Fiat ducato air bag warning light is on…..AGAIN.

[Camper634]

For the 3rd time in less than 12 months the air bag warning light is back on the dash.The last time was 6 weeks ago when it cost me £88 with crashdata to have the module reprogrammed.I did ask the question then why has it gone again.One of the replies it could be high voltage when starting the engine.So every time since the last replacement i have turned the ignition to on and waited until the various lights went off before cranking the engine.This morning i only tuned the ignition on to check mu LPG levels and almost immediately the air bag light came on.
I am at a loss what to do next.I cant keep paying £88 God knows how many times.Has anyone please got/had this problem and found out a reliable fix?Any help greatly appreciated.

I used these people, Unit rebuilt and guaranteed. My unit was failing annually.
SORTED
No proxy alignment needed.
Used by the motor trade to sort out various electronic ECUs

I can second that, as that's the company I used to wipe the fault code and clone my original airbag ECU to the new ECU that I bought.

We got ours from Coastal Motorhomes 18 months ago £180, with a 2023 build date, proxy aligned with multiecuscan. I added an extra earth wire to the module, an extra earth from the engine to body, wait until the airbag light goes out, pray then turn it on. Seems to be working so far

My part number was an expensive one. Went to shop4parts. Great service from Mick. Had to proxy align using mes, but can now use the software for a host of other stuff!

That rings a bell as it’s just what we do!

Our air bag warning light has been ignored successfully through 5 weeks in Germany.
Today it went off. Then turned on. And repeated this maybe 20 times.
Unfortunately it is now annoying as it beeps when the red light comes on.

Probably a wire somewhere but ecu multi scan arriving at home when we get there
