As above what would cause all these fault codes on my 2003 Vec C 2.2 DTi?

Tried putting it on opcom but they're not clearing?

Did they all just suddenly come on or have they always been there?

Just really come about when I changed the dash harness, and both front airbags and airbag ecu. Could the airbag ecu I put in be faulty?

Where did you get the airbag ECU, was it a new one or out of an old car?

**krazylegz** · 24th April 2012, 18:31

Out of a car in the scrappy. The same car I got the dash harness, and both front air bags from

Was the ECU divorced from the car, if not I dont think it will work.

Did you fit a harness from a car from the same year?

Did the original airbags have a single plug?
Did the ones you got from the scrappy have two plugs?

You need the same ecu as yours ie the prefix letters need to be the same as your car.
Mine was KN so replaced with one with the same KN letters.
very easy to do and this will not need to be tech 2'd to your car.
It's just a simple plug and play I know because this is what I done and it saved me over £600 from the steallers.

Yes mate my car originally had single plug airbags and the new harness had twin plugs..... This car is beginning to turn into a pain in the arse lol.

So I basically need the current ecu tech 2'd or try and get a twin plug ecu with the same starting letters as my old one?

You have to replace like for like. The twin plug airbags and harness are not compatable with your car. For a start your car is half canbus and the donor car was full canbus.

Unfortunatly everything you have got from the breakers is useless.
You are going to have to find the parts from a half canbus car and the same Airbag ECU.

Why are you doing this anyways? Did all your airbags go off?
