P0413 code

[KingOfSpades007]

I've been dealing with a P0413 for a few months now. It would come and go randomly. I finally took a look at the combi valve last weekend and ran tests through OBD11. Both the solenoid and pump tests worked everytime no matter how much I wiggled the cables / connector. Only been a week but It hasnt come back yet despite ~500 miles and multiple redline pulls. Like you said maybe my connector or sensor was just loose. Probably unrelated, but I also cleaned my air intake filter and SAI filter the same time I played around with the Combi valve connectors.

Knowing my luck it will come back this afternoon because I wrote the post.

I had the same observations when I was troubleshooting this issue. Valve actuated no problem with no end of wiggling wires from me. Monitoring the pressures when the pump/valve are on/actuating, they seemed pretty constant, which suggested to me no leak or anything like that.

I hate parts-cannoning things but that's what I did and bought the 06K131097AA kombi valve and it's seemed to have done the trick. I have the old one sat in the basement and thinking about dissecting it, but really I don't expect to see anything glaring.

In your case, if it's not coming back relatively quickly, I'd think that the connector may have been loose??

Well it lasted about 11 days and the CEL came Back. Got the usual P041300 and a new P049100 - SAI system Insufficent flow. I am going to suck it up and have the combi valve replaced next week.

A few weeks have gone by....no codes, no CELs. SAI is functioning correctly. Loose connector on that combi valve was it.

I bought a new SAI combo valve back in January and took my car to a shop to have replaced. They disconnected the plug and found it was covered in soot. They cleaned the connector and told me to wait and see. No issues for 6 or 7 weeks and then out of nowhere it came back today . I already returned the new combi valve fml . I was at the track last weekend so maybe it got extra dirty again?
