SOURCE: 1997 VW Passat trouble code

Hi ejj509,

Both my 97 Passat and my wife's 99 Passat were throwing the same OBD codes you listed.

Both VW's had the same problem. There is no "quick" solution for the problem. I can tell you what I found, what I had to do and how I repaired both vehicles so they no longer throw this OBD error code.

I removed the black plastivc AIR pump and found that three of the six aluminum rivets which hold the AIR pump impeller housing together had rotted off so the case was leaking air. I went to a hardware store with one of the aluminum rivets I had removed from the AIR pump and bought six brass machine screws and brass nuts. I gouged the aluminum rivets out and replaced them with the brass machine screws.

After I had replaced the AIR pump in the VW, I cleared the codes and ran the diagnostics again.
It still threw the same codes!!!

Next, I removed the plastic top engine cover from the VW engine (VR6) and located the many air solenoids hidden under the cover. I went to a local NAPA shop and purchased an eight foot length of their smallest gauge neoprene gas line (1/8 inch ID).

I carefully removed each piece of rotted VW vacuum line from the air solenoids and replaced each rotted section with lengths of the new neoprene gas line. I had to follow out each of the old vacuum lines and replace them because they were badly deteriorated. This took about five hours to accomplish.

I replaced the plastic engine cover and connected up my cable from my laptop to the VW's computer port, cleared all of the codes and ran a new scan. This time the scan was clear! Woo Hoo! Apparently, the problem was both the leaking AIR pump and faulty, deteriorated (cheap) Volkswagen vacuum lines.

It was well worth the effort. My driveway has now become a bonafied VW repair shoppe.

I am getting 2 fault codes on my 2002 Passat they are P1296-manufacturer control fuel air metering and P0411-secondary air injection system incorrect flow. What would be the symptoms and fix for these...


I have a 2000 Passat (1.8T), and I recently had this code (P0411). First thing I did was to clean the mass airflow sensor (MAF) and reset the code by disconnecting the battery. Unfortunately, the code came back. It also came back with P1426. It ended up being the purge valve ($60 at ECSTuning, $140 at the dealer...I went with ECSTuning). Before you drop money on the part, inspect all of the hoses to ensure they are not cracked or torn.

Engine light on . fault code p0411. air solenoid stuck shut. show


P0411 Secondary Air Injection System Incorrect Flow Detected
p0411 is a generic code, probably a vacume leak,vacume hose broken check this first, check the air pump turn on the car but it needs to be cold, you should hear a high pitched whine, this is the air pump running,there are 2 hoses one suction one blowing thishose should be going from the air pump to the air cleaner disconnect that and see what the volume is should be pretty strong.
But mostly you probably have a broken vacume line somewhere

P0411 code 99 Passat


The secondary Air Injection system, this is basically an inspect and replace broken hose detail. Leave the inlet hose disconnected and start the engine. Listen and feel for exhaust hissing at the check valves.The check valve(s) will make like a gurgling sound as air is drawn in However , if exhaust is felt or heard replace the valve. Hope this works out for ya.
