My battery is dead -no surprise, already bought the Duralast replacement. When I was poking around under the hood (front) I heard this faint whirring noise while the car was turned off. It came from the driver side. I went back hours later and still it was audible. I seem to remember from my VW years something similar. Is that normal? Or is that why the battery dies? I will have the car looked over before I start driving it full time.

Do you hear noises too?

Thanks.

It is hard to believe I own a 911 :jump: :rolleyes:

You need an amp meter to measure the load with the car ignition OFF and key removed.

It should be 40 - 60 ma. If it is more then that then you have a drain.
