I bought an e92 from copart and it won't start. It was hit pretty bad but mechanically wise there appears to be no damage, the key was missing but I bought it from BMW, the steering wheel airbag and passenger airbag went off so I knew the bst cable went bad so I changed it and erased the code. But The car still doesn't want to start, there's no crank at all and I also got a new battery with a charge above 12.00. I also checked the cas relay with another e90 one and nothing. Does anyone have any suggestions?

do you own a diagnostic tool or software?

you need the codes from the car if you want any chance of sorting it out passed it being a battery wiring issue.

I'm assuming you checked for 12V to as least the jumper point under the hood and checked all the ground straps.

I would also suggest a diagnostic software. It would be difficult to identify the problem otherwise

See if it will start and run for a few seconds on starter fluid.

Does the replacement key at least turn the dash lights on? You state it doesn't crank the starter at all.
