147 Air bag light

Hi people,

Due to two of the retaining clips breaking on the passenger side air bag panel (on the dash) this panel has been loose for a few weeks and just resting in position. I assumed this was maybe caused by the heat of the sun as it was a real hot day and i have never touched anything in this area.

I have only been able to get replacement clips recently but have not yet fitted them.

However, I have just noticed that the airbag light is on!!!! I am not sure how long this has been on but i am pretty sure i would have notcied it.

My questions are as follows:

i) Will the vehicle pass the MOT with this light on but panel secured

ii) Will refitting the panel solve the fault or is it likely to be something else IE what caused the light to come on?

Why would the panel being loose cause this to come on

iii) If i resolve the problem will the light automatically turn off or will i require a diagnostics tool.

iv) Could it be a coincidence that a connector has come loose and caused this to happen at the same sort of time??

Thanks everyone

air bag light being on wont fail your mot

i believe that a diagnostics tool will be required for this to be turned off - diagnostics should also locate fault

thats all i know so somone else can advise the rest but its a start

sounds like Murphys law, you need a readout of the airbag ACU to ascertain whats wrong....

p.s. the second law of Murphy.....he was an optimist

Borrowed a diagnostics tool and it came up with code P0021 - description was something like "DS Curtain squib - value too high".

Tried to clear code but it would not clear.

Disconnected and reconnected DS connector behind brake cluster and then code cleared with diagnostic tool. Have applied some contact grease to help the connection.

Easy fix
