    Central Locking ( still )

    Dear All

    Have had central locking issues for a few years , but now it's starting to get on my t*ts , it started a few years ago and prompted me to remove a doorlock and replace the motor ( not an easy job ) , which I did on both front door locks....problem sorted ...( for a while )...only to find out later that the problem was more likely caused by 'Elf and safety ( or cost scrimping ) and using "new" solder in whichever Far Eastern country VW sourced the door lock modules from.

    All is nearly well but I have one irritating problem..

    All doors lock from the remote sender unit.
    All doors lock from the key in the drivers door.
    All doors lock from the key in the passenger door

    BUT when I press the central locking button on the drivers door....all doors lock...and then the BACK doors unlock..

    This prompts me to think that all the doorlocks are working fine and it must be the control module that is at fault and needs re-programming?

    Would I be correct in my assumption ? Is it possible ?

    P.S. as an aside I recently worked on the passenger door and the drivers switch for the passenger window would not open/close it fully...until I used one of the little known VW tips of clicking the key in the door locks...problem solved. ( just found out it's called one touch windows )

    Is there a list of these VW tips like the above , which I think includes re-setting the service spanner on the dash ( I can do that ) .

    Also the Summer window opening trick by hesitating with the key when unlocking ( can do that ).

    Many Thanks
    John

    The convenience system will have codes stored which will help, where did your new door lock units come from?

    The new door locks ( rears ) were cheap and cheerful Fleabay items ( Alpha Tec ATDL 3018/9), which I suspected at first , but as they function fine with signals from both front door key locks and the remote fob, and it's only the drivers door central locking switch which is problematic in their operation made me confident of them.
    The petrol filler and boot lock both central-lock fine.
    I don't suppose the child locks have any effect being purely simple mechanical catches?

    My code reader is also a cheap and cheerful Fleabay item and will not interrogate the convenience control unit , so maybe it's off to the VW dealers for them to interrogate and re-programme?

    P.S.
    The Haynes bible shows a deadlock warning light...any idea where that is , I've never noticed one?
