So what happened to my car?

Today, my 7 year old E90 battery was totally dead. Yesterday, it was fine. So I hooked up my battery charger to the positive post under the hood and also to a bare nut (for a ground) at the top of the strut tower. Red went to positive and black went to the ground.

So after a few seconds of the charger being connected, the car started blinking inside and acting like it wasn't hooked up correctly. I immediately unhooked it and was perplexed as to why it wasn't charging correctly. Also, I can't seem to get into the trunk with the key inside the remote.

What could be going on here?

Any help is appreciated.

Well for one your batt is probably just that dead.

2 you are not grounding it properly. There is a ground lug on the passenger side of the engine. Ground it to that. The bolt @ the strut is not a good ground.

Thanks Juiced.

So why can I not get into the trunk? I am using the manual key inside the remote. Do you have to have power to open the trunk?

Yes, power needed.

Be careful - you can lock yourself in the car when the battery goes.

Good idea. I tried that but the car still flickers like I'm trying to kill it electrically. I'm really surprised I can't get it to charge.

If nothing else works, I'm going to have to have it towed out of my garage and to a shop.

Any other ideas?

Do you have the valet switch, switched to off? This will prevent you from getting into the trunk.

How long are you leaving the charger on before trying to start it?

Isn't there an emergency trunk lever somewhere in the car in case your keys are locked in the trunk? I thought I read that in the manual, but maybe I have it backwards?

Yes, there's an emergency release in the trunk.

But, I didn't write trunk. I wrote car, which you can be locked in if battery dies while you're in it. There's no release inside car.

I can see the unlock button not working, but pulling the door handle twice won't work? I always assumed that was a manual thing.

Nope. The double pull requires electricity.

I was glad too until I realized it won't turn if the battery is dead. In other words, I could not get the trunk open with the key.

I had to try the inside release button once I had the battery charger hooked up to it to get it to unlatch. Shortly afterwards, the car went completely dead even with the charger connected. I'm in the process of replacing the battery now.
