Hi

I have a 2000 A4 1.8T Quattro & I'm having problem with the check engine light & when I scan it the code was P0411 meaning Secondary Air injector Systems & Incorrect Flow Detected. A friend at the dealer told me that if I chang the "Camivalve" don't know if it's the right parts word but it sound like that Camivalve. I won't have the engine light on so my questions that Can someone correct me on the parts name & spelling & a pics of what's it look like. Also is it hard to replace if it's not too much a links with instructions on how to get the job done. Just trying to save a few bucks for the holidays


Happy Holidays y'all

Thank You

 

Check combination valve.

Repair Manual , 1.8 Liter 4-Cyl. 5V Turbo Engine Mechanical, Engine Code(s): AEB, ATW, Repair Group 26; Checking Secondary Air Injection (AIR) system

- Check hose setup (Secondary Air Injection -AIR- solenoid valve); check intake system for leaks (false air) Page 24-68


It is number 10 on the attachment. There are other possible problems such as cracked hose. Check the hoses, especially the hard rubber 90 degree ones above the turbo. They sometimes have hidden crackes underneath.

Be very careful with the area codes. They are a very tricky thing. Even one wrong digit can create huge problems. So it is better to properly recheck your postal code in case of some serious delivery or information https://areaphonecodes.com/united-states/213. With the growth of cities, a lot of changes to the codes are being introduced on a constant basis. So you should be aware of a potential discrepancy.
