Hello everyone, Thank you for allowing me in this forum. I just bought a 2005 545I manual transmission. I need help where to buy or reprogram a 2nd hand airbag SIM/SGM module aligning to my car VIN? I cannot proceed to my troubleshooting without this module. The car that I bought does not have SIM/SGM module, recommendation is highly appreciated. Thank you.

 

I'd suggest you check on eBay. Then use ISTA to code in the VIN.
