    Hey everyone, I recently bought a 2002 Passat GLX 4motion with 140k km/85k miles on it knowing its secondary air pump was on its way out (old owner described it as doing the characteristic deafening vacuum sound last winter). I've had the car for about a month and just got around to buying...

    I have seen some older posts addressing this topic but bringing it up so we have some pics for the next generation of PWers. So I got the codes above and knew it wasn’t the SAIP pump itself since I could hear it. Next up, check on the combi valves. I didn’t need to go far - as soon as I...

    Hey guys, So the 02 Passat 4 motion I picked up came with the CEL on and these codes. Try as I could to hear the SAI pump running on cold start, I could not. Even when turning off the motor, giving it a chance to begin blowing after starting, I would not hear the vacuum sound winding down. I...

    Hello everyone, this is my first big post (Yaaaay, I have a problem!). 2002 2.8L V6 GLX 4Motion Wagon, 189000 km. Have recently (within three months) replaced the alternator, timing belt and tensioner pulley, spark plugs, plug wires, and ignition coil, and PCV valve. Also had the valve...

    I have a P0491 code that I can't diagnose (Secondary Air Injection System, Insufficient Flow - Bank 1). Here's what I've checked: - Verified that pump is working by unhooking hose at the top-front of engine and feeling strong airflow (and high-pitched wine) - Verified Solenoid using vacuum...

    Hi guys, Just had Autozone look at my CEL and it throws up P0491. Something is up with the SAIS. Super lame. I just replaced my air filter, but I'm pretty sure all the hoses are in tact with no cracks. Because it is just bank 1 I'm guessing it's not a major component in the system, but...

    On my way home today and got a CEL.. checked it out and it read P0491 and P0492 which came to be faulty air injection system flow... Is there something I should immediately check or could it lie within one of my vacuum hoses?? The car isn't running rough at all, which is why it surprised me to...

    Hello. I'm a noob, so i might not know the right terminology but, i am having a bit of a problem with my 2002 V6 Passat. I have tried search, but it seems everyone is getting different answers. It all starts with the Check Engine Light coming on, Error Code P0491 and P0492. Since i work at...

    I posted the CEL P0491 and P0492 (Secondary Air System Banks 1 and 2), I read some of the older posts, which say it could be hoses to the SAIP (Secondary Air Injection Pump) or the pump it self. I checked the hoses to the pump and they appear to be okay. How can you test or check if the pump...

    This is what the Actron OBD2 is giving me... I can't find that code in the link I was given here... I have read here about a pump, a valve, a hose, but no real answers it would seem. :( Has anyone else had this code? What's the fix? I don't want to just start replacing things for no reason...
