I have a '10 335i with 82k miles. Fresh plugs and coils.

Only mods are a VRSF charge pipe w/ factory DV's and a Stage 1 MHD map.

I'm throwing the following codes. CEL only pops under ~ 75% throttle. SES is persistent.

29CD - Combustion misfires, cylinder 1.
2C3F - Oxygen sensor before catalytic converter: Signal lines.
2C9C - Oxygen sensor heater before catalytic converter: Activation.
30FF - Turbocharger, charge-air pressure too low.

I was going to order a new o2 sensor but I read a few posts that seem to imply it may be more complicated than that when combined with a misfire.

Any input is greatly appreciated.
