X5 Cranks but don't start
I had recently had my ecu flashed after getting too low on my miles to no start to do the driving condition run and to clear particulate filter. Before flash started and ran. I passed all the tests on scr functionality test and figured this was my best option. Now it Cranks but doesn't start. While reinstalling my ECU some wires. They are working fine. Says something about CAS control module issues. Had the ECU flash checked and is ok. Do I need to sync the CAS and ECU? If yes how?

Did the fuel system get opened at any point? Fuel injectors or fuel filter?
Most diesel no starts are a result of not fully bleeding the fuel system. |

No. No fuel work or lines opened. Had issues keeping the proper voltage at 1st until I aquired a battery voltage maintaining equipment. So thought was that at 1st. I'll attempt tonight to try again and.kist more details. Also get like 6 errors on the modules when the key is turned.
