I've had an airbag light on my 2002 Jetta for about a month now and I just got a vagcom cable. I hooked it up and read the fault codes thru VCDS lite and got airbag code 01224 - Control unit does not match vehicle. It also read an engine fault code 18017 - Crash Shut Down Activated, which is linked to the airbag control module. This would all make sense if I had been in a crash, however I have owned this car since new and it has never been in an accident nor had the airbags deploy. Any ideas on what could be the problems would be greatly appreciated!
