One problem related to alternator/generator/regulator has been reported for the 2002 BMW 330. The most recently reported issues are listed below.
The battery of the car drains out every morning and I need to jump start my car everyday in the morning. I have got the battery, alternator and the charging circuit checked and there are no faults with those. The battery is only an year old. I suspect that something is running in the background after engine stop or there may have been a short circuit which is draining out the battery.
