Hey kat, search option is offline atm due to the probs it was causing. Re-setting the ECU can be done by disconnecting the battery! It needs to be off for half an hour, then re-connect it and turn the ignition on to the first click, just so the lights are on. (do not start) Then leave a further half hour. This will re-calibrate the ECU. If you didnt do the igniton part kat, this may be why it didn't work! Afaik, sharans are OBD2, so it wouldn't work on your car : (
