Hey Audi Fam!!
I have a good question for you! I appreciate any suggestions....
I have a 02 b6 A4, Stage II 23psi, big injectors, GFB BOV and so on....
When I drive normal, barely boosting, car runs perfectly fine. When I come to a stop, idle is a little rough. When I punch it from stop, car will take off fine and boost 23psi for a sec and then make a loud klacking noise and suddenly loss of boost and power, Engine light blinks when the klacking noise is happening, but when I let go of gas, klacking stops and engine light stop blinking and stays on steady. I plug in my OBD tool and it read codes 304, 302, 300, which is cyclinder 4 & 2 misfire and multi-cyclinder misfire, I would think its the ignition coils but ive never heard this sound before when they went bad and my car threw those codes. Also when I boost, no smoke behind me.
My question is: If I had a blown turbo, wouldnt my codes read something else about the turbo or can a blown turbo cause the cylinder misfires??
Could it be my BOV??
And how are some ways to check if the turbo is blown??
Thank you in advance!!
