Golf IV / Jetta IV :: Error Code P0411 - Car Won't Triggers Quickly After A Reset
Sep 29, 2015
Whenever P0411 triggers for me, it is very late into driving (i.e. like 30 minutes into the freeway type of situation) where the engine has already hit optimal temperature. I've gone 1000 miles after reset before it triggers. Sometimes 200 or so miles, but it never triggers quickly after a reset. I'm unsure if it matters, but the VR6 does have a cold air intake (and I do have the breather hose connected & maf correctly connected). I'm pointing it out because p0411 became an issue about 500 miles after I had installed the cold air intake.

I have a 2005 Jetta 1.8t and the thing will not start! The battery is fine, and has been recharged 100%. The fuel pump is pumping. It cranks all day, but just won't start. The only error code i'm getting is a P0411 which I understand is a leak in the vacuum system somewhere.

I keep throwing a P0411 - Secondary Air Injection System error. My previous pump was seized so I replaced it, and broke a few of the chintzy air hoses in the process. Now, with new pump installed and new air hoses connected, I can go about 5 days before the code comes back on.
So to recap, I have:
Replaced the air pump
Verified the new air pump functions, yepReplaced the air hoses
Verified connection of air hoses at all junctions
Checked the Secondary Air Relay for function
I have not yet checked the solenoid - unsure how to do so.

Alright so my car is popping up 4 codes.
P0411 - Secondary Air Injection System Incorrect Flow Detected
P0300 - Random/Multiple Cylinder Misfire Detected
P0302 - Cylinder 2 Misfire Detected
P0303 - Cylinder 3 Misfire Detected
Vehicle: 1999.5 VW Jetta MK4 2.0L GLS (AEG)
The P0411 code I have had for a while now and I been lacking to fix it. I pretty sure I can get this fixed but it doesn't cause problems so I haven't paid to much attention to it. Anyways, the other day I noticed a puddle of coolant under my car so after checking it out, the water pump was leaking so I bought a new one and replaced the old one. However, during the replacement process I had to remove the timing belt and I accidentally turned the top pulley about 1 notch and didn't notice at the time. After putting everything back on, I turned my car on and the engine sound a bit weak so I ran for about 10 minutes around a couple blocks.
I instantly noticed that the car had no power and it took me a long time to speed up. When I got back, I plugged in my scanner and I only had the same P0411 code and nothing else. After carefully reviewing the camera I had recording during the water pump replacement, I notice I had turned the top pulley a bit so I went ahead and removed the timing belt, readjusted it, and it worked! I was excited that the car was working fine again. Soon after, I headed out to take a drive and noticed after 60MPH the car didn't have much power. The car still accelerates after 60MPH, but extremely slow. As soon as I arrived back home, I plugged in my scanner and that is where I seen the 4 codes. Now my question is what could have caused this? Could I have damaged something when I ran my car with the incorrect timing?
Things I have done so far:
-I checked to see if I left anything unplugged.
-I checked for any vacuum leaks
-I checked my oxygen sensors so see if I was running rich/lean
Things I will do after work today:
-Check the spark plugs
-Check spark plug cable for damage

Just installed a short Ram intake on my 2000 Vw Jetta 1.8t. Had the Intake for about 250 miles and now the check engine light came on. Just pulled the code p0411 secondary air injection system incorrect flow detected. Is this just cause there is more air going through the MAF sensor?

2004 VR6 24v ... I had another thread about my son's car stalling after driving about 20 miles and then running good again after letting it sit for a couple of hours. Anyway I changed the Crank Position Sensor and I have been driving it work and back the last couple of days so I am starting to relax that the CPS fixed that problem. Won't be positively sure for a while as the problem took a while to occur. So far so good.
While coming to work today the car picked up the P0411 code, secondary air injection system incorrect flow. When I changed the CPS sensor i unbolted a module underneath the car by the oil filter to get better access to the CPS. I did not remove it, just unbolted it so I could push it out of the way about and inch.
After putting it all back together and driving it for several trips with no stalling this P0411 comes on. Is that module I moved the Secondary Air Pump and could I have disturbed something. I will check it when I get home. How critical is that code. I read where it works to warm a cold engine. What effect would there be driving with that code?

I have this whistling noise that developed after re installing my stock airbox. Seems to have just started right after installation. Cant seem to pinpoint what is going on. I also had a error code come u p(p0411). 1.8t b5.5 passat ...

So i got a 98 passat sedan used and was told it read a p0411 code. The person at autozone told him it was a cam sensor. The sensor was replaced. I know now from the manual that codes reads for sec. Air injection system , incorrect flow. It could be the vacuum lines. Now lets say it is the vacuum lines. Their is a misfire on cylinders 1-3.

