all warning lights and won't start

[ian3j]

I decided to wash my berlingo multi space 04 in work while on nights ( two nights ago ).  The front windows was slightly open, we got those wind deflectors on,  didn't realise until i looked at car 15 minutes later and the lights was flashing on and off.  Got inside and their was water in the foot wells and all the warning lights was on and stop light too. And it wouldn't start either.  I did manage to get it started and get home in the end.  I took out the bsi ( fuse box under steering wheel ) the day after to dry out.  Today put it back in and still the same.  I have tried to do the reboot/reset but that ain't doing anything.  The thing is my keys don't have buttons so I cant do that part of reset.  It's just passed its MOT and was so chuffed and happy with car, till now.  Any help will be very appreciated.

If the water got to the BSI it more than likely got to it because the drains below the windscreen wiper panel are blocked.

Remove the wiper arms and the plastic panel and clean out any crap that's there and flush some water down the drains at either side to make sure they are clear.

Are you sure the BSI is fully dried out, did you take it out of the black plastic case to dry it out?
If you didn't there could still be water lying inside.

You may have to remove it again to check.

Check that there is no water in the terminals of any of the plugs.

I will check the drains tomorrow thankyou.  I have taken the board out of the plastic today and will use a hair dryer on all of it.  And hair dryer the connections too. So what you're saying is once completely dry just plug it in and should be fine, as been perfect till I washed it.  Their wouldn't be anything on the passenger side.... I know I've got to sort the heater blower out as only works on the 4th setting. 

Fingers crossed it works tomorrow.  Thankyou for being so quick in responding as have used this site so much since I've got the car.  It's brilliant and so helpful

Don't worry about the remote key fob bit on a BSI reset just skip that bit. As jj9 says get everything dry but before you disconnect the bsi disconnect the battery and when dry plug everything back together then connect the battery.

Just make sure to get it bone dry, water has a habit of seeping under things so it may look dry but the small gap under say a relay could be holding water. Put the hair dryer on it and leave it blowing on it for 15 minutes, you want to evaporate any moisture out of the board.

Remove all of the fuses, take a picture of where they go first tho.

Give the board a good look over and look for any signs of corrosion, or cracked solder joints.

Then reconnect the way Tomcat says.

Hope it all comes good for you.

Hi all
Got in car with hair dryer this morning for a good half hour going on all connections and just in the area. Did the same with the circuit board. I cleaned under wipers, a little bit but not blocking the drain hole. Put board back in re-connected it all and then re-connected battery. Did the reset and still the same..... won't start and all warning lights still on and stop light too, and head lights on. It does turn over fine. radio works, windows work, central locking don't work. If I had hair I'll be pulling my hair. What next sorry guys...

It sounds like a BSI problem to me,  I'm no expert on electronics but it's normally always the BSI that causes problems like you are having.

If the BSI gets wet drying it out normally cures the problems but not always.

The BSI may be corrupted because of the water causing short circuits, but like I say I'm no expert.

See if anyone with more experience of this type of fault comes in with advice on what to do next.

That's what I was thinking.... thankyou for your reply. Wish I never cleaned it... Going to take it out again and dry again... You never know

[jj9]

When it's out get a magnifying glass and check the solder joints and the pins that the plugs connect to for corrosion, if the pins are discoloured or show any signs of corrosion gently clean them up.

Check the connectors in the plugs on the car for any signs of corrosion also.

Search on Google for images of Citroen BSI 's you will soon find images of some with water damage, some are extreme but at least you will know what you are looking for.

Just to let you guys know. We are back on the road. Had to take it to the garage and they fitted a new BSI and all running now at a tune of £780. Not what I wanted but is fine now. Thanks for all your advice.
