I’m getting a service engine soon increased emissions light. Anyone know what screenshot means? Is it CCV PCV causing it?

 

You have a vacuum leak. I would do a smoke test to pin point it. If you have not changed the PCV system before plan on doing it also if it's not where your leak is. I would recommend to not change one part plan one changing them all because if they are old you will break a hose replacing just one piece.

You didn't post your year and model so I can't help you any further

 

2004 525i 215,000K miles

PCV was changed 9/4/19 at 187,000 miles. Intake boot and fuel injection idle air control valve gasket was genuine everything else OE or Rein.

 

Just the PCV and not the whole system? I would do a smoke test and proceed with what you find. If only the PCV was replaced there's a good chance the tubes are your corporate or the intake boot. I am not suggesting you just change parts. I am suggesting you diagnose with a smoke test first then go forward.

 

It was PCV kit from fcpeuro. Smoke test was done 2 times there’s no leaks. I’m going to replace PCV kit again.

 

Is it possible to pass a smoke test but still have a vacuum leak?

 

If it's done correctly then no. If there is a noticeable leak you will see smoke.
