BMW Restraints Wiring
The question is often asked, "Can supplemental restraint system wiring be repaired?" The answer is: it depends on the vehicle maker. Let's take a look at BMW position on this subject.
Per BMW service information: "Only repair those cables which show visible signs of damage. In the event of visible damage, make sure there is only one cable repair in effect after the repair work. If no visible damage can be identified, the entire cable must be replaced. When carrying out repairs to the airbag wiring harness, you must use the spare parts offered in the Electronic Parts Catalogue (EPC)."
