[imperial21]

Hi
Just entered my clio for its mot and its failed on air bags with a few other small things but i am really stuck on the airbags with what to do i have had a guy pop by and read the faults, it had P3507, P350C, DF077, DF068, Fault codes have been cleared but P350c still remains, Are there any bodges to get the air bag light to go out ? I have heard of resistors etc
