Hey! so ive been having this wierd problem with central lock(all doors)+all windows.. everything works fine most of the time, but like once in a week there is this problem. But yesterday it suddenly stopped for good. Is there somekind of relay? im just wondering is there something i could do about it..

Somebody have a clue?

Four door control units, four door locks and a convenience unit, a good first step would be to get it scanned for any codes.

Well that would be the best part, but i dont have those items what would be needed to scan for codes... Could some of these relays be the problem? already changed the relay what is marked with red arrow (was having indicator, wiper etc problem, fixed with that)

Someone know what to test before buying any new parts?

I noticed one more thing, there seems to be working all the lights for switches/buttons in the driver side door, but all the other doors are dead.. Conclusion?

My windows and central locking stopped working, I was told the relay for these are in the convienience unit, therefore I changed my convienience unit and everything was working again. It is located behing the headlight switch and fuse box. I bought one second hand for £40 I think it was :-)

Just opened my inside panels and founded this (see the picture).. i taked off the blue adapter and the "black box", cleaned them both and put them back together. And the central lock+windows worked again! :sun: BUT, after 5min the same problem came back.. so is there problem in the "black box"? or is that black box connected to some relay where the problem might be? im just wondering.. relay or the black box..

Btw.. convienience unit=black box ?

Try changing fuse 14. Had the same problem with mine at the weekend. No central locking and no electric windows. New fuse and its sorted

The relay is IN the "black box" lol The black box is the convienience unit. If the problem still occurs, then yes, you may have to change the convienience unit, as you cannot change the relays in the convienience unit. But as said above, try the fuses first :-)

just change the convenience unit, stop looking for other things it could be Thats 3 folk in the know suggested it

Thx for answers someone know the part number for that convenience unit? it would be possible to go just and buy it from local dealer without needing to open all those panels again

from a dealer its likely to be expensive

You were right.. the price was something totally insane. Need to buy it second handed i think..

Well some update, i bought "new" convenience unit buy second handed, put it in my car and all the problems were gone for 2days. But this morning, same old thing... nothing works!

Im out of solution.. anyone?

Edit2: this evening those problems suddenly were gone... have to do something with moisture or wiring?

Well i was thinking to ask help for a last time.. im just wondering what is this meaning, have to mean something: When i unplug the adapter from the convience unit and then put it right back on, the problem seems to be fixed.. but after 1minute-30minutes it comes back.

I just cant figure out what is this meaning... adapter broken? :wonder:

Could the replacement CU that u bought be faulty ??

It worked great for like 2-3days.. is there a possibility that something broke the new CU too something gives somekind of electric "spike" to CU and after that its broken.. dont know. Just quessing
