[soton]

Had a terrible couple of weeks with the car...

Just replaced the starter motor and on first drive today heard a pop in the back causing a host of warning lights and eventual engine cut out.

Looking in the boot I could see that the positive had been disconnected...

After research it looks like its the BST which has popped itself off for some unknown reason.

I have an MOT today but the restraint system warning is now on. What can I do?

Some people say it needs replacing? But looking at the part its just a cable? Or will a code clear sort everything if I ask them to do it on the MOT?

Thanks.

EDIT: Just been outside and tested, the car starts fine but the airbag warning lights are still on. Im guessing I'll need to replace this lead which is costly... considering I wasn't even in a crash?

You'll defintely need to change it out. It won't clear until you do. I'm surprised the car is running due to the design of it and not allowing a restart after the charge explodes.
