Its for carrying out diagnostic checks of any ECUs in the car, using the OBD port. www.ross-tech.com is the manufacturer and has loads of info.

It's pretty much the same as the system used by the dealer, to check the car out.

Just got my hands on a V-Checker (thanks Fuzion!) - absolutely no idea how to use it yet but if someone wants to help me learn on their car (or mine) then I'm in Glen Iris, Melbourne. Drop me a PM.

I have a knock-off Micro-CAN VAGCOM cable that works with VCDS in shareware mode. I've tested it on my Tiguan and it'll scan for error codes no problem. Should work with any CANBUS based VW.

If you'd like to test it I am in Panania, Sydney.

Hey, I don't know if anyone has seen this before but there is a VAG-COM "How to" document here http://www.golfmkv.com/forums/showthread.php?t=7410

From a quick scan of that thread it appears that most people use the VAG-COM to change vehicle setup options like head lights and electric window operation. But can anyone give examples of when they have used the VAG-COM to diagnose and fix their poor running engine.

I have diagnosed bad coil packs and MAFs with mine. There's so much you can do, providing you can interpret the data you can record. The coil pack may throw up a code. The MAF you can pick by looking at the, g/s output. If it is lower than you expect or more often zero, you have a bad one.

For example if the mixture is going weak at the top end, you have to think about the fuel pump.

OK, so say you have a dud oxygen sensor, will the unit pick this up?
If anyone in Perth has VAG-COM, I'd like to offer a carton of beer if they can demo it to me on my MKIV and show up any errors.
PM me.
