W205 Strange airbag fault code B280613

[lukemc15]

Hi Guys,

After finally fixing my 2019 c180 c class I have this strange airbag fault code which I cannot seem to find any info about.

The code is:

B280613 "The squib for the refrigerant accident safeguard 1 has a malfunction. There is a open circuit"

To my understanding this is relating to releasing the AC gas in a controlled way after a accident but I could be wrong.

Can anybody seem to help me with this as I am searched the WEB for hours and can only find very little info about this.

What parts need to be replaced to finally get rid of this code and where are they located?

Thanks so much

There is a small fire extiguisher that discharges close to the turbocharger in the event of an impact. The idea is that it prevents a fire if the r1234yf refrigerant hits the hot turbo. If you look at the turbo you’ll see the silver braided discharge tube. Follow it back and you’ll find the unit you need to check. It’s usually at the back of the engine bay near the bulkhead
