Haven't had the time to deal with this due to engine issues.
I'll give another scanner a go in order to get a more precise error on this problem. If I understood correctly, then in case the front door airbags deploy, the crash details will be stored into the module, which will need replacing. If that's the case then I'll have a look around in the local scrap yards, I've found plenty 2nd hand modules on sale for low bucks.
I've also heard that it might be not possible to deactivate driver's airbag and I'll have to get a replacement airbag anyway..not sure if that's true.
