This question probably doesn't matter, but WHY was the battery replaced?
Would you say this problem started immediately after the battery replacement, or a few days after? If it happened immediately after battery replacement, than it's likely related to it. if it took a few days for this to happen, then probably not a factor.
I'm curious if you have a "check engine" light yet, it may take a short time for the light to activate. I'm assuming (possibly incorrectly) that the engine control system (diagnostic module especially) are identical to a US version car.
