HI

Technical manager just call me now he said while the car is still awake , the power consumtion is 0.10amp and when the green light on the driver door switch goes off is consuming about 11amp , thus he told me may be this door switch is giving me the high battery drain , has anyone have this issue with door switch before ?

 

Any one?

 

I recall someone replying to one of your earlier threads but his issues was the trunk latch. The door switch sounds like a plausable explanation...

 

what do you mean?

 

I have not had the issue with the door swithc on my BMW but this is very possible, and should be easy to check by just disconnecting the switch and seeing what impact is has on the drain level.

 

Well, what are you asking? The technical manager told you they had traced the battery drain issue to a faulty door switch which was, I assume not letting the car go to sleep and was therefore draining the battery. You asked "has anyone have this issue with door switch before ?", to which I simply stated that a previous posted had a similar issue with the truck latch. Sounds very similar to me but trunk instead of driver's side door. Because of this other poster's issue, the manager's explanation for your issue sounds plausable to me.

 

thanks guys will keep the board inform

 

what green light, and what door switch is he referring to?

 

the green light on the power window switch on driver side

 

I can see a door switch preventing the car from going into sleep mode, but I can't imagine that a door switch is responsible for drawing 11 Amps.
11 Amps at 12V is 132 Watt. You could warm the cabin with that kind of power drain! Or put the fans on max power. Or it can turn your head and tail lights on with 132 Watt. Are you sure that's what the technical manager said?
