This BMW f10 520d 2010 had a short circuit on the gearbox wiring because it fell on the particulate filter and due to high temperatures it melted and made a beautiful short circuit, the wiring was repaired by other shop and after the repair the car no longer enters sleep mode , and discharges the battery overnight, after an investigation I have found line15 wake-up from CAS had permanent voltage (terminal 15 wake-up have voltage only with ignition on ) , after a check I found the transistor from CAS module that deals with powering the terminal 15 wake-up line is shorted and sends permanently voltage in line 15Wup, after replacing the transistor everything returned to normal. the transistor has shorted due to that short circuit on the gearbox harness. Officially for this malfunction / problem the CAS module is replaced with a new one because is not repairable , But unofficially I fixed it!
