This guy is the best mechanic I know. The stealership diagnosed my C7 Audi A6 and needing to get a new wiring harness total work to be done 15 to 20k. They even went as far as to offer me 200 on a trade! Came across Alex online and he resolved the issue for a couple hundred dollars. Will never go to a stearlership again

Thanks for easy listening fixed myself thanks to video. I'm learning how to fix everything myself and passing information on to others that take pride in learning and doing for themselves.

I have p0411 and replaced pumo and valve. The pumps get water in them and freeze. This fixed my valve stuck issue. But p0411 incorrect flow came back again. Not sure what it is

[@vtae44]

I went through this exact same sequence of getting the pump itself replaced (my fault for not getting the system cleaned out first), then getting the system cleaned out and I still have the engine light on for P0411. Did replacing the check valve work?

[@mitmaks]

You can open check valve and see if plunger is stuck. Most likely it is and it won't flow air at all. You can carefully pry it up and down and make sure it opens easy and then reassemble it. It should fix the issue

Would a 02 Oxygen sensor cause a P0411 ? I replaced the air pump and valve sensor cleaned all the ports from carbon wasn't much in there code still comes up P0411 HELP!

Good video Would this apply to the 3.6

Did getting new check valve work.... you never said.................

Can this cause my car to not crank up and power up? I went to auto zone and got the same codes. But when I tried to start my car up nothing happen and my key got stuck in the ignition. I can turn it but it won’t come out n it doesn’t do anything when I turn it

[@anrmobileservicellc1875]

Unfortunately secondary air injection system has nothing to do with starting the car or car running. Seems like you have an issue with the key or lock cylinder in ignition. I would start with that.
