Hey guys and girls.
This is my friends car, that unfortunately had broken down on the way back to Maryland.
Trying to help my friend out with diagnostics, and coming up with a game plan for getting this 335d back on the road.
I've ran the codes using Rheingolds software and it began with the high pressure turbo malfunction.
Following a smoothness control codes for cylinders number 6, 5, 1. (Engine still firing in sequence, but lacking boost.)
Then low pressure turbo malfunction.
Then a misfire on a cylinder number 4.(Now the injector on #4 had already been malfunctioning prior, so possible the detonation didn't occur?)
I'm thinking this could lead to an engine failure. Bending of a crankshaft? Scoring the cylinder wall? Slap from the valves?

Small squirt of oil from the Valve cover CCV. Coolant doesn't seem to have any oil in it. At least not the reservoir.

I'll post some code screen shots later. But what are your thoughts on this?

I'm thinking turbos for sure. But how can you be sure the engine is okay without digging into the headgasket scenario. I understand the compression test is probably a must at this point.

Anyway your thoughts? Yay or nay? Shot to shit?

Why is the font so big?

You can check for play in the lp turbo by taking off the intake piping

That's the plan.

What was the prior injector 4 malfunction? If the car is starting but running rough I vote fir injectors.

No visible damage on the low pressure turbo compressor wheel.

Pulled the injector off Cyl 4. And took some pics with an endoscope.
Looked okay for the most, but wtf is that one part?

I couldn't get any better shots of that one part of the piston.
