BSI trouble ..... again

[PeterN]

You may recall I had a problem with my Hdi estate after it had been left standing and got very damp inside, the 'key' was showing on the display and it wouldn't start, I tried several BSI resets without success, I then left it with all the doors open on the sunny day we had last months, did another reset and away it went.

Its now been left for another few days, 'key' back again and refuses to start. I have had a dehumidifier running in it for a couple of days, still no luck. Today I got the corner of the drivers carpet up and there was a little water in there but not much, the connectors look pretty clean as I waxoiled them when it flooded a couple of years ago. I left the doors open, charged the battery and tried again, 'key' still there and of course no start. The scuttle drain appears to have been blocked so I suspect that's where the water got in.

I have reset the BSI about 20-30 times now but no go, key showing every time, I have tried the other key but still no joy. Where do I go from here?

You need to put in your four digit pin code that was supplied with the car from new ,I believe anyway.
I had this with mine after I disconnected the battery without letting the bsi go to sleep
The key symbol is telling you that the immobiliser has been activated & you need your key pin code to play
Lucky for me I had the pin code,
If you don't I believe you can get it off the Internet.
Hopefully someone who knows how will be along soon.
Sorry I can't be of more help DDD.

Hi Peter.

DDD is right, if the key needs to be programmed then you will need the 4 digit PIN number on a sort of credit card that should be with the handbook - if not they are obtainable for about £20.

A chap on another forum is doing them - his website is www.carkeycodes.co.uk

Firstly though, I would check to see/hear if the car chimes if you have the keys in the ignition and then you open the drivers door - no chime then the key isn't being recognised by the car.

Secondly, check for moisture behind the comms unit ( if you have one? ) as the grey connector carries the signal from the key to the car, so this needs to be a good connection, but be careful with it...

[PeterN]

Thanks all for the info.

The car does bleep at me if I open the door with the key in the ignition but stops as soon as I take it out which suggests to me that it is recognising it.

Could the comms unit itself be damp, and where can I find it? I don't of course have the card with the key number.

Thanks

Peter

Bleeping is good....although I'm not sure why the key is flashing then.

Mossy had ( has? ) a similar issue with his 406 where the footwell was dried out but one wire had broken off the main connector, now his car won't start either.

The comms unit is the name for the wiper/indicator combination - its all one unit and not separate stalks like older 406s - if you remove the lower cowling ( 2 torx screws and a tough clip ) you should see 4 connectors behind the steering wheel.

[PeterN]

Thanks Ginger

The light doesn't flash its on all the time. Mine is the earlier type, semi MUX I think, the new one has stalks the same as the C5, does that make a difference?

I have today taken the under floor connectors apart and cleaned them although they look to be in pretty good nick, I then left the heat gun blowing warm air on them for half an hour or so, they are now completely dry but it still won't go, key symbol still alight.

I was looking on YouTube to see if there was any information, I found a video of how to remove the BSI and it shows a box with many many plugs up behind the dashboard, you have to remove half of it to get it out. Is this because it was a fully multiplex car or is this something extra?

If it's a D9 then it's multiplexed and it'll have a BSI. They're not sealed against moisture I'm afraid.

[PeterN]

That's what I was afraid of. I will persevere a little longer, I have had the car for nearly six years and done about 60k in it and its never really given me any trouble before, its done 246k now but still runs beautifully - or at least it did. All this has occured because I didn't use it for a couple of weeks and it got damp inside.

I had a similar problem. Took the dealer 10 hours (!) to diagnose and fix. They replaced the complete set BSI - ECU - contact switch, but that didn't help.

In the end, it turned out to be an electrical short in the wire harnass, I believe it was the wiring into the drivers door lock motor.

Here is some documentation about the BSI. It is from Citroën but it is basically the same:

bsi.pdf

Useful info about the connectors and wiring is found on page 16 and onwards of bsi.pdf. You might selectively unplug connectors to see if you can isolate the short.

[PeterN]

Thanks for the info, I will download and peruse it. I am going to have another try at drying the car out as I'm sure the problem was caused by the damp, although I don't know of course if its reversible, everything else that the BSI controls is working perfectly - it just won't start. If drying it doesn't work I'm afraid it will be going into the field for spares.

I have had it getting on for 6 years and only paid £950 for it then so its served me very well and its getting a bit tatty now. I have bought a very nice one for £400 which has been maintained like new apart from the fuel consumption being poor, but hopefully that will be easier to fix, so I don't want to get involved in spending a lot of money on this one, it seems a number of people have and still not got it going.

How times have changed, my first car had a 6 volt battery, a dynamo and lights and that was about it other than basic instruments. I was an electronics engineer for 50 years but don't understand anything now.

That would be a pity.

Here's a thread about the same problem:

http://www.peugeotforums.com/forums/gen ... sue-16500/

The guy who had the same problem was also going to scrap the car but in the end fixed it.

Summarizing from that:
- Connected Peugeot Planet 2000 software and read fault codes --> often gives a long list telling you nothing really (post 27)
- Checked fuses (post 31)
- Finally solved by cleaning up gunk in the fuel line (post 36)
- Could also be corroded connectors due to water under the carpet on the drivers side (post 38)

Yeah I know that feeling I'm an electronics engineer, although working currently working as a software engineer. The rare moments you really think you understand it, the next WTF is already on its way. I stopped trying long ago.

Here's another possible cause:

Summary: failing connector(s) to the ECU. Solution: unplug the ECU, clean the electrical contacts and plug back in.

[PeterN]

Thanks for the info Frog. I have been to most of those places, I have the carpet up now but the connectors although wet all appear to be in good condition, I waxoiled them when I had a different problem a couple of years ago, the floor was actually awash with water that time, it didn't stop the car from starting but all the instruments went haywire.

The car is recognizing the key as it bleeps at me if I leave the door open until I take it out then it stops. I'm pretty sure the cause is dampness, when it first happened I dried the inside of the car out, reset the BSI and away it went, I then left it for about a week and it was dripping wet inside again and I haven't been able to start it since.

I will have a go at getting the inside completely dry before I give up hope.

Good luck in finding and fixing the problem!

Seems that you are quite in the same position as my dad, who we jokingly call "fleet manager" sometimes. As he is managing the whole armada of cars of himself and all the kids + their inlaws. Nearly a full day's job!
