Made a lot more progress today. First took off the million screws for the diffuser and undertray. Then got to work on the front turbo, another huge PITA. But I got it all out, the downpipe for this one was wrapped.
I got everything unplugged from the motor, took off the intake manifold, got the injectors out, etc. I think I found the ECU right on the passenger side of the firewall, so next step is taking that out with the wiring harness.
On coil #1 I found a bunch of goop, so either there was water that got in there, or maybe an oil leak from the plug seal on the valve cover. Will have to investigate later. Also found a bunch of grime below the front valve cover near the cam sensor, so I might need a new gasket there too.
