xsara]

DOH... should have said at the start,

it's a 2003 Xsara estate 2.0l.

 

We've had a few problems with it besides the doors, including the starter circuit packing up. (I put in a push start button) and a replacement starter motor.  The Turbo blanking plate thingy, some prob with the MAF, (Just disconnected that and it works brill) and now an intermittent fuel gauge..

Looking at the parts diagrams there are a few different locks (latches) depending on the car VIN and a new one seems to be about £80 but if you search on ebay with the Citroen part no. they are a lot less. The door inside panel needs removing to remove the lock but its fastening screws are on the outside edge. You would need to find out which one is giving the fault preventing the doors being locked (for each door, try using a screwdriver to close the door latch whilst that door is still open and then try to lock the doors). If this does not help then you may need a diagnostic check to find the fault.

 

To get the right part no. from Citroen's parts diagrams (free service), register on the service.citroen site as another professional and a member of the Citroen Owners Club, then use your VIN (VIS) to find your car. The locks can be seen under Bodywork, Front (or rear) doors and trims, Front (or rear) door control. http://service.citroen.com/do/changerParametres

 

There are two 2.0 litre diesels, is yours the 90 or the 110 hp engine ?

 

With the MAF disconnected do you have the engine management light lit up ? You will also likely have the car in limp mode which will limit the performance.

 

By turbo blanking plate do you mean the egr valve blanking plate ?

[emmas xsara]

Hi thanks for that,

Is there any cheep readers on ebay that will work on this motor ?

although the MAF is disconnected there is NO lights lit and even better it runs FAR better than when its plugged in.

Not sure if 90 or 110 bhp.

Yep thats the one, EGR.

EOBD was not required on diesels until 2004 so you would need to check if one would work on your car. To see anything other than codes for sensors that set off the engine management light would need dealer type Lexia diagnostic equipment but there are Chinese copies of the Lexia available for around £100. Some members on here have these and on the C5 section there is a pinned post of members who are willing to help http://www.citroen-owners-club.co.uk/citroen/topic/20345-diagnostic-help/

 

An ordinary code reader to consider after checking if it will work on your car  http://www.gendan.co.uk/product_FXNT200.html

A supplier used by a member of the forum of the Lexia to install on a lap top http://www.easydiagnostics.co.uk/#/shop/4584778814/citroen-peugeot-lexia-3-evolution-interface/8000814

 

When trying to lock the car, do any of the door locks sound different or slower than the others which could indicate the problem lock ? It could be the solenoid in one is a bit seized and possibly a spray with something like wd40 may help.

 

Does the engine management light (a yellow light like an engine cross section) come on just before starting the engine to show that its bulb is working ?

[emmas xsara]

cheers i'll check them out later.

All diagnostic lights work and go out as they should, occasionally the Airbag light comes on, but that is because she has a broken drivers seat that catches the cables underneath it.
