    NCT coming up and getting the car ready. Got it valleted today and since the airbag light has remained constantly on. Got new alloys and tyres yesterday and the brake disc light also has come on. Are these just a result of the work carried out and will rectify themselves? Will the car pass the nct with the warning lights on?
    Did a check about the airbag light and saw that maybe a sensor got unplugged from under the car seat, but everything looks plugged in. A friend then also said his brake light also came on when he got his wheels changed, but went a few days later as the fluid (or something) needed to run back into the disks.
    It's a 320d E46 bmw 2004, thanks in advance!

    The most likely explanation is that a connector was knocked loose while it was being valeted. Check the one down at the seat belt receiver as well as under the seats.
    As for the explanation about fluid going back to the discs, that doesnt make sense as no fluid should've been touched while only changing wheels. If the light is on check there is enough brake fluid in the resevoir. Does the car have a tyre pressure monitoring system?

    Thanks dean. Not to my knowledge about the tyre pressure. Looked it up in the manual and it just said check brake discs. Never dawned on me about the brake fluid. will check that one. The sensor in the seat belt, is the inside the part that the buckle goed into?

    the sensor is a weight sensor in the seat base, it may be a problem with the side airbag too if a plug was disrupted.

    The airbag light is probably because the seats were moved completely forward and then backwards for the valet to do the carpet. The brake light one is odd replacing the wheels should have no effect. I doubt they will rectify themselves. I don't think the airbag light is a failure. The brake light sensor is brought up by by a sensor fitted into the pad unless this got unplugged somehow.
