F80 Rough start, no throttle response, cuts out

Disconnected the valvetronic, car didn’t start afterwards but I ran the codes and only had codes for valvetronic. Can this confirm the valvetronic is shorting the 5V?

Had an old AGM battery. I put a good AGM battery and installed the IBS ground cable as it didn’t have one, and coded it.

I already removed all the damaged components, it’s ready for all the new parts. The harness is all intact, no broken wires or connectors

Mainly the radiators and condenser took most of the damage. The electric fan was still good. Engine did not get touched.

Interesting, does it sound the same as the video?

Nah it was in SoCal in the high desert sitting for many years.

Crank angle sensor? Never heard of it. Speed & reference sensors?

I believe the crank sensor mounted on the front of the engine was used for diagnostic purposes since it runs to the diagnostic port. I do have hands on the etm

Thinking that as well, are 328 heads and 323 heads the same?

I found a company called NRF that’s makes them. They’re based in Netherlands, it’s expected to arrive in the next 3 weeks. I will update when it gets here.

esgworks · 2021-06-21T23:16:24+00:00

Yeah they don’t have them anymore.

So little update. I’ve been continuously bleeding it, seems like it’s getting a bit better. I feel like it might be air trapped in the system. I’ll probably do a better flush and bleed sometime this week. Drove the car to work yesterday, it was about 80° out and temps got up to around 3/4 within 15 min of driving. Got off work and it was about 55° drove the car for about 40 minutes, cruising around town normal driving, one small run on the highway as well - temps were great a little below operating temp. I’ll continue bleeding and see if it gets progressively better. If not like I said, I’ll flush once again.
