    ELM 327 on 2008 GTI

    Just wondering if any one has any experience on using the ELM 327 scanner with various software on a newer model VW, specifically the GTI or Jetta with the 2.0T engine (2006 or newer).

    I'm about to order one off Ebay, but would rather know for a fact it works before doing so. I'm mainly looking to be able to clear my airbag fault to avoid a trip to the dealership to do it. Also, in general this would be great for monitoring my F/A and boost readings.

    Any experience or advice would be appreciated. Thanks!

    You might like to look into VAGCOM. It's like OBD-II, but better

    Better and much more expensive.

    Edit: Sorry, didn't mean to come off as a jerk. I've already researched the VAG-COM and really think it's nifty. However, for the amount of time I'll actually be using it, I don't think I can justify the cost. Since I need one that does CAN, $250.00 is my minimum cost. I just can't see myself spending that much on something so simple.

    Unfortunatly, unless the CAN codes are documented you won't be able to do much with the ELM327 outside the generic standard OBD2 PID values. You can clear the MIL, but I'm not sure you can clear an airbag fault. I think that is another module entirely and you do need CAN to do that. Check the VW forums to see if those CAN codes are documented perhaps? Sadly when most software developers get hold of the CAN codes they never share it, just try to profit off of it.

    I will see what I can come up with.

    In the mean time, I'll most likely order the ELM327 regardless. Outside of clearing this fault, which isn't worth the $250, I just want to have some form of real time monitor system for my A/F ratio, boost, and other basic functions. I'm sure the ELM can do this. When I need more power, or have more reason to do so, I'll get the VAG-COM.

    A/F (outside the crappy narrow band) and boost arent standardized OBD codes, so the likelyhood that you will be able to do so is slim without prior knowlege of the codes, but you can monitor things like engine RPM, speed, and temperature easily.

    What about the OBD scan tool from OBDPros. Should this work better? If it can in fact pick up some more information, such as boost and A/F by chance?

    The OBDPros tool is excellent (i've been using it for about 18 months), however it doesn't matter what tool you use if you don't know the PID's for the additional sensors you're looking for. Try searching for VW PID's and you might find what you're looking for...
