Hard start, rough idle, drove 3 miles, check engine light turns on, code: p0021 bank1/2. Did research. It's a banjo bolt filter/screen mine was cracked in half inside the oil line restricting oil to the turbo. Managed to remove one easily accessible banjo screen which fixed half the problem. The other bolt virtually not accessible by me. Almost all turbo vehicles from Subaru experience this problem as code: p0021 or just catastrophic turbo/engine/coolant failure.
