Airbag Light

[fattony]

On my V40 I have an airbag light up on the dash board, now although I know this is not an MOT failure I would prefer to have the airbags working especially when carrying my young daughter.

So how many impact sensors does a car have (I assume these are just behind the bumper?) and is there any way to identify which one is faulty?

if you have a local garage that has snap on diagnostics ask them to plug it in and it will tell you which 1 it is sorry dont know how many there are

ok thanks, when I bought the car the guy indicated it was the drivers side front, he got this info from a mechanic who replaced some struts before I bought it

Depending on the year of the car .. There are a load of sensors in the 01+ version.. The impact sensor itself is behind the gearstick ad there are a further 4 in the B and C pillars. Add in your seatbelt charges as well. I was told and I am open for correction that they have 14 different parts to the Airbag syatem itself...!

As I siad I can be corrected in this .. Que Liam Baffler....!

It's true for 2003 models, there are 14 units:

-steering wheel clock spring with 4 wires - 2 for each ignitor.
-passenger airbag with 4 wires, also 2 for each ignitor.
-inflatable curtain, 1 ignitor with 2 wires per each side
-front seat side airbags, also 1 ignitor with 2 wires per each side
-front belt tensioners, also 1 ignitor with 2 wires per each side

-4 side impact sensors, in B and C pillar, 2 wires each
-driver and passenger seat belt lock (to detect if seatbelt is used or not), 2 wires each

I suggest you look under both seats for possible loose connectors and wires.
