so today on the way to practice the car threw these two codes: AWD 77, and emissions P0172.
I've seen others with the 77, but has anyone had P0172?
Last two days the car sounded different to me... like the intake hiss was lasting longer into the RPM band almost. I almost wondered if the variable turbine inlet was staying closed and constantly bleeding off boost? I didn't notice a difference in power, but it did not seem to operate exactly like usual. A few times at shifts it almost felt like issues with the BPV/compressor shock bouncing back from a throttle plate.. I was thinking to myself that I needed to pull the IC cover off and start looking at potentially sticky BPV, or see what I see as far as anything like that, leaks in the intake tract etc..
Now today the codes popped up. Checked the oil when I got home just now. seems to be plenty in there.. guess tomorrow I'll try and take it in.
