Parasitic Battery Drain e53

[g300d]

Thank you gents for clarifying the AC thing.

One thing though, I noticed that if I shut off the car and turn it on again, AC does NOT come on?

Anyway, I didnt feel like unloading the back and hooking up a DMM to the battery just yet. I did remove every fuse related to the radio and telephone system in the trunk first, and checking voltage on the OBC.

At shutoff I usually have 12.4-12.6v. After 2 days I was at 12.1

Still not good enough I think, really need to find the time to hook up the DMM.

12.1 after two days seems within spec.

It is? I hope so!

I used the X today and when I got home it was at 12.6. Will let it sit longer and check voltage again. Dont have time yet to do a proper check with a DMM.

Something else popped up though, lost the turn signal indicator and audible clicking when I use my turn signals/hazard lights. Quick search says cluster. Argh.

More like I-/K-bus problem.

It's a BMW, which makes them optional.....

Although I do agree it sounds like your K-bus signal is getting interrupted

Would appreciate some direction on I/ K-Bus, no experiemce with it.

EODguy, that is what pisses me off, signal light is barely used and still craps out.

I don't know Andrew. My X5 has been sitting since Wednesday and it's showing 12.7 volts.
Dropping to 12.1 in just 2 days, I think there's a drain for sure...

"use it or lose it".

Kidding aside wiring gremlins are an age issue as much as a wear issue
