    hey y'all, i just picked up a 2001.5 passat 1.8 5 speed that developed a misfire while driving home immediately after buying it, I changed all 4 plugs and coils and the misfire went away. I reset the CEL by disconnecting the battery and drove for about a week before it came back on with the...

    My youngest went up to the cottage last Wednesday, he took the Passat, said he made the trip in record time and all was well. Thursday evening he calls to tell me the CEL is lit and the engine is rough running. I assume that it probably needs new ignition coils, because all Passats with 1.8T...

    I apologize in advance, this is a dumb question. I replaced my front drivers side upper control arms. I replaced them because I had a knocking sound coming from the front end. That was a few weeks ago and the knocking sound stopped. I meant to check the passenger side but I forgot. Now I...

    Hi guys! I have a 2003 Passat Wagon GLX V6 Automatic (Tiptronic). It appears to have a slow transmission fluid leak on the passenger side, just in front of the transmission pan. From what I've read, this may be coming from a bad seal in the differential, which has gear oil in it? I am almost...

    My 98 passat has developed an intermittent problem, where sometimes is not regulating the rpm good and I have to pump the gas a few times so it gets reving and then I can engage the gear. I connected my vagcom and got the errors you can see in the screenshot. Where should I start looking for the...

    This is a 2007 Passt 2.0T (FSI). Last week the car failed to start and there was no sound of the LPFP (in-tank transfer pump) priming. I didn't have time to mess with it, so I towed it to a local shop and they confirmed that the LPFP was shot, and replaced it. The car ran fine for a day after...

    Vehicle: 2010 Passat Komfort, I assume 2.0L. Engine cover says TSI, which I don't know what that means. 54k miles, last service by dealer was at 40k miles. I changed the oil and filter myself at 52k miles (a couple months ago). Driving home after a 30-mile trip today my beloved 2010 Passat died...

Possibilities: Searches have come up with a wide range of answers like brake booster leak, SAIP, A/C fan relay. Car: 2002 B5.5 AWM Automatic 128K. There is no CEL or performance issue that I...

    Sorry guys. When pressing my a/c button, I get nothing. The lines are pressurized (no gauge). And I took out relay 384, cleaned it with a soft wire brush and all of the contacts i could safely re-solder, I did. There was no visual indication the relay was bad besides a little amber corrosion...

    Having very recently bought my 2006 Passat 2.0T, I had to get it safetied in Ontario (where I am registered) by a non-VW mechanic. I generally don't like other people working on my car, but I needed the safety for registration, so I bit my teeth and let the mechanics poke around my new baby...

    secondary air pump system. is it the pump, how about the kombi-valves, did I blow a fuse, can I even get to the fuse - why no, I don't have the proper center pull to remove the windshield arm and if I could remove it none of my meager tools are able to fit through the small hole for the 10mm...
