Ok this past week and a half the car seems to not want to start... it will turn over but from what I can hear it sounds like the battery is getting weak. The dash lights go dim a little when its cranking and it just sounds like it doesnt want to start.

Today was the worse... it was really hard for it to turn over but it did and once started the iDrive told me Active Steering Malfunction. So I shut it down and restarted it... the message went away.

The car gets driven enough to get a good charge. It gets driven about 300 miles a week.

What do you guys think? The battery just going bad or is something drawing power? I've checked... and I have nothing plugged into any of the power sockets...

Just wondering if anyone else had problems similar and how it was resolved. I scheduled an appointment with the dealer to have them take a look at it day after Christmas...

Although most batteries are advertised with a 5 year life, they often don't hold a charge that long depending on usage. I usually have to replace the battery on my Camaro every 3 years due to the stereo system I have installed,

Since the E60 has so many alectronic components in it, its certainly possible for the battery to be weak. But brining it in for a test (alternator, etc.) anyway can't hurt.

I just changed the battery on my 04 545i. Warranty may have covered it, but it was Sunday and I had meetings lined up on Monday AM, so I had no choice but got a comparable replacement.

The lifetime on my previous e39 was about the same ... had to replace it after about 3-4 years. The good thing is that the new battery isn't as wide, providing me with additional storage space in the battery compartment

Had the similar problem. My car would die everywhere until I placed the battery. Now no more problems. Let me give you a piece of advice-depending on your relationship with your dealer, it's going to be about $350-$400 for the battery and installation. I would buy the battery yourself and pop it in. It'll save you a couple of hundred bucks. That's what I did.

Thanks guys. I was hoping it was only going to be the battery.

I'll see if I can get the dealer to replace it under warranty.

Please let me know how that goes... I believe my dealer may owe me one, since I replaced it myself.
