I found a thread saying that if the seals of an injector were damaged blowby could end up in the return fuel line. I was wondering where the blowby would enter the return line? Are they talking about the seals on the outside of the injector?
I heard my aux pump struggling and opened my fuel filter up to find it full of what looked like black soot with little chunks. I just bought the car but believe the fuel filter was changed a couple of months ago.
I drew some fuel from the tank and it's clear and I have a bit of black death blowby buildup on top of my engine. The black death isn't cooked onto the engine top and comes off easy. I've included a picture of what it looks like below.
I swapped the filter and the pump sounds normal but the car runs terribly. I'm thinking dirty injectors. I didn't wait for the car to warm up because I didn't want to further damage the car if it's circulating soot through the fuel system but with the coolant at 25 degrees celcius I got these readings.
Idle Stabilization Injector Quantity Deviation:
0.40 mg/str
-2.19 mg/str
1.29 mg/str
0.52 mg/str
Also wondering if I can take the injector apart and clean myself? I think the turbo is blown, I have the p2015 manifold code and the DPF clogged so I want to see if I can get the car running better before I spend lots of money so if I could even get them to improve a bit with home cleaning it would be useful to know if throwing money at the injectors would solve the problem.
Also what is the best way to flush the return line?
Would changing the seals on the injectors, flushing the return fuel line, cleaning the injectors and putting new seals on the injector plates (https://www.parkautomotorsports.ca/...-audi-tdi-8p-a3-mk6-jetta-golf-fiik-mk6tdi-kt) fix the issue?

I think I ran the car with low oil after the turbo exploded and I wonder if that's what damaged the fuel injector seals.
