Well, I've got a cycling Failsafe Engine Mode with no engine light or limp mode, so I need a code reader. I'm looking at ELM327s, but they come in so many flavors (mini-bluetooth, full size bluetooth, usb, etc). Any suggestions as to which one is best for our S-Types?

I combed through the OBDII threads, but I'd like a shout of confidence from some S-Type owners.

 

go to scantool.net and check out the cheapest red unit.

it comes with usable software whereas most of the $25'ish units do not.

 

I bought one of the larger blue tooth scanners. Works great with my android app Torque.
