E60 restraint systems fault

[Andye60msport]

Hi everyone I'm Andy 

have recently come back to the bmw after a long time away with the jap scene. 

Anyway I have a bmw e60 m sport and everything was fine until last night when I went outside to start the car and pick the other half up from work and I get the restraint systems fault on the I drive,also air bag and seat belt lights are on in red. 

Ive done the usual Google search and seen that there is a common fault with the passengers seat pad and that you can buy a bypass module for it,so decided to have a look under the seat before I brought one and it turns out it already has one fitted ? Small box connected to 2wires blue and white. 

What im confused with is if it has a bypass fitted what can have brought the fault on again ? Thanks everyone.

Hi Andy...welcome to the Forum...and welcome back to BMW

The unit could have gone faulty I suppose but it is just a bypass mechanism but should have some electronics in it (resistor/diode)

For what they cost, I would be tempted to put another one in as this has clearly been a problem in the past for someone.

Let us know how you get on with it
