    Just out of curiosity, why is this pump necessary? It's on my V6. I had to cut the electrical line to it during my TB job because I couldn't get that damn proprietary connector off (couldn't see it well). Going to solder it back up today. Now that I've seen the same type of connector, from...

    I've been wishing I had an aux in to allow streaming form my phone. Today I looked through the manual for the standard install RCD 300 in my 08 estate. It referenced switching between the installed cd drive and a multi media socket connected to an aux-in!! It referenced the 3.1 manual. the 3.1...

    I stupidly did not disconnect my battery before doing some work on the wiring to one of my rear auxiliary power outlets. Of course, since it is always hot, I shorted it out, and blew a fuse. You'd think the location of this fuse would be shown in the owner's manual or the service manual I...

    Hello all. I bought a 2003 Passat 2.8L V6 for my wife a month ago. I have been going through it fixing all the little issues. I fixed the oil leak which came from the passenger side rear cam plug. I bought a new one online and lubed it up with some Gold RTV and let it sit for 24hrs. The oil leak...

    Hi all, My a/c compressor kept on turning on and off when I kept my car on idle while turning on the a/c. So, it only blow cold air for a moment and then hot again. But after I drove it, the a/c kept on being cold. I also noticed if kept on idle for a while, the temp starting to go above half...

    I have decided to take the HU out and replace the CD changer input with a 3.5 mm input. I have found two types of converters. Ones with an input on one end and a 3.5 mm on the other and ones that had a small box in between. The first one is alot cheaper, what is the difference between the two...

    This one's been bugging me on & off for a couple of years, but it started up again and I still can't figure it out. You know the sound on a hot summer day where the secondary radiator fan kicks on for some extra cooling power? I get that even when it's 40 degrees outside and the engine is below...

    I bought a AFC Unit like this one Amazon.com: Stribel Auxiliary Fan Control Unit: Automotive from the scrap yard. Was having a battery drain issue. Salvaged AFC fixed the drain. However, when I turned on the A/C the Aux Fan did not start up. It spins fairly freely, not like a pin wheel, but I...

    I recently bought a 2006 b6 2.0T without any auxiliary plugs for mp3 players or ipods. I was thinking about replacing the whole stereo, but then I found a mystery 12 pin connector hanging from the CD compartment in the glovebox. Does anybody know what this is? Is it possible to convert this...
