    I am getting code 001109 - EVAP System P0455 - 001 - Large Leak Detected I meanwhile changed the gas cap seal (since the dash warning light was showing that symbol), but no change. What are likely culprits for the leak? Is the EGR pipe (back of engine) and PCV also part of the 'evap system'...

    If you get a check engine light and large evap leak code like I did on my 09 wagon, check to see if your gas cap wiggles a little or a lot after tightening. If so, you can order the part 1K0-201-557-A from the dealer for way less than the entire cap and swap it out in under a minute. Mine was...

    Getting the following codes on my 03 Passat B5.5 1.8T AWM. I have replaced the DV (diverter valve) and had no change in the codes. I have also looked at all the hoses feeding the turbo and do not see any cracks or anything to lead me to believe that any are bad. I'm not sure what else to check...

    Well the T (19 in the pic) junction broke on the Intake maifold side and threw a CEL light(0300) not to mention dropped idle RPM’s as well as giving it a rough idle. I made a temporary fix but need a replacement anyone know where I can get one or is it something I need to source from a hardware...

    Had a P0441 code on my 2004 Passat V6. Replaced the purge valve and verified the valve was operating correctly. Can hear it “tapping” away. Any ideas aside from looking into replacing the vapor canister?

    Hello, About a month ago I decided to try to fix my Evap system since I knew there was a CEL on for it. This is my story for my 2007 Passat: I checked the codes: P0442, P0455, P0456 Evap small leak detected, Evap gross leak detected. First thing I do is try replacing the gas cap since the...

    I am fairly new to the group. I am Charles and very excited to be a part of such an amazing group. This site is more than informative. I just installed a canister purge valve and accidentally tore the rubber encasement. Does anyone know what that rubber cap is called and if you have information...

    I'm about to start the mammoth job of pulling the dash and swapping the heater core on my 03 V6 Wagon. I found a nearly mint salvaged dash assembly to replace my current dash while I'm at it, which is cracked and ugly. Question I have is ... does it make sense to swap the a/c evaporator at...

    My check engine light came on and my 2014 Passat (1.8T, TSI) is making a "putt putt putt" sound. The code refers to an EVAP system leak. Is anyone familiar with this code and the sound that I'm hearing? Thanks in advance!

    Well, it sure looked straightforward enough in the Bentley manual! I have removed the right-side heat shield that sits above the right-side catalytic converter (three speed nuts hold it in place). Having removed that shield, I find that there is a second layer of heat/sound deadening material...

    Scanned the car with a universal scanner like the one at autozone and got that code P0456. Would I get more codes with Vagcom? Where do I proceed from here...

    2006 BPY engine. Bought it with a broken timing chain and fixed it myself. I didn't order parts until I had it apart, just to make sure I had everything I needed. So... it was a month between tear down and reassembly. I SHOULD have taken a couple pics of the hose routing, but of course, I...

    Hey folks, I've recently developed some issues with my car, and I've found tons of great info on here, but alas I can't quite shake them all! The vehicle is a 2001 B5.5 GLX, 30V V6, 210k on the clock and still running strong (for the most part). So it all started with hard starting after refuel...

    Hi Passat lovers! I bought my 2002 passat a year ago and it's a great car, but since I bought it, it had a check engine light on. I had my OBDII scanner with me when I bought the car and it only showed a misfire on one of the cylinders. I had a leak on a valve cover gaskets and oil dripped on...

    Engine light came on and the error code reads P0456 - EVAP Very Small Emission Leak. What could be the issue? :wrench:
  20. Volkswagen Passat B5 Discussion
    Weirdest thing I have experienced....anyone know anything on this one? Filled up the other day at one of the gas stations that has the "MAY CONTAIN UP TO 10% ETHANOL" signs posted at the pump. About 5 minutes later MIL came on - with code for EVAP SYSTEM - SMALL LEAK error. Checked gas cap...
