5 series battery drain
Hi everyone, I'm a new member with a 2006 525i that I've had for 2 years. I'm having the same battery draining problem as some of you. It all started a week ago. Car wouldn't start so I jump started and drove 20 minutes to work, shut off engine and tried to restart. Nothing happened. Not even enough power to shut the doors. I figured the battery, which is a little under 2 years old might be defective, so I replaced it (at local mechanic shop ) and everything was fine for 3 days. I didn't use it yesterday nor today. I tried to unlock doors this evening but not enough power, so obviously it won't start.
I've never had any battery issues prior to this so this is all very strange.
Any assistance would be greatly appreciated.
