SOURCE: 97 Jetta Secondary Air Injection System Incorrect Flow

the air pump is located on the engine towards the front of the vehicle and has apx. 3/4 diameter pipes running to and from it. it is apx. 2 fists in size and it is black plastic. one of the lines on top of the air pump runs to the other side of the engine towards the firewall. at the other end of that pipe is the valve. disconnect that pipe while the vehicle is running. no air out of the pipe means bad pump. air coming out of the pipe means bad valve

SOURCE: Code P0411 is showing Secondary Air Flow problem

The P0411 code you are getting with that SAAB is the SECONDARY AIR INJECTION CHECKVALVE 95% of the time. This sometimes will allow condensation to build up in the air lines
that run to the air pump and air filter. Its part of the emmisions BS that they put on these cars. The check valve is costly, its usually about $100 or more depending on where you live I guess but its
much cheaper than $600+ dollars plus labor for a new air pump.

In some uncommon instances this may not be the problem, but this is a known issue with the SAAB Q93 and some other models. Once replaced it should be ok for another 100,000 miles +/-.

Hope this helps as late as I am finding your issue!

SOURCE: I have a 2002 Audi A4 1.8T with trouble code P0411

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.

Check engine code

Check air pump , they tend to split casing , also check vacuum hose to EGR (combination valve) and valve itself.

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.

P0411 Secondary Air Injection System Incorrect Flow Detected, check the...Combination valve
...Secondary Air Injection pump motor
...Secondary Air Injection solenoid valve
I would take it to a mechanic

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
