New member… dreaded airbag fault

[OOMRTOO]

Hi all

I have been a long time lurker to this forum and have found many of your discussions and posts to be very helpful in keeping my 2004 E85 on the road for the past 10 years of ownership.
But now I find myself in a spot of bother with an MOT looming and unable to find a replacement part

I have the dreaded airbag light from the b-pillar control module and I know it’s a long shot as I believe I am one of many ….. but thought I’d enquire on here as no luck from ebay etc.

Looking for part number 6945157 nearside airbag ecu …. or any help on finding a suitable replacement

Cheers,
Mark

Good morning Mark, and welcome.
You've come to the right place.
I have done loads of these and have all the software needed. Others on here are also able to help, depending where you are?

Problem is going to be finding the module (then praying it's a good one). The left side (SBSL) is getting quite hard to find now. For example, I have only three left and they are spoken for, but I have 20+ of the right side (SBSR).

You need to look out for any of these numbers that say 'exchangeable'. The later the number the better.

Do NOT buy any that aren't on this list. They may suit other zeds, but you have to have one compatible with your original.

Wow… must be the fastest reply I’ve ever had on any forum

Thanks for the info …. I’ll get straight on it scouring the internet for the numbers.
I’m based in Northamptonshire and a friend of mine has all the BMW software for the e series and also the insta D and P software with ICOM. Though he has never programmed a satellite b pillar before ….. so help may well be needed.
I’ll get him to read up on this forum

The module has been damaged by water ingress From the door card as showing corrosion along the bottom edge ….. my code reader can enter the module and read all information and operations and everything communicates …. but is showing an under voltage fault at 7.2 v.
Would there be anything else that could be causing this ?? Everything else looks ok apart from the passenger well full of water

Many thanks
Mark

I would have answered faster this time, but didn't want to get your expectations too high.
Pretty certain if you unbolt the module you'll find corrosion all along the bottom, disappearing into the join. I believe one person managed to dry theirs out by opening it and using a hairdryer or hot air gun? But that's grasping at straws tbh.
Not seen a satellite module say low voltage before, so possibly an issue in the plug? They are a sod to clean out as the hollow pins are tiny.
