No start, error codes, need help troubleshoot

[camido62]

Dear all, this my first post since joining. I have a 2005 545i with SMG. After one morning of “no start”, the car sat for a while which drained the battery. I have now charged the battery to 100% and it is being maintained with the trickle charger so I can performed diagnostic. Using a Foxwell NT520 I retrieved the list of code below. I am very handy but need help and guidance with understanding and how to proceed by elimination to fix the various codes. Someone please help!

To many faults clear them all and start over also just because you charged the battery does not make it good, how old is it and did you load test it

Does it crank at all?

SMG problems can stop the starter from cranking.

No it does not crank at all. I do hear some clicking noise, which sounds like it is coming from the passenger side

Clear the codes and re scan. Those remaining are hard faults, which indicate faulty wiring, sensors, and/or dead and unresponsive control units.

I bet the battery is toast. That clicking sound is from the starter. I bet the voltage at the starter drops to zilch when you try to start the engine. That starter takes a bunch of power. Electrical power is measured in watts. Watts=voltage x current (measured in amps). If the voltage drops the starter tries to draw more amps to compensate. But the battery can’t provide the required amps. Have the battery tested for cold cranking amps.
