Code P1505 PCV?
2013 75k miles 128i
Reading suggests a possible PCV valve leak which requires a new valve cover since the PVC is integrated into the valve cover. (who thought that was a good idea?!) A symptom is supposed to be a strong suction when removing the oil filler cap. I have that symptom but don't remember how it was when I did not have a code. If anyone with a good running N52 could try to remove the cap and let me know what it feels like, I'd appreciate it. Subjective, I know, but worth a try. Thanks!

Mine is an N51. The PCV valve was recently replaced under the SULEV warranty. With the engine running, there is light suction pulling the oil filler cap into the cylinder head cover and a small hiss of air when the cap is removed - nothing that I would characterize as excessive.
For what it’s worth, the PCV valve failure on my car was accompanied by an intermittent squealing sound, typically after lifting off of the throttle and coming to a stop at a stoplight. |
