BSI Swap Issues

I would suggest it is the battery which is causing the faults with your car. Electrics can start to misbehave if the battery is getting past it and the early economy mode suggests this.

im not saying that the battery wont be causing this fault but the triggering of economy mode has absolutely nothing to do with battery condition or voltage. its done by the time certain things are switched on for.

Just seen the post about having a new BSI and then goes into ECON mode immediatly...Had the same thing happen, car would not start and an assortment of problems, bought a New BSI, installed, took to the dealer for the software installation. They said they did not need details from the old BSI, just as well as it was gone....
So now always comes up with econ mode straight away, BUT it is not in econ mode as it drives without a problem, except no radio, lights do not flash when remote opens and shuts doors, interior lights do not work and poss something else, but all will work if the ignition is on, and it runs ok. It has a new battery,(the correct one). Took back to the dealer twice and had it reinstalled, still no luck. Also it shows in French that the fuel door is open, strange as I cannot see a sensor there and the fuel flap is on the opposite side.

So just happy to see another fault of a similar nature out there, as the dealer said they had never seen this before...
As for putting the old BSI back, I would if it were me but mine was nackered, confirmed by BBS and they kept it, saving me the cost of confirming it 'had it'. Should be no harm except it may now be programmed different on the keys and immobiliser as that I think is changed with the installlation of a new BSI...Installing a BSI is not difficult, all the plugs fit into their own space and it is hard to mix them up. Just a little fidgety.

Now There is another problem, abs fault showing and after checking vacuum lines now showing pollution fault as well, and the thing was using too much fuel about 28mpg and yes I drive economically...This extra things happened after checking the fuel filter and vac lines, maybe I upset something..........
I do not have a Lexia so no codes.....I need to find a good samaritan in Hampshire (UK) or ...?.........
This car does nothing for good relations with the French, otherwise it is a pleasant car or could be or maybe? Peugeot are ok, this is my first Citroen and maybe my last.........
Any ideas......Oh this is a 2.2 hdi c5 02 reg with 84k

Hello guys. I have small problem with my c5 2008y. X7 estate exclusive.
I change the ECU fuse box under bonnet BSI under glow box and imobilizer. All programed and working great.
But this set was same year of manufactory and engine size,just from saloon.
So now not working rear wiper and boot open only with key. Any advice?
Many thanks guys.

Your BSI needs telecoding to ensure the factory fitted options you have on the vehicle are configured. Saloon models did not have electronic tailgates. There may be other issues too that you need checking. You will need Diagbox or a professional capable diagnostic tool or dealer to do this.

Thanks for replay. Lexia see wiper and can tur on also see stalk witch is also working. Just can't connect them. Only lexia can see and do seperate

[degut94980]

Or there is only one way.
Put back old BSI and recoding key?
Thanks

I'm sorry, but I'm having difficulty understanding what you have written.

Yes, the BSI, Engine ECU and Fob Transponder must match.
You may have taken a matched set of the above items from another vehicle and installed them, but your BSI must be configured for the vehicle into which it is going. This means the Engine type, Gearbox Type, Dashboard Options, Telematics, Factory Options, LDWS, Parking Assistance etc. etc. etc., Without this you will have a vehicle that is non-functioning.

Thank you for your time to explaining that.
Also have question about electric child safety. Maybe you know where could be a problem,when press buttom on door panel. light come for second and can hear lock on one door. No any warnings on dashboard. And after couple min it is unlock. Nobody can tell me where I need to look

[GiveMeABreak]

All these issues will be related to getting the BSI properly configured, as the type of central locking (simple or dead locking) is another example of features that need coding.

You will get lots of issues until you get it completely configured. A dealer can do this for you from their servers as you probably won’t know what all the component codes or correct options are. There are too many to list here.

[degut94980]

But this problem start on my old BSI

[GiveMeABreak]

Ok, so that's new information which would of been helpful to know beforehand.

In that case all I can suggest is you get a proper diagnostic done with Diagbox, make a list of the fault codes, read and clear them , then re-run the diagnostic again and then provide all the fault codes. Otherwise there is little troubleshooting we can do without this basic information.

Hello. Again. Need some help.
Try programming old bsi which is my estate. I just plugged in and all futures working. Only I can't reprogram key. Have pin for my car vin code. But bouth bsis have this pin allready. I using diagbox v9.68. Here I find just key programming not learning. Can any one help with this. Thank you

[GiveMeABreak]

Key programming is what you need if adding a new fob. There is no ‘key learning’. There is only programming and synchronisation, but you don’t need Diagbox for synchronisation, when you have disconnected the battery for example.
