no , what module keep all exterior lights on after accident? which system can I use for faults? I tried obd reader not doing much .which module needs to be replaced after airbag deloyed? all the original modules are still in the car .which module prohibits me from turning the car on?
BMW Mechanic: Steve, BMW Expert replied 2 years ago
I will provide an honest answer. I trust this will be appreciated on a Saturday. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
I would suspect the sbsr module is likely the culprit, but there is no way to know without a BMW factory scan tool.
there are about 60 modules on this car and many of them can prevent start... plus, you can't just replace any without having them then reprogrammed.
an obd scanner cannot be used for this, a BMW factory scan tool or equivalent is required. if you do not have such a tool, unfortunately you will not be able to diagnose or repair the issue, or carry out necessary programming after replacement.
if you need a non dealer option for this, check out www.bimmershops.com or www.bimrs.org for options.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.

my last question would be, would the sbsr activate all headlight and tail lights? or is the reset when you clear faults?
BMW Mechanic: Steve, BMW Expert replied 2 years ago
Please do not forget to CLICK ON a positive rating
the light issue might resolve with a fault clear, but at the least should be revealed with the fault scan
it is most likely an issue with the lamp module - a fault scan will verify.
