CRANK, NO START Invalid signal CAS to SMFA? '11 740LI
Hello all, I recently acquired a 2011 740li from a family friend. It sat for awhile and cranks but doesn't start. I figured id give it a shot since it has the n54 that I have become familiar with on my 08 335xi. Here's what I've done so far.
Question is at this point- since I haven't found anything related to this code on the forum/web- does this code cause a crank no start? From what I understand if theres any invalid communications between cas and other modules the vehicle will not start, and cas-dme sync could remedy this BUT I CAN NOT for the life of me find the dme-cas sync funtion on either the fowell nt530 or ISTA+ installed from bimmerpost main thread. Maybe it being a 740"LI" has something to do with that?? followed multiple instructions but one was using an e90n54 and the other a f01 n63. I tried to be as detailed for anyone that can help or is in the same situation! Any progress will be noted on this thread. TIA |

Anyone have any idea what this code refers to? Going through inpa ive only found ecu reset for the cas, no dme-cas sync option. I would think reseting both modules then syncing would fix the issue but I can't seem to find any sync options |
Appreciate
