Hello I have an 2006 BMW e87 120d which I bought several months ago, yesterday while cleaning under the seats I noticed a cut wire which I traced to the seat belt pretensioner. That should trigger an airbag light no? I do have ISTA D and INPA but there are no airbag errors. Is it possible to somehow hide the codes from even appearing? Or check if the airbags would function during a crash? ( I did check the airbags and at least those are there )
