jumping and recharging the battery is not the same as reconditioning the battery - a jumped and recharged battery still can malfunction, due to inherrent nature of the chemical structure of the battery. i don't think you want to hear a lecture on chemestry, but we still did not rule the battery out of the problem...


the turn signal light is desighed to stay for at least 10 hours without killing a good battery - it will of course, kill a bad battery or even a good one in couple of days... that is a standard euro feature, and given the fact that parts are super expensive in europe, many euro cars will have these lights on without draining the batteries...


can you take the battery to a place that can do a load test and a deep charge of the battery? a car parts store should be able to load test the battery...
