Error codes 2c58 and 2c86

[jtriana]

Hi all. I did an oil change and spark plug change, both OEM, last Thursday and when I started the car it went into limp mode and threw error codes 2c58 and 2c86. I have checked and rechecked the intake and all vacuum lines, as well as replaced the boost solenoid and MAF sensor, but the errors keep coming back. I also checked that the oil filter housing had the middle insert and it does. What else could I check or what could be the issue?

2013 135i N55 with upgraded FMIC, charge pipe and VRSF catless down pipe. I have also been running MHD Stage 2+ for a few years now.

Well since you have the codes, have you done any research on them? That could be a start? 🤔

Of course. Which is why I noted what items I have checked and parts I’ve replaced.
