communication

So my dear friends at Passat World, I have come to my wits end trying to figure out what exactly is going on with my W8 Passat. I pulled the door apart a few weeks ago for 2 reasons, the locking mechanism wouldn't function 100%, and my window regulator was shot. Upon replacing both (with...

Hi all, I bought my niece's car recently (02 Passat 1.8) and flew to western Canada to fix some minor things (alternator, TB cleaning and vacuum lines). Once I'm done, I drive it back to NYC. I did a scan with my Vag-com before I changed the alternator and cleaned the TB. I came up with a few...

I have a 2002 v6 passat and CEL just came on and try to read it and no luck, it powers the OBD 2 reader but no communication to on board computer.

Hi guys I have been having this weird issue with my car since I purchased it and kinda afraid the PO didn't know what they was doing in terms of repairs. I can read all of my car's modules in my car EXECPT my engine, I have no power to the K-line what so ever, I replaced the ECU to see if I...

Hi Guys, I've had intermittent ABS issues for awhile now and seeing as how it's winter thought I should actually do something about it. I scanned it recently and this is what it found: Address 01: Engine Labels: Redir Fail! Controller: 4B0 906 018 CM Component: 1.8L R4/5VT G...

Hi guys I've been an avid reader since purchasing our first VW a 1999 v6 Passat auto a couple of months ago. I've fitted a 2003 trans to it and have now realised that the late trans runs can bus and the speed sensors are incompatible. It looks like I will need to fabricate a small bracket to...

My Passat recently developed a strange issue. I noticed that a few weeks ago I lost interior lights, keyfob functionality, etc. after I used the passanger door. After a little bit of time I noticed that it began working again. It continued to work until a week later when I used the passanger...

Just bought a 1998 passat 1.8 l and I have no commutation with the data line I have performed all the check. But I have not taken out the dash to check the airbag module .I has check all the other module. Will a door module cause this to happen? The problem I am having is that I have 10.46 volts...

My brakes have been weak for over a year (I don't drive the car much right now). I have replaced all front and rear pads and rotors, and fully bled a couple times. Replaced the master cylinder, though I don't think that was really needed. Pedal feel is poor: when car is off the brake pedal...

Okay, here's the story: 2000 ATW. I was having minor misfires, similar to the last time I had a coilpack starting to go on me. I'd feel it lower down in the rev range but was still very driveable. VAG COM says it's #1. Order a new Beru coilpack and bring it home. The next morning, I go...

could you guys suggest some solution? I failed inspection, because they can't communicate with OBD with their device. They tried few times. Autozone was able to communicate but after third attempt. I get code p0441 that I think it's related to malfunctioned purge valve. Do you guys know how to...

hey guys i have a sittuation, i have put my car on computer to clear up codes, but as soon as i go over 25 mph, it says lost communication. what should i do? thank you

I recently picked up a 2002 1.8t Passat. The car needed the head replaced and got that all done. Went to start it and it won't start. There is no voltage at fuse 29 and 32 (which are for the engine ECU). Looking through the Bentley, there is a relay that controls power to the ecu. I don't...

Any idea what this means? Ever since my battery and alternator died and were since replaced, my CCM keeps my air conditioning on all the time except when I turn off the climatronic. Clearing the codes does nothing as there is a communication error with the CCM only. My mechanic is stumped, he...

Hi! I just came with the idea of buying and installing a B5.5 Armrest center console. I found one (OK everything seems to be fine): BUT! I have a problem: What should I do with my OBDII port? :confused: HELP! :D

Hey, I need to get emmisions testing but my car won't communicate with the ODBII scanner I have and it is a decent one. I also had someone hook up a VAG-COM and no communication. I read somewhere that the JEtta's computer goes out of wack with a aftermarket radio and them the system does not...
