Floated 2008 BMW 328i no start and spark plugs for power but no sparks, I used Foxwell NT510 and read out fault codes, what I can do next? Reading the following parts.

Suggestion:

the DME (Engine Control Module) is NOT functioning, for instance 5th line says EGS (Transmission Control Module) can’t communicate with DME. Also I don’t see any indication of any code from the DME, either present or past. If your Foxwell has the ability to connect to the DME alone, try to get it to do that & see if it confirms that it CANNOT connect.

I would suggest trying to get the DME to power up. There is a separate relay that powers the DME. The DME itself activates the relay K6300 soldered into the JB as shown in this “Installation Location” link:

Here is the Wiring Diagram for the Relay:

Here are other relevant Circuit diagrams for the DME:

Finally!!!

I actually sent the ECU, CAS and 1 Key to the repair shop so they can test it but most likely they gonna get me another ECU and they gonna sync the CAS and Keys to the ECU.

Also I bought relays to replace
1 black for the ECU
1 black for the fuel pump
1 green for the wipers
1 blue (I can’t remember for what).

……

So, foxwell NT510 is a pretty good scanner for the beginner & DIYers.

 

Also, to troubleshot this 2008 BMW 328i, If you installed INPA or ISTA, then a K+DCAN Cable is what you need to connect the OBDII socket to your Computer USB port. And this cable at 16USD is suggested more than any other on this site:
