Hi. I have a 525d 2004. I keep getting a message on the screen saying " Restraint systems faulty" My local garage have traced the fault to the safety belt buckle next to the handbrake. He has fixed it 3 times which lasts about 2 weeks before the warning notice comes up again. Can anyone please tell me what needs doing to fix it permanently. My garage is saying there is a small explosive system in that part of the safety belt to pull you back in te event of an accident.. Thank you. Keith.

I have a 2004 BMW 5 series. I have just found a load of water in the rear passenger footwell. The seal on the door looks ok. Has anyone any ideas please. Any advice would be welcome. Regards, Keith.
