Central locking woes!

[LukeLog]

Another update, now the clock/radio display has gone haywire, can only imagine that's controlled from the BSI too.

While a lot of the clock (MFD) functions are controlled by the MFD itself, the car has a data network (VANBUS for the M59) so it will be connected to the BSI for some data that is then handled by the MFD. From your other problems, it does seem like it may be the BSI at the root of them.

Our clock dash display doesn't like the cold and damp, sometimes it looks like a Morse code message

Might be back to the drawing board for this, spent a couple of hours tonight cleaning up the bsi boards with a toothbrush and some contact cleaner, got it back in but no change.

Might have to get an autoelectrician in.

Sorry it didn't solve the problem. I suppose the next place to look is the relays on the servo board. These are heavy duty and are commercially available but have to be soldered in. It might be simpler getting a BSI from a scrapper and trying that. I paid £10 for one. Just make sure its the same make as there are a couple of variants around. I think the Siemens one is more common. All this means the bsi has to come out again but now you are experienced!!!

I took mine to the Citroen main agent before I had a go myself. They had it for a full day and returned it as they could not find the fault. They suggested I needed a new BSI which would then have to be coded to the car. Quite an expensive repair. Shortly after that I embarked on fitting cruise control. The main agent told me it probably could not be fitted but if it could it would cost around £1,000. Clearly a strategy to put me off. I bought a stalk on eBay for £20, fitted it easily, then took it to an auto electrician in Bolton who did the Lexia bit. He charged me £30 and it worked first time. He also threw in a scrap BSI which I then used to swap with the existing one in the car. This cured the locking problem. 

Just had a look on Google maps to see if I can find the auto electrician. It was on Chorley Street but seems to have moved or closed down. It's now a Nutri Bar.

Hope you are able to make progress. I would now go for another servo board. It's obviously possible the other board is to blame but since the lights flash when you try to open the doors this suggests that board is working.

Hi Mike,

Today I did just that! Had to drive all the way out to Bootle to a scrappers, £40 later I had a new BSI and some interior trim bits that were neater than mine.

I've split the new board into 2 but don't yet have the reserve to go into my BSI, maybe tomorrow!

Cheers,

Luke

Success!

Got the new board in and the central locking fires perfectly, it does lock the car if I leave it unlocked a while but I assume that's a safety feature.

The only thing that doesn't work is the rear tailgate, the solenoid fires but the white plastic rod bounces back so I think there's a mechanical issue back there.

Thanks so much for your help, for £40 it's a great fix.

Congratulations on fixing your fault and thanks for writing it up on here so others can use the info. I know on the m59 models if you unlock the doors but don't open any after about a minute they will lock again so I wouldn't worry about that on yours.

Yes, mine locks itself after a minute or so. Congrats on the fix. The clue was in the lights flashing, suggesting all is working up to the servo board. I suspect the coil has gone open circuit on one of the relays. Re the tailgate, mine didn't work either. It started working after I locked and unlocked it a few times using the key. I guessed it was due to it being stiff with lack of use.
