My 2000 GLS 2.0L Beetle just had its check engine light come on. Hooked up to a computer it is throwing the code of
P0411 (Might be PO411)
Secondary Air Injection System Incorrect Flow
It this my Pre Catalytic o2 sensor gone bad. Is it expensive to fix? Can I do myself or my boyfriend? I am using gas like crazy. I just need to know what is it and if/how to fix it.

I Have family in Vw/Audi?Porsche dealership who can get me parts at wholesale but it is still an arm and a leg for labor or diagnosic on my car.
PLEASE HELP ME OUT! Gas isn’t cheap to be going though so quickly and getting ready to move for college.
YES MY TIMING BELT NAD SUCH HAVE ALREADY BEEN DONE!
Already been taken to auto zone and that is the code they gave me what is it just dont know which sensor it is!

AutoZone will run the code for free and tell you what it means.
They are very easy to replace especially the pre cat. It just screws into the exhaust manifold which is on the very front of your engine and behind the radiator.
The other O2 sensor is after the cat and a little harder t reach because its under the car but still just screws in to the exhaust.
These are the solutions from my volkswagen program that comes up for the p0411 code:
* Check Fuel Pump Relay (J17)
* Check Hoses/Pipes to/between Components
* Check Secondary Air Injection Pump (V101)
* Check Secondary Air Injection Pump Relay (J299)
* Check Secondary Air Injection Solenoid Valve (N112)
The problem is not your o2 sensor. There is a specific code for it. All of what is listed above is what you need to check. I have the computer and all the diagnostic programs for vw/audi and have been doing this for over 10 years. Sort of a hobby and at the same time saving a lot of money by doing it myself. Hope that helps you out.
I just read the code and its says:
Secondary Air Injection System (B2) - Incorrect Flow
or Secondary Air Injection System Incorrect Flow Detected
You can fix that o2 sensor for not much. Ask the auto zone, or call down and get a quote. Putting it in isn’t hard. That might not solve the problem. You might have vacumn hoses or something wrong to make you use excessive gas. Those nice little lights are only indicators of a system thats not working properly.
I have the same problem with my 1.8T jetta. Seems the secondary air pump, combination valve are bad, and or the hoses in between may have cracked ( they are usually a hard brittle plastic). it may start making a high pitched jet engine noise before long as mine has. not a cheap fix
