My 2006 V70R. 209k miles, has a check engine light that is intermittent going away for a couple of days, before returning. The only really symptom I notice is a slow loss of boost power where it spools well sometimes hits 18 but slides down to 15 or 14psi. The other intermittment issue is that initial RPM rev for the turbo sometimes doesn’t happen and the car begins with a nice 800-900rpm idle. Idle is smooth.
The VIDA report shows that out 250 + cycles about 55 have the MAF code.
Within the last year I have replaced the MAF sensor, and cleaned (and replaced gasket) on the TB.
Could this be the CBV leaking a bit ? I seem to remember and intake air code on my 850 turbo that went away when I replaced the CBV valve. Any insights or thoughts would be appreciated. I am sorry the readouts are sideways something with upload as the files are orientated correctly before I upload them .
I have attached pictures of the code and the frozen state when said codes were thrown.
