Thanks for the info.
Is there any info on what all the values mean while using the REST button feature?

I did a search and couldn't find any.

I suggest you focus on the important data until your car is running correctly again.

The problem should be either battery/alternator or K40 relay failing.

I cannot find a module that looks like this anywhere in my car.
Where is it located?

My car will not start at all now. I cracked open the injector lines and there is no fuel getting to the engine.

Everything else seems normal except the front windows do not work as well as the seats but that problem has been there for a while.

The K40 is the front most relay inside the computer box on the right side of the engine compartment.

Open hood, open drivers window, turn key to pos 2. If you hear a click from around the IP area your shut off valve just openned. If you didnt, it didnt, and will never start. Either your K40 or your SOV is bad. Repalce the K40 first because of the other elect glitches you are having now.

Search "SteveBFL" and "AC diagnostics" for what all the other CCU results mean. Mostly pertains to AC temps, pressures, etc.

Ok. thanks..I found it by checking the part number. It doesn't look quite the same as in the picture.

I sure wish there were test points or wiring diagrams somewhere. I think knowing which wires went to the pump would make it be easier to diagnose.

This car makes me wish I still had the old 240D. It never left me stranded.

You could pull the plug from the SOV and trace back the wires if you wanted. Don't think it will help you any. Or, you could pry the cover off the back of the K40 and look for minute cracks in the PCB pathways that open and close with changes (epxansion/contraction) in temp. You'll need a good magnifying glass; 15 or 20x cause what you are looking for is "really, really" small.

Turning the key to pos 2 and *not* hearing the SOV click open when it is in a no start condition is much easier than either of the above...........

I replaced the K40 relay and the problem remains.
I did notice that while the engine was cranking there were some air bubble visible in the fuel lines that attach to the back side of the fuel filter. I took the fuel filter off and it didn't appear to be completely full.

With the injector lines loose it still doesn't want to prime. There is a loud click down by the injector pump when the key is turned on.

The windows and seats still do not work after disconnecting the battery for a few minutes and re connecting. This has always been the fix in the past.
