Fairly common.

More get dirty but they also fail. Neither would surprise me.

I know I'm late to the party and this recommendation is also potentially late... I know on my S-motor I replace the micro filter on my Vanos unit roughly once a year. It's super cheap, super easy to do, and I know a few people who have had a lot of luck with that preventing Vanos issues.

Well I went threw cleaned everything rest the codes. Drive about a 175 miles and SES light comes back. Plug in the scanner and it's the secondary air bank one and secondary air bank two. I have replaced the smog pump. Checked the evap valve with a vacuum pump. It was between 15" and 18" of vacuum so that's fine. So I then checked the vacuum control switch. No vacuum. Replaced the line and the switch. Still no vacuum. So next step was I check to see if I was getting power at plug for the vacuum control valve. There was power at the plug. I then tested the valve it self ran power to the control switch and the valve opened. I blew in one end air came out the other. Then I put it all back together and check it again this morning. Still no vacuum. Yes I check the fuses. Any help would be great. Good thing no more cam sensors check engine light.

Standard protocol is to send donuts to those in the thread that contributed to a diagnosis
Alright sounds fair

Or get lost and eat them yourself

Are you checking for power by grounding it through the circuit?
No, you dont get any donuts

No exactly sure what you mean. Grounded to the chassis or to the plug.

I just took everything apart and put it back together. And the vacuum line was pinched on the valve cover everything is working correctly now.
