  1. Volkswagen Passat B5 Discussion
    This is just thanks to all in this forum. I acquired this Passat wagon that was oozing oil, had a nasty knock and had no boost and due to the input and motivation provided here, I now have a Passat that is clean and reliable. I feel that the contributors to this result need praise, however...

    I followed all the steps in this post. http://www.passatworld.com/forums/volkswagen-passat-b5-discussion/333196-how-b5-manual-air-conditioner-troubleshooting.html - Temperature Flap Servo works - A/C Clutch Relay does not have cracked solder as far as I can tell. Also, when I turn on A/C...

    My 2002 V6 ATQ (191K 29MPG Highway 23 City) was due for state inspection so I needed to come up with a fix for my P0421 P0431 CEL codes. I planned to replace both rear O2 sensors, but first wanted to be sure this wasn't due to poor combustion performance or an exhaust leak. So I put 1 bottle...

    This is a new problem (at least to me). My kid's 01 B5 GLX 4motion wagon makes a squeaking noise when the brakes get warmed up. Driving short distances on relatively flat ground I never hear it. But if I take the car into town (3000' drop in elevation over 10 miles), by the bottom of the...

    My 2004 TDI air conditioning blows good cold air while driving, but in traffic or sitting at a light the airflow cycles between warm and cool. I check the freon charge and it is fine. At idle in my garage the compressor cycles on and off. Clark

    This is a shout out to the posts/threads regarding Air conditioning blowing warm air. Well after recently changing out my timing belt, tensioner, water pump, coolant, ect... I got my baby all back together, which I found actually a little easier than I've found on other vehicles short of...

    my 2000 passat B5 takes 20 to 30 min to warm up under load and doesn't warm up when idling (tried turning on the car in the morning and the engine showed still cold after 30min). Would anyone know how long should a 2.8 v6 take to warm up to a normal temp, or is it normal for it to take a long...

    After my timing belt job was done, my car will not warm up to 190. It gets very close, then it stops and stays there like normal, just half a mark below 190. I replaced my cts and my thermostat today with the same result. Its probably not that big of a deal but it bothers me for some reason...

    Here is a video of what I'm experiencing during a cold start. Rough Idle, Misfire codes, as soon as the SAI system turns off everything evens out as you will see at the end of the video, also notice the weird sucking noise.

    As the title states, I have a 1999 V6 Manual Passat and am having an issue with starting. 1. Cold starting is perfect. 2. Hot starting is perfect. (After car to temp, can shut off and then restart with no problems) 3. When unable to start, no smell of gas during cranking or after start...

    Hi guys, I got a check engine light with P0421 again. For once I didn't get it for my secondary air system. However, I got an evap code (large leak) guess what? The wawa I got gas at didn't freaking put my gas cap back on and I lost it when she said we throw them out just get a new on at walmart...

    Good afternoon guys & gals. I own a 2004 vw passat 1.8t with a 149,537 miles on it. I have had a whole host of problems with my car but have been able to get most of them corrected. My current problem is with my heat. Prior to winter my temperature gauge would go directly in the middle where it...

    Need help to stop eng. noise. 2007 Passat 2.0 T, 72000 miles. I was suspecting that the idler belt tensioner was the culprit, I was wrong. I was going to replace it but I didn't find anything wrong after it was removed and inspected ; no wobbling, the serpentine belt OK. I started the car for a...

    help a Passat Newbie! I've searched and can't find the answer to my particular issue. I suspect it's more than one: FWIW it's a high mileage 284k km Drive by Wire 5.5 tiptronic wagon. From cold start the idle often surges from about 800-2k for about the first 15 secs. Then it lowers to about a...

    2005 Passat 4 Motion 1.8T. 122,000 miles. A/C worked fine last year. This year not so much. Wife said it was working but would take some time to cool down, say an hour of driving and then 20 min the next day and it was cold. Checked the R134a and it needed a pick me up and blew cold until...

    2001.5 1.8T sounds like a diesel when warm & is very noisy upon strat-up. What wrong? I've actually had people ask me if it was a diesel. It has 101k on it. Had the sludge issue at around 70k, which, the VW dealership fixed. Been running synthetic in it since...as well as letting it idle for a...

    I'm not sure if the search function is working. It did not turn any topics up. My daughter's 2002 Passat 1.8t automatic has the AC start blowing warm air usually at a stand still. It then seems to kick back on when running. Any suggestions? It is hot in Florida and is much needed. Thanks

    Hello everyone, first of all I have to excuse me for my bad english but it's because I'm from Germany. Anyway, I have a VW Passat (1998) 1,8l ADR with a V20 Engine. The problem: When the Engine is warm (~90 °C), you can hear loud untypical sounds while stepping on the gas. Doesn't matter in...
