Air bag problems 2009 Megane 1.5 dci

Hello!
I wonder if someone can help me with knowledge regarding my airbag fault.
Below is 2 error codes when I read diagnose. I try to delete both, but DF032 is back immediately.
I cant access airbag module with diagnose. I read this codes from instrument panel ecu.
All other ecu is not a problem to get access to.
I have checked fuses beside pedals and fuses beside battery in engine compartment, all seems ok.
Does anybody know where the airbag ecu is located?
Grateful if anybody can help me!
Thanks
Arne
