B58 p112f CEL after changing pcv diaphragm

OddCore19 · 01-13-2024, 04:41 PM

My 2017 f32 440i had a PCV failure around Christmas, and a couple of days after I did the fix the CEL came up. The car drives perfectly fine, with no rough start/idling, power and torque feels the same. But the p112f code just stuck around. I tried clearing it with a scanner with no success. And I searched around for info on this code but most are n55 related. What can the culprit be? And if I bring the car to the dealership with the extended warranty letter for B58 PCV, will they cover the costs since it's caused by PCV failure?

First, you need to get it scanned with a BMW code scanner. P codes are generic codes. Then go from there.

Checked the code on bmwfault.codes and with my ecu variant considered it should be 101F01 or 101F02 (calculated air volume implausible). So I'm guessing it's something with the MAF sensor. Shouldn't be a leak since there's no eerie sounds or noticeable power reduction.
