Hello all, My Skoda had a side impact causing the front passenger seat and curtain bag to deploy. Door was replaced and both airbags were replaced with guaranteed used ones from a breaker ( no airbags were deployed or flood damage to donor vehicle which bags came out off ). My scanner is showing the following fault codes and they return immediately after being cleared. 

B10051A   with comment, head curtain airbag igniter resistance to low.

B100A11   with comment, front passenger side airbag igniter short circuit to ground.

Do I have to have the headlining removed to check the wiring for the curtain airbag and what is the likely fault to these 2 'igniter' related problems.

 Not sure if this is related, though I expect it might be. When I start up, the engine will only rev up to 3k revs and no more. Have not taken it out on the road in case it goes into limp mode.  The scan only came up with the above 2 airbag fault codes, no others. Thanks

 

Hello, I think I have seen references saying that the airbags require coding - was this done?

Are you aware that engine revs are limited while in neutral gear?

Been there done that got the T shirt, bought mine as a write off due to airbag deployment.

 

I even panicked and asked the question regarding the 3KRPM rev limit (think it was 2.5K), that is normal and the wheels need to be turning even just at a crawl for the engine to rev higher.

 

Regarding the airbags you have 2 issues.

 

The airbags you have fitted probably are not compatible, one has too high a resistance and the other possibly a short to ground but could be too low a resistance.

 

Even with the correct airbags the controller will need to be replaced or you can have your old one sent away to have the crash data erased and its NVM reset, it could be that with that done these error codes go away.

Thanks for your reply FREEDOMLite.   It is a Kodiaq and the replacement bags came out of a kodiaq so I would have expected no compatibility issues.  Will have to get it looked at as I am wary of things possibly going wrong and bags deploying when working at them. I was hoping it might have been a wiring issue.

Regarding the control unit, I was hoping whoever was going to be doing the diagnostics, and work, would possibly be able to erase memory from control unit. I did not know the control unit had to be sent away to have all memory erased.

Thanks for reply Warrier193.  No, I was not aware of revs being limited on stationary vehicle. That would explain no other error codes apart from the 2  relating to airbags. Good news for a change which I will take any day.

Regarding coding I am not sure. I deleted fault codes only for them to reappear  with the information I gave in my original post.

I have seen in other posts that airbag faults are latching type - I'm not sure, but VCDS or OBD11 may not be able to clear this type of fault. Hopefully, other readers can advise.
