Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (GLX96)
Yup I have this. Does your car stay at normal operating temp? I find that if it's idling in the driveway, it will get to normal temp and stay there. upon driving, however, it dips to 180 or so and wont come back up.
Additionally, there is a sound like avacuume leak once it gets to 180 or so that sounds as if it's coming from behind the speedo cluster.
Because of the fact that it doesn't stay up in temp, I'm wondering if it's not a thermostat issue in addition to the air pump.
At anyrate, there is a solenoid that cost $10 that could be the problem. You need to test the solenoid to determine this.

My car had this error code also. The hose that runs underneath the intake manifold had a crack in it right where it makes the tight bend and connects to the control valve. I cut about 1/4 inch off of the old hose and reattached it to the control valve and I have not had the error code since...... knock on wood.

yep that's it. It's P0 code 410 or 411 right? Mine was solved by replacing that same exact line. it's a PITA, but will fix the problem. Do yourself a favor and replace it with high temp silicone tubing instead of regular rubber.
Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (GLX96)
thanks for all the suggestions. i have to check the hoses. It's annoying seeing that yellow light all the time. Where is the solenoid? The thermostat was replaced a month ago by dealer ( what a rip off close too 400 ) Thats another story. Still having the same problem with new thermostat.
Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (GLX96)
My yellow light sstays on now.. (cause one of my hoses are shot...) I covered it up with a Koni suspension emblem! hehe!! No more CEL light!
I can still see a small glow of it at night!
Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (passat_guy21)
Can anyone take a picture of the hose that causes this problem and post it? I replaced a hose from the airbox to the intake manifold today that had a cut in it, but I'm not seeing any other damaged hoses.
There is a green plastic tubing that goes along the firewall to someplace on the drivers fender, can anyone tell me what this is for? I couldn't see a decent picture of it in the Bentley.
Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (vwboomer2)
I'll try to take a picture tomorrow and mail it to you since I don't know how to post pictures on here.
You don't have to remove the intake manifold.. but it does take some jiggling and figgling of the big airpump thingy to get in there.
Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (FowVay)
you can host your picture here!
save the picture on your computer than go to that page...
select browse... find the picture... then click open
then click upload....
Next you can highlight the IMG tag hit the copy button and paste it directly in the areas here where you type your text!!

Sorry, I posted the image from the Bentley's manual but it wouldn't publish here for some reason. It is a excellent diagram of the placement of the components. If you want to browse here you can look at it: http://www.pifiu.com/vortex/up...y.jpg
Otherwise, here's a picture of the front of the engine. Look at the grey hose directly under the intake manifold (mines grey, yours will be black). It attaches to the little black valve called the secondary air injection solenoid. You have to remove three bolts that hold the big black motor (secondary air injection pump motor) in place and you have to unfasten the air hoses that connect to the motor in two places. You'll see them once you start the project. Once the motor is removed you can get your hand under the manifold and unhook the hose from the combination valve.
I have many more pictures but they're not really of much use except to see my beautifullllll VR6 engine
Thank you very much for the tip on posting pictures here. I just got a digital camera for Christmas and now I can bore everyone to death.... haha

Great pictures. I had the same problem and it was a cinch to fix. Cost me just a few bucks to replace the vacuum hose. The only glitch I had was that I removed the wrong hex bolts. My bad. The bolts I should have unscrewd should have been the 6mm, and not the 5mm. Once I got the 6mm off, I could access the vacuum hose at the combination valve. It was a tight squeeze without removing the manifold but I was able to feel for it . Total time spend was around an hour with the goof I made. So, I think if I were to do it again, it would have probably taken me no more than half an hour. Thanks again!
Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (passat_guy21)
Did any of you hear a sound like a vacuum cleaner coming from the engine associated with this code? My car is throwing the same exact code but with a sound like a jet engine or a vacuum cleaner.
The vacuum cleaner sound is normal, it's the air pump coming on. it pumps air from your air box into your head on cold starts to help the fuel burn more completely/cleanly.
Normally your cat. cleans your exhaust, but it needs to be warm to operate properly. This system only runs during cold starts if the collant temp. is below a certain level. OBD-II runs diagnostics on this system periodically, and if an "incorrect flow" is detected, it will trip the light.
went to the dealer and had then do a once over for my car... they told me sumthing about DTC for 2nd air pump$524 fuse blown $.50 the guy told me it was for emmisions do i really need it?
Re: Secondary Air Injection Pump - Incorrect flow detected - Anybody have this DT ... (FowVay)
In case you were wondering, I have some oil on the top silver plastic over of the VR6 like on yours jsut below the oil cap (mine was in the exact same spot). Mine was caused by oil seeping from the heatpad/soundproofing mat on the underside of the hood. The pervious owner had left the oil cap off once and the oil got in the mat.
Using plenty of simple green and the the pressure sprayer at the car wash (not too close! it will tear it apart if too much forceful spray is applied) the oil "leak" went away.
Nice clean engine bay.

i just got the code, i am not fu*king with it, dealer wants 524 for just the part, its NOT a neccessary thing, and who in the world doesnt know someone who knows someone who can hook em up with a inspection sticker
I recently had the same problem. Stealership wanted $700 to fix the Sec. Air Pump. What BS. My CEL came on again yesterday. Went to Autozone and yes it was 0411. They cleared it and it's cool now. I need to replace all the hoses and that will definitelt help.
