Need a Bentley Manual for CEL

[jr_scheiBe]

Anyone have a Bentley Manual for a B5 A4 1.8T? I'm throwing this fault code:

P0411

Sec.Air Inj.Sys. Incorrect Flow Detected



Input as to what I'm looking for would be great. Thanks everyone

Jon

I get that code when I don't have my combi valve hooked up.

Check your EGR system. It could be anything from a bad wire on the solenoid that opens the valve to a vacuum line crack to the smog pump not functioning properly to the combi valve going bad.

Its a pretty simple system. I can point out all the part to you at the next GTG if you'd like.

That vortex thread is for a different engine, but similiar problem.

The vacuum line to the kombi valve goes bad all the time. Check the hoses that come off you intake manifold. There are also some hoses and valves under the manifold right by the throttle body that should be checked too.

The factory vacuum hoses get very brittle and/or shorten over time. They will shrink enough to the point where they pull themselves off the nipple of the manifold.
