Even if you still had that old interface (and Vag-Com), it would not work with your new car. All new cars (since about 2006) are CAN bus while your old Vag-Com interface was only K-Line. All new Ross-Tech interfaces support CAN bus cars. If you are looking to get a used R-T interface you will need a Micro-CAN or a HEX+CAN cable. Other interfaces are K-Line and only for 2005 and older VWs.

Have Fun!

I might be a little late to the game re OBD scanners. Just ordered a generic WiFi OBD II scanner from Amazon.

I really want it for reading DTC's and maybe a few other things. I don't intend to DYI the fuel filter or do much other DIY work. Just bought my teenage son an old car, so it might come in handy there too.

So tell me, what does the VAG-COM do that the generic $20 OBD II scanner does not do? Seems that the VAG-COM is tailored to the VW/Audi.

Keep in mind: I'm giving my Jetta back to VW next year via the BB and I'm not 100% sure what I'm replacing it with. Second, my son has a non-VW car and I want the scanner for his car probably even more than mine.

No need to buy one if you don't need it.
The VCDS (vag-com) is reverse engineered from the VAG tool. It is the only device (other than the VAG one) that will communicate with all the modules and read all the correct codes. That being said many folks get by with other devices with varying levels of success.

VCDS will access all modules on the car, unlike generic OBD-II, which is emission-centric, and only covers a very small subset of what is on a car. VCDS also allows sending commands to start tests, as well as the ability to code/configure modules and perform adaptations, none of which is supported by an OBD device at all. If all you need is to read generic OBD-II codes, then a cheapie will do the trick. If you actually plan to do any real work, then VCDS would be a far better choice.

Thank you. That sums it up I guess.

I would like to get a reader for my '06 Jetta wagon but I don't have a laptop I could use with the VCDS dongle, plus I live in an apartment so even an extension cable to my PC is out of the question. Is there a way to store the data on a USB stick so I could use it on a PC elsewhere? I looked on the Ross Tech site and couldn't see any info other than their VCDS Mobile which is pricey. Are their any other products available that would work for me, i.e: an OBDII reader, etc. I am not very knowledgeable with auto repair, I am just looking for a way to check what the potential issue is before I bring it to a mechanic. Thanks for any suggestions. :-)

Nope. OBD/VAG is an interactive protocol, not just a passive data dump. It doesn't need much of a computer, so if you can get an old laptop for cheap, it should be enough.

TDI(s): 2006 jetta
Default What VCDS program system do i really need?

ok, so i have read alot of these posts, not all as i wasn't finding what i was looking for after a few pages. i looked on ross's site about the different levels of the vcds programs. a bit confused as to what i will need for what i'll be doing. i look at the prices and then features and they seem about the same to me.
WHAT I'LL BE DOING...2006 jetta tdi with brm engine and auto trans.dsg
I need to run certain tests such as kicking the cooling fans on or checking the solenoid in the ac compressor or resetting an airbag light. could be more if another problem comes up. at the moment i don't know anyone with the scan system and sure as hell not driving an hour and get over charged by the dealer. my ac stopped working a couple weeks ago and think i have it narrowed down to the fan module or the compressor solenoid and or both. got both parts ordered and will be here tuesday. i have used the cheap scaners for years such as from napa or harborfrieght just to read codes on different cars. my jetta goes into limp a couple times in the winter and the codes that came up were the throttle position pedal and something else to that affect. i reset the system and pretty much comes out of it. something seems to get wet to me. ...So those are the things i deal with . what cheap ross sytem will do all this stuff and what windows operating do i have to have. i seen someone mention they were going to use a cheap netbook....an elcheapo netbook is all i need?, thanks in advance, this programming system is going to be way new for me as it can't be compaired to a store bought scan tool.....
