musings of a crackpot hacker

Updated my car maintenance kit

Posted By on December 7, 2013

Some years ago, I bought a USB OBD-II adapter, set up an old laptop with XP and some software, and used it to figure out what was wrong with cars.

Well, that setup doesn’t work on the Tiguan (works for the Jetta, but not Tiggy), so I bought a newer OBD-II reader. This one is Bluetooth and seems to work well (it can talk to all three cars, at least):

The bluetooth setup works with Android devices (iDevices require rooting, apparently, so you need to get the WiFi version or something.. I don’t know, I decided to not care and got the Bluetooth one).

So, you take that, and your tablet, and then install an app that talks to it (there are a pile, I found these which seem to work well:

Carista just sets and clears codes. Torque does that and shows vehicle information (throttle position, RPMs, speed, etc. – pretty much whatever it can get from the ECU).

I ended up buying Torque Pro which adds a pile of nifty features. Most useful for me are:

  • Profiles for different cars
  • Support for diesel engines
  • Support for turbocharged engines
