Airbag, seatbelt and tire pressure lights won't turn off
 

2004 mini. 42,000 miles airbag, seatbelt and air pressure lights don't turn off. Any ideas/suggestions re fixes? Thanks

More information is required for us to properly answer your question.

First, what were you doing/ did you do when the lights came on?

Does the car have a sunroof, and are the drains leaking? Possible water damage to the Body control module.

Has the car been in an accident, or the seats out for any reason? Did you have the seats out and turn the ignition on? This will trigger an MRS restraint system code.

Are all 4 tires the same size, and equally inflated?

Get the codes read at a professional shop with access to Autologic or equivalent software, a generic read at Autozone won't give you any information.
