Hi, I’ve had some really good help here before. I have an issue which seems common with the Z4. I have a 2005 2l roadster and the airbag light won’t switch off so it’s failed the MOT. It’s the module in the centre behind the gear stick. I have my part number but there seems to be lots and lots of different part numbers for the 2005 model and they vary wildly in price. Are they interchangeable? BMW have not been very helpful apart from offering me a part for £800! Is there anyone who can help??
