BCM and Water issue

[Stevec1]

Evening, will make this as short as possible.
Ford tourneo 2020 plate. Had windscreen replaced April 2023.
Water ingress into bcm august this year. First hint was water drips onto my feet in drivers side.
Broke down all electrics not working due to bcm have water damage.
Ford replaced bcm but leak still there, they reckon it was due to a roof rack being taken off but I have it assessed and that there is nothing to suggest that and have now had the windscreen re replaced and still have the leak.
Suggested by what I am reading could be the water pump issue?? Anyone heard of that.
Not sure what to do now as still got water dripping in and will only end up with the bcm failing again.
Am stuck and ford have been useless!!!!

Hi, I think I have a similar issue. Water ingress from somewhere that is causing a BCM hissy fit. It's freaking out all my electrics. Pretty sure it'll need a new BCM. Out of curiosity, how much did Ford charge for that? I've got it booked into the dealer next week. I've also checked a bunch of things like the roof rack etc, but can't find any issue there. Original windscreen too. Will keep you updated if I find anytyhing.

Do it yourself.

Strip out bcm
Check code on it
Buy same on ebay (used)
Get a mobile guy to come program it or find a programer on ebay & post off both units.
Then plugin to van/mpv
And off you go...

Save a mint.

You might need forscan for minor adjustments.

Hi mate Had the same problem a while back and ended up having to replace the BCM due to water damage.

The leak was coming from the roof bars. Ford weren’t very helpful at all - ended up tracing the leak myself.

Here’s the link to my original thread viewtopic.php?f=65&t=222286&p=1794121&hilit=Water+ingress#p1793334

Hope it helps.

Hey, did you manage to find the source of your leak? I'm stuck for mine. Definitely not the roof bars, and the windscreen actually looks ok. Going to do a pour test later and see what that shows up.

On some models there are issues with water working it's water up the wiring loom onto the plugs. From memory I think k it was something to do with the screenwash - but do some searching and your read about it.
