Thanks for taking time out to diagnose for me!! Nice to meet and love the car too!!
The update: Unfortunately all sources seem to point to a faulty module. This is my case, obviously every case could be slightly different.
As it happens I got back to the office and had a quick browse on ebay. As you do.
Pinged up with this beauty http://www.ebay.co.uk/itm/262701893282
I went for this one as opposed to another one with is the superseded module for my car. This is because it's a direct replacement with the one coming out of my car.
This is the link to the superseded module, incase anyone is interested :wink: http://www.ebay.co.uk/itm/262701910487
So maybe my woes will come to an end sooner than I anticipated! ...watch this space!
Well hoping it's going to be a plug and play like you suggested...
Are you able to do the internal coding for the module? Changing VIN etc. So that everything ties up nicely? Instead of possibly running conflicting information? You mentioned it yesterday but we didn't talk about coding!
I'll keep everyone updated once I've managed to take the centre console out and test it out!

Theres a well reputed Z4 breaker on ebay selling part 6965147 which is the superseded version of my ECU, if you're any further on diagnostics then possibly worth hitting it up? Don't come up very often and when they do they're extortionate. Maybe worth lifting your centre console out PARTIALLY just to read the part number? Then you know...
Hey guys,
if you need some help, by replacing and reprogramming some Sim85 or SBSL an SBSR let me know,it.
I replaced and reprogrammed many faulty modules in germany, its not an easys job, but it works.

Right so I managed to sort my airbag. The dash looks a bit strange without the red airbag light on!
My conclusion. If you've got a problem check it's not something straightforward like the seat occupancy sensor or seat belt tensioner. Those will be quick easy fixes, well relatively speaking. So get your hands on a decent diagnostic device and see whats what for you. It'll pay to do good diagnostics first. Either by yourself or paying someone with good kit to check for you. It'll save you muddling around looking to fix things which aren't the problem.
If things point to the airbag ECU module then try resetting the car and drying the module out. A few people now have had issues where the module has got wet or a bad connection. If you disconnect the battery (20mins) and then remove the module (leave to dry and maybe spray with WD40) then try reconnecting. Obviously you'll need to run diagnostic software again and then try clearing all airbag codes.
Finally if all else fails you've probably got a bad module. I took off the centre console to take a photo of my module. With this you can find out which part numbers are interchangeable and look out for a used one on ebay. Once you've got this you can plug it into the car but it won't work without programming the module. You'll need to change the VIN or chassis number on the module to suit your car. This'll need to be done with specialist coding software. You also need to take care you don't mess anything up if you do this yourself as it could brick your module - not trusting myself I paid someone to do it! If you're a perfectionist you can even code the mileage (of the module) to that of your car as well.
If you do a full diagnostic reset now you'll be airbag light free!
Hope this helps someone out and if you need more info, etc. feel free to PM me

I know I'm resurrecting an old thread here, but I am having the same problem and, in doing my own research, I came across the following list of part numbers for the control units (from realoem) and whether they are interchangeable or not... Perhaps this will be useful to others!
