Dear customer, I would like to know if you have already checked the battery, fuses and immobilizer system, I would also like to know what events preceded the failure, or what happened?

Customer: replied 11 days ago.
I just checked the battery, shows 11.95 V when engine is off and 14.05 V when engine is running. I checked all the fuses , they seem to be OK. The car had no accident I was driving around Scotland when all of a sudden the warning light came on, I never had it on before so not too sure what happened

Dear customer, the number (13) talks specially to the code B1126:13: airbag module open circuit or high resistance.
It seems that the offside airbag is not working well, it would cause a replacement but first I recommend you to verify very well its connections, but just on the passenger side.
