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.

What is code p0411 stand for on a vw 2003 new beetle


p0411 code is Secondary Air Injection System Incorrect Flow Detected. Google it, there are tons of VW forums out there. I would check your air pump, check all of your air hoses to be sure they aren't cracked or torn, try cleaning the mass air flow sensor, check your purge valve I had a friend that got that code and it ended up being her purge valve. Also try checking the vacuum hose to your EGR valve. Make sure to unhook the battery to reset the computer. Hopefully one of the above will work for you.

Obd code of p0411 on a 1999 ford mustang 3.8 v-6 what do I check to correct


That's s failure of the secondary air pump. It'll have to be changed. It's an emissions component meant to help with cold start emissions. It won't cause engine running trouble but at inspection time you'll fail for smog. Change it before then and you'll be fine.

2002 VW Passat GLS 1.8T throwing two codes: P0171 and P0411. No noticeable loss in performance. Can I fix this myself?


System Too Lean (Bank 1)

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.
