Welcome to the Forum Lee,

My guess would be that the airbag ecu modules were not replaced. On Renaults i believe you need to replace the airbag ECU module and not reset them. So the person who carried out the repair probably just changed out the airbags and assumed that a simple computer based reset of the AirBag system would solve the problem.

If it was as simple as a reset that the seller claimed, then I dont understand why he wouldnt have reset before selling the car, as this will lower the value further. I can only assume it is purely for cost cutting purpose.

I know that VW's airbag system works like that and you can reset them. i've reset the airbag computers on some VW's in the past. But as far as I am aware, Renaults need a replacement airbag ECU.

You should try and find out if these units were replaced.

Hope that helps

 

On the later models if the air bags have been activated the engine won't start so it seems some type of resetting or such has been carried out.
When this occurs both the secondary restraint system computer plus the ECU have to be reset or renewed.

Obviously the car won't pass the MOT when the time comes so technically the car is unroadworthy which in turn may have insurance implications.

Sounds to me like an unprofessional repair.

Note - apparently there are online companies who can reset the control unit.

 

Thanks very much for the replies will do a little digging and see what i can find out, other than that it looks like a trip to Renault.
