Electrical - battery drain

[michael lang]

Just out of curiosity, does your car have power seats with memory? I don't know 986's that well so I don't even know it that was an option. If your car does, and you genuinely feel like the shop has misdiagnosed the problem I'd be inclined to agree with what Larry had suggested. Somewhere in your car is a control module staying awake. I'd be leaning towards one of the door control modules, it memorizes seat positions, operates the seat motors, mirror motors, & window motors. It is likely that one of those is not "going to sleep" after the car has been turned off. Just a guess, again I don't even know if your car is equipped that way.
