Thanks I'll have to try those instructions. Called the dealer yesterday and they said "90% of the time it's a loose gas cap, and it takes up to 10 days for it to clear once fixed. Call back if it's still on after 10 days." That sounded a bit odd to me. What if it's NOT a loose gas cap???
Anyway, a stupid question regarding the diagnostic mode II instructions: Is it possible to flood the engine or otherwise do bad things by pumping the gas pedal like that, or are we safe because it's drive by wire throttle? And, what precautions (if any) do you need to take before trying this? Someone mentioned something about making sure the battery is fully charged (?)
I'll revive that thread if no one has the answers here.
