Got CEL, DTC 16795, Secondary Air injection incorrect flow..>>
Had this before, thought perished vacuum pipe fix on combi valve would fix it, nooot! What is the most common thing that goes wrong/fails with this system: Combi valve, solenoid valve or air motor or connections at one of them? Experiences?
I have Bentley instructions but what simple tests should I focus on first? I cannot get underneath the car easily.
Where is the solenod valve located?

I think I had that same code...
not positive, but I think so. Dealer replaced secondary air injection pump under warranty. Not sure if that's the only fix. It's just an emissions thing when the engine is cold, I would probably just ignore it or see if I could trick it.

not nearly enough driving to reset readiness code
it can take several complete driving cycles to reset readiness code. By one complete driving cycle I mean engine completely warmed up, driving on the highway for dozens of miles.
You could use Vag com to more quickly set readiness code.
