  1. Volkswagen Passat B5 Discussion
    Hey all, please let me know if there's a better place to post this. I'm a mechanically inclined tinkerer and paying to have things fixed wouldn't make financial sense given the value of my car. I've searched these forums and read so much, but can't quite find the information I need. ETKA...

    I managed to get a P0411 code that had an obvious cause after inspecting my vacuum hoses. (Hopefully it won't have a secondary cause, but it was ok until I was messing around with a speedwrench to remove the top flange nut. Apparently trashed the little vacuum elbow on the combi valves.) So I...

    This just started popping up. Looked up the code and seems to be the secondary air pump, either the pump itself or the lines. I located the pump, just seems really tight to get to it and the lines with the bumper on. Is their a way yo get some room to pull the bump if needed or am I pulling the...

    I have had an intermittent P0411 code for a while, and want to get the car ready for emissions testing in a couple months. Initially, I had replaced the vacuum 3 or 4 vacuum hoses, all the way from the diverter valve to the kombi valve. This did not fix the intermittent P0411. Note: the pump...

    2000 ATW. I got the P0411. I read a million threads but haven't seen much discussion about carbon blockage in the passageways beyond the combi valve. History is I had many problems with the SAIP over many months. I had both hoses cracked - replaced 'em. Had an intermittent clicking and...

    Hi All I looked at a 2000 Passat with the 1.8 liter engine. It has almost 200,000 miles and when I had the codes red it gave me the code p0303 and P0411. In Reading a thread on this forum I saw the P0411 code with an engine misfire on cylinder number 4. That thread indicated the cylinder...

    My last issue was the turbo and a P0420, but that was solved by changing the cat... and with much help from Steve in Chicago. Even with the turbo/cat problem fixed I am getting all the codes above and my performance is suffering. Back when I was having turbo issues, I performed a boost leak...

    So I've got to get my emissions done which means getting rid of my CEL. I plugged my OBD in and only got P0411. Saw it was related to secondary air pump. I unplugged my SAIP awhile ago because it was making a horrible whirling sound and I read on here it isn't necessary. I thought this was good...

    I have a 2004 vw passat 1.8t 4 motion awm engine code. I need help passing a state emissions test. History on the car I bought it a year ago have had no issues but a misfire due to bad plugs in January I slid into a curb causing a small crack in the intercooler small enough that I was still able...

    On a 1999 V6, I am getting P0322, P0411, P1338 codes. Check engine light has been on for about a week now, so I don't think it will go away by itself. The car starts fine. I check the codes via the link below. What do I do now? Should I just delete the codes and hope that they won't come...

    I have recently nursed a 2001 GLS wagon 1.8T AUG (with AWM head) back to life. In about 200 miles of mixed highway and city miles, I have gotten the "Emissions Workshop" alarm on a couple of random occasions. The code I pulled was the 16795, reverse flow detected SAIP. I have followed through...

    My SAIP is dead, even after installing a new one last year. Since I'm overdue on my inspection, I cannot pass. I can clear the code, but I do not know how to set the readiness codes. Is there a way to reset readiness without replacing the SAIP?

    So my 03 passat was throwing the lovely code for about the past 2 years now. The code appeared sometime after I purchased it from a dealership. Anyways, since we were selling the car, we changed the stupid headlights from HID to stock (the PO had made the mod and the lights were shoddy...

    I didn't see other questions like this....How many times after engine startup does the air injection pump get activated? Mine activates when starting the vehicle and no cel. But after a few miles of driving...somewhere around 7 miles (10 minutes) the air injection pump turns on again and that's...