I have a 4 door 1.8t AWW
Like I said in the title I keep getting the P0172 and can't seem to shake it no matter what I do. I believe the car is in soft limp mode as I can't boost above 5 psi. I'm also consuming oil fairly quickly (atlas 2 quarts in a span of 2-3 months), no smoke out back though. I did find that the whole PCV system underneath the plenum was wet, but nothing else was? Checked the PCV valve and it seemed operational and didn't stay open. Check PCV system for cracks and was unable to see any which added to the confusion.
Thing's I've done to try and fix problem:
-replaced breather hose because of crack
-went through all the vacuum lines and replaced where needed
-have two n75j's that I'm unsure if they work or not (is n75j the stock valve for the AWW?)
-cleaned the maf
-replaced valve cover gasket
-changed plugs
-replaced dv with splitter
Other things for diagnose:
-little wet around 2 of the injectors on top of the plenum (old o rings?)
-when running splitter full atmospheric I can hit 10psi but with it closed off can't get past 5psi

So finally got past the smog cert issue and a bad map sensor in the intercooler. However, during the smog test, I was informed I am getting low air pressure in the intake! What causes this? A bad MAF? a leak? I have replaced the EGR, and all rubber that connects hard pipes. The only piece not changed out during the rebuild is the plastic flex line from the airfilter box to the turbo intake.

Alright I might have made a major mistake and I need some input; I just recent bought a 2001 Jetta VR6 131k on it and at first I didn't notice so much but since I've gotten. To drive it more I've noticed it's really sluggish on take off and doesn't seem to shift into 4th gear. Also I started noticing a faint rattling noise. And the CEL is on with the codes P0785, P0411 and P1151.

When checking my check engine light , I got P0021 a cam timing error, but my mk4 Gti runs perfectly ??

Damn car is stuck in 3rd gear! Hooked up scanner and the screen just says error! I have to keep the scanner in the vehicle, hooked up, just to drive the car. That's just so it'll shift as its supposed to! Now it's not letting me pull the code out, in order for me to erase it! It just keeps saying "error".

I keep getting the error code P0420. Cat below threshold.
I have replace both the front and rear O2 sensors and we reset the check engine light. While driving through the cycles to reset the sensors for them to be ready for DEQ, the check engine light came on again.
I am about ready to buy the Cat Converter, but it is really expensive and if there are any other things that I can try before replacing the Cat I would like to try that first. Any other issues associated with that code, or should I just replace the Cat Converter as my next step.

I have a mk4 jetta 2.0l with about 130,000 miles. The issue with my car is that is has a rough idle and dies out completely when I put the car in neutral. I currently have codes 16839- EVAP system leak detected, 16487- Mass air flow sensor, 17978 - Engine start blocked by immobilizer, and 16795 - secondary air injection system incorrect flow detected. The secondary air pump was taken off the car before i bought it, so i do not think that code is responsible. Also all of my spark plugs and wires are new. I think the issue is either with my maf sensor or with a vacuum line. I have tried cleaner my maf and also unplugging it, and the car still has problem. Unfortunately i do not know where all of my vacuum line are. I have only checked the two the go into the sensor on towards the firewall. The one has vacuum, but the one coming for the egr valve did have any vaccum even when i tried with my other line on it. Im not sure if this is the issue, and if it would cause my car to die.

I was cruising down the highway and my check engine light came on. I was a few minutes from a auto store and they said my code was p1296. I found out it is either the thermostat or the coolant temperature sensor. I wanna know where it is located in the engine bay. I have a 02 VW Jetta 1.8T.

2002 Jetta 1.8L Turbo running fine. Then one day driving on the freeway at about 70, I try to pass someone and notice when I push the gas the engine lulls. I back off the gas and accelerate slower and I can get up to speed. Drive it all the way home and its fine a t low speeds. Turn the car off and try to restart it and it wont start. Turns over but wont start. No CEL or anything else, I check the codes and I have a P0171 (Lean fuel Bank 1). Where do I start? Also car is parked in an underground garage. No chance of a tow out of this place, it may soon be a Jetta tomb.

I just bought a 03 2.0 and ive been trying to fix her back up, she is almost there, just waiting on my first gear getter from diesel geeks and trying to figure out why these codes (p0420 and p0141) keep coming back on. Originally it was just a p0420 code so i took out the upstream sensor and cleaned it, then i took out the backstream and after examining it figured it should be replaced.
I went and bought a new one and replaced it, within the next 2 days the check engine light came back on throwing the original p0420 code along with p0141 this time. So i took out the new down stream 02 sensor and took it back to autozone and they swapped it out with a new one for me free of charge. So i put the newest 02 sensor in and then within 2 days, both codes p0420 & p0141 came back on. Two 02 sensor heating wires being bad i feel is a pretty slim chance. What is possibly the cause for these two codes repeatedly being thrown?

My car (jetta 2002 1.8t) have the error code p0501 even if the speedo is working. I replaced the speed sensor just to make sure.
If I erase the code, and drive no matter how far/fast I go, the check light doesn't turns on. But as soon as I turn of the car and drive again it does comes on.

My 2003 Mk 4 Golf have had a lot of error codes and I have cleared most (O2 sensors, thermostat, and Mass Air Sensor) I now have an error P0113 which is the Intake Air temp Sensor.
So I need to clean the sensor first then maybe replace it, but I can't find the sensor on the intake manifold.
I have looked all through the U-Tube info, but nothing matches my 2003 Golf 2.0L ...
