This Obd2 dongle works with my wife's 2010 TD forester and not only does it clear codes when calibrated to the vehicle (very easy) it has the engine parameters as well
boring video for torque pro
Have these (ELM & Torque Pro) and use them on other makes BUT they will not read the 'Bug'. After researching Code reading on Subie Sites, I have ordered an OBD2 VAG COM 409.1 Diagnostic Cable. Free SSM is installed awaiting the cable. This is purported to be the correct configuration for reading a GG.
IAT arrives next week. Hopefully this will be the fix.
