Drawing Power - Sleep Mode?
My car has been having long crank issues and they have been getting worse. Now keep in mind i have 215,000kms on my original battery on my 2011 335i. I realize that I am probably long for a new battery and will be having one installed next week.
My question is as follows.... The dealership tech is concerned that my "upgraded" audio components may be drawing power when the car is either in Sleep Mode or trying to get to sleep mode once it is turned off. I do notice that my JL Audio 900 Amp does stay on for about 10 seconds after the car is turned off. Is there anything I should be looking at that may cause with the Amp, Sub, or door speakers to continue drawing power? Thanks,

Lots of people have these few have problems.
Lots of people have the Jl 600/6 few have problems.
If you have the Technic harness the turn off signal goes off with sleep mode. About 6 years is the average life on the battery but if you driving a lot it might even go further. Actually I haven't heard of anybody having a problem with just single JL 600/6 Vp told me I could have three of them if I wanted and it still wouldn't be a problem. The only way to have a really find out is to measure it. The whole car draws power when its not in sleep mode about .5 amps . And I assume its started to get cold in Toronto. which aggravates battery problems. Last edited by ctuna; 11-12-2015 at 09:26 PM.. |

Well the dealership tech should hook up a simple draw test, but going to be in your dime due to the extra equipment.
Is it a slow/weak long crank or a fast long crank. One could be fuel one is a weak battery. |
