I finally replaced my combi valve again today. New PN showed up so i grabbed it. 06K-131-097-AA A little more expensive than the older one, so i hope it's "different"/"better". Ebay seller had it for like $300, so not as bad as MSRP dealership had it at.
Also, might harass the pressure sensor if it goes again next time. 06k906052 is the little inline guy. Maybe he is throwing this damned code? Super easy to get to.
Regardless, i got a readiness issue from turning the code off in Maestro. Didn't care to waste an emissions/inspection appointment with that and the cat not ready, so i bit the bullet and bought the new revision combi.
Emissions test on Tuesday. Wish me luck.
Here's a few pics of the location of the valve as well as the new vs old rev, and the pressure switch (my next target if the CEL returns)
I’ve replaced the valve as well with the older revision and the cel came back for me too. It lasted a few months though. Let us know how the new revision one works. Did your car seem to lose power when it was throwing the p041300 code? Mine seems to. I was told by a vw tech that if it persists then the engine harness may need replaced. Worst case scenario that is, but he’s replaced a few for this reason.
Getting a regular (daily) CEL for P041300 (secondary air injection switching valve A open) as mentioned above. Visual looks fine w/r to wires etc. to the combi valve, nothing unplugged or damaged that I can see. SAI pump and combi valve both work when I run the output test using OBDEleven under the engine control unit/output test with the key on/engine not running. When I run the basic settings for "checking secondary air system" no noises and it never finishes so not sure what that is really doing. All of this started after cleaning/re-oiling my air filter/SAI filter (certainly can be 100% coincidence) but is it possible that the pressure sensor on the combi valve is the culprit and became contaminated?
