Passat (B5) :: Engine Makes Knocking Sound At Idle After 30 Minutes - Code P0411
I have a 2002 1.8T with about 75k miles which makes a harsh rhythmic sound at idle after about 30 minutes of driving. If I tap the accelerometer to increase the rpm and release it goes away and is silent. Recently it also seems to be making the same sound when it starts but goes away as soon as I drive. The sound seems to be coming from the front lower right (passenger side).
I have changed the timing belt about 18 months ago (along with the water pump, tensioner, etc. using an ECS tuning kit) and it ran fine (seemed even smoother than before) but it had a small engine oil leak which my mechanic fixed. I think this sound started after he repaired the leak. I've left the car with him for a week and he just called and said it he couldn't figure it out but it could be an oil pressure problem but I have not had any issues with an oil pressure light.
I have had issues with the P0411 code over the same and have replaced both the secondary air pump and the combi valve but the code just reappeared and my mechanic says he has checked the entire system again and can't figure out what is causing the problem. Not sure if the two can be related but just thought I would add that. The car runs fine otherwise and I have always used synthetic and the large oil filter but I am beginning to think this could be a sludge issue (the noise).

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.

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?

98 Taurus, 6cyl, 3.0L OHV, 184K miles. Check engine light is on and code reads "P0411 - secondary air injection system - incorrect flow". This is my son's hand me down car and has a rather large exhaust leak that I plan on fixing. Could this code be related ?? I found out that the CEL has been on for quite sometime now and the car is due for emissions testing (state inspection) in October.

My 1999 VW Passat has a check engine P0411, P0422, so I looked for any damaged vacuum lines and found one that was all melted coming out of the blue vacuum reservoir tank in the front left lower bumper area. The line was broken off and I cannot figure out where this line is supposed to go.
View 1 RepliesGolf IV / Jetta IV :: Cylinder 2 And 3 Misfire - Code P0411
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
Golf IV / Jetta IV :: Error Code P0411 Causing The Car To No Start
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.
View 5 RepliesGolf IV / Jetta IV :: Error Code P0411 - Car Won't Triggers Quickly After A Reset
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.

View 4 RepliesGolf IV / Jetta IV :: 2004 - P0411 Code / Secondary Air Injection System Incorrect Flow
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?
Passat (B5) :: P0411, P0011, P0300, P0301, P0303 - Misfire / Sputters And Hard To Drive
2002 Passat 1.8T
Backstory. The P0411 code shes had for quite some time. I think probably 4 years maybe. Just never did anything about it because I guess they are expensive to fix. Thats the SAIP and combi valve correct? Anyway to remove all the emissions stuff and get the codes deleted?
So, about 3 weeks ago, maybe a little longer i cleaned her engine bay, replaced a few vacuum lines because the shop she took it to last year did a terrible job. Mind you, they did a head gasket, timing belt and some other minor things while they were in there. And they couldn't take the time you run new vacuum lines, since they just cut the originals and used a bunch of t fittings to "solve" the problem.
Anyway, i replaced the lines and it seemed to run better at idle, still had a little mis at idle but ran smooth at speed. I also did an oil change, put some fuel injector cleaner in it, put some seafoam in the oil, and cleaned the engine bay thoroughly. I did it properly and took all the plastics off, cleaned them, scrubbed the bay and used an air hose to get rid of the excess water. Left in a nice state. Ran smoother, looked better, so on and so forth.
Fast forward to last week, and she mentions to me her car isnt running right. Its sputtering, hesitates, running rough, exhaust is puttering, and it used up a lot of gas. She parked it for a few days, and i came down to look at it. Mind you, i don't have a code reader. So I looked at it blindly thinking it had an ignition issue. Nothing could have changed that quick since i looked at it.
So, today we got one coil(just in case ones bad), and 4 new plugs (Autolite Iridiums). Replaced and gaped the plugs to .030, torqued to 23 ft/lbs and started the car. Seemed to run a bit better, but subsided quickly. I then pulled each coil harness plug to make sure it would misfire on each cylinder and it did. So, new plugs and the coils checked out. Time to get its codes read.
Took it to the Pepboys and the codes it came back with were the P0011, P300, P0301-3. Cleared the codes and they came back nearly immediately. I had the dreaded P0011 code. The misfire codes im guessing were from the coils being pulled on each one, and also due to the P0011. Now i read a lot of threads about the P0011 and how its usually not the camshaft position sensor. However, i pulled the plug on that while the car was running and nothing changed. So i thought it could be the CPS. Changed that out and still nothing.....
Passat (B5) :: Engine Code PO116 - Engine Coolant Temp CKT Range / Performance
I just had my 1998 Passat 1.8T with 97000 miles checked since the engine light came on. It started this afternoon and the car ran just fine. I took it to an Advance Auto and after they plugged in the OBD tool it came back with the code PO 116. Engine Coolant temp CKT Range/Performance.
The fellow decided to clear the code and then the car would not start. I waited for about 15 minutes and the car started with some hesitation and the light was out. When I got home I let the car sit for a few seconds and it started perfectly like nothing ever happened.
Does that mean that the temperature coolant sensor is bad??? I have a Hanes manual and apparently is not too difficult to do. Would I have to partially drain the radiator?
