I can monitor cam sensor realtime with my scanner. I don't know if I can with the crank sensor but that would be very helpful.

Do you use INPA or INSTA as a means to do that?

The "catch22" is that you won't get a code until you get a start from my understanding. But look into immobilizer, because it comes up on the forum regularly the EWS gets out of sync and allows crank but no start (why allows crank the world may never know)
EWS = Elektronische WegfahrSperre

If the rolling code sync between EWS and DME is lost it's lost permanently until initialised again with diagnostics. This can't explain temporary non start symptoms (cranks but won't allow fuel injection).

(If we were talking about temporary symptoms where the engine is not even cranking a problem on EWS module key recognition and start motor activation is a different thing.)

EWS 3.3 bedtime reading.

Solid point on the sync. Can't be ews sync but can be a bad key or a bad key antenna.

Do you have alternative keys to try?

Like I said earlier if there was a problem on EWS key recognition the engine would not even crank as starter activation would not be allowed.

I got it to start. And it idled for about 3 min and it died. I could not get it to start again. But when it did idle, it was idling rough. Before this, it gave me an error code for the throttle potentiometer 1 and 2 and one with no number next to it. Codes, 000075, 000076, 000077. One for the pedal travel sensor, potentiometer 2 (0000E8]. And 000073 - hot-film air mass flow sensor. Learn function, lower stop, throttle actuator (000086). I wanted to up load the pictures so that you can see what I see. But having an issue doing that. Hopefully this helps.

That's a boat load of errors most having to do with throttle.

If you can bring up realtime values, check on the gas pedal signal (both) and the throttle position (both). If the car can't read the tps I'm sure it will just pull the plug on running.

What's going on with the Alternator? If you can't get a stable voltage it can cause similar symptoms.

Feels like there's wiring loom damage check on the wiring from the TB that joins up and goes to the DME. Often when you get lots of different systems having errors it's a wiring problem.

I always thought that's how it should work but I hear tales of people trying to start with ews sync problems and say it cranks.

When I recently bought two new keys, I tried the valet key and it did nothing the first try. Second try it started the car. I would expect of any ews problem no crank at all but I hear of cases where it cranks but no start.

I also must say this. I didn't mention it earlier because I didn't think it would matter or make a difference. All the while I'm doing this, I'm jumping it with my truck because the battery that's in it has a bad cell. So it's just a bad battery.
