Technical Barchetta air bag light and fuel injector light coming on simultaneously.

Did they appear simultaneosly? If so, the only thing that comes to my mind is the supply voltage. Alternator, dead battery or a voltage regulator?
Reading the fault codes will help, if you have the possibility :)
 
They both come on simultaneously when the engine is started and stay on. Occasionally they both clear for a few minutes again together.
 
Weird, airbag light should not clear at all by itself once the airbag ECU has registered a fault. But these to lights do not have a shared connector at all (see page 37 in the wiring section of repair manual - if you don't have a copy, PM me).
And the bulbs are not next to each other in the cluster, but you might want to check the back of the cluster for anything that might cause shorts. But my best guess would still be the supply voltage.
How old are the battery and the alternator?

The battery and alternator are only a couple of years old. When I checked with the fiat service they said I should change the fuel injector sensor but I don't see the connection with the airbag warning light. The engine works perfectly, no stutters or reduced power and no other problems that I can detect. Only this one annoying fault. I do not have access to the repair manual perhaps you could send me a link??? Thank you for your help.
