Battery Drain due to sleep mode not activating

[sbhudia]

Hello,

I currently own a BMW e60 530i AUTO Saloon and every now and then the car seems to be draining the battery when left for 7-8 hours parked.
When the car is switched off everything in the car swithces off except the light on the Gear stick on the Park indicator.
This suggests to me that the car is not entering the sleep mode and some of the electrical modules are draining the battery.

Has anyone else had these problems and is so could you please post a solution

Thanks
