I am trying to make a bench test to run VCDS software and test a Passat instrument cluster while it is out of the car. I used the pinout specs below and the cluster powers up just fine but when I try to run the Instruments test I get an error message saying No Response From Controller. Any...

Hello dear forum members, anybody has experience with connecting an AUX audio (3,5 Jack) to RCD300 audio system via the CD Changer Port? (perhaps other connecting solution?) I want to play the music from my phone via the RCD300 unit. I have seen on internet they sell several types of adapters...

My VAG-COM won't connect to my 2001 Passat 1.8T. It was working just fine. I went to connect it up to figure out why I all of a sudden I had an Air Bag light come on and I can't read anything. I have not had any other issues or dash error lights come on until yesterday. I got in the car in...

I'm totally baffled. I've been searching for a week here and vortex. I have two antenna looking ports on my monsoon headunit and two wires in the wiring harness that look like they want to go on the headunit, but don't fit. The are both female connectors?? I assume one is the remote wire for...

I have a 2008 2.0t FSI 6 speed, 116,000 miles. For the past few weeks fan has been coming on much more than usual and after turning engine off an accessory, I believe to be the secondary water pump runs for awhile. Temperature gauge stays within normal. Then finally when took car for 10 mile...

Hi, I have a GLS 2003 and need to connect the lights wiring for the 2,000 lbs trailer hitch, but I do not see the cable trunk from the front and I do not know what will be the best way to connect it. I have done this in the past with almost all the cars I had, but looking for info or...

I am almost done the timing belt replacement. Before I put on the front bumper cover I found an electrical wire with a connector is dangling right underneath the passenger side headlight, and near the AC (freon conntainer?). The connector is black like a cube (about 1 cube inch), 4 or 6 holes...

Ok, turned ignition on, display on dashboard was made up of odd lines instead of coherent symbols (mileage clock etc.). The only light that came on was the traction control. Fuel and temp display not working either. Turned car over, it stops after a couple of seconds (immobilizer issue?)...

I've been chasing a small coolant leak for a couple months. It will leak down from the max line to the min line after 3 or 4 days. I can see it on the the belly pan, but it's hard to tell where it's coming from. After taking some pictures around the coolant flange area and the connections...

Earlier this year, I was ripped off by a shop that charged me $140 to "reconnect my radio" correctly in order for them to connect to my ECU. They apparently fixed it and were able to connect to it. Just yesterday I received a vagcom 405 scan tool in the mail and I hooked it up. No matter what I...

So, I end requiring two new parts for my coolant flange installation (2003 Passat 1.8T AWM): --10 mm screw the connects upper coolant hose to flange. There are two that are required. They are quite short. --What I think is a double stud (10 mm); connect the flange to block. Two are...

Hi folks!! i am having trouble connecting VCDS to a 2002 Passat wagon. There is strange behavior. Usually when I plug in and the key is off...the light on the cable end stays red. I have an official ross-tech can-USB cable. On this wagon, it stays red for a few seconds and then goes green...

2000 1.8t 5 speed Okay I'm not sure exactly why but after I swapped to an AWM ecu I can no longer connect to the ecu. I've tried with the motoza software, VAGcom and a generic obd2 reader. I had no issues before the ecu conversion so I'm guessing the problem lies somewhere in there but I'm not...

OK so I have read quite a few threads about OBD II and re-setting the air bag light and I've tried a few things but I cant get it to read the car's computer its a 1997 B5 passat from the first month of production - batch no.3 I believe and this is the first time since it left the factory in...

Greetings! (First of all, Sorry for the Thread Title... I meant to post a question before I read the instructions through...:rolleyes:) Good morning, everyone! I just got my new 2013 Passat SE yesterday, and got to know this site by googling today. May be, I'll be the one reading through all...

What is the best way to install an adaptor in a 03 passat with double din monsoon sound system to enable connection of an mp3 player. I am obviously hoping not to have to use fm transmitter or cassette adaptor.
