Hello,
I just buy a new Continental Supersports from 2010, and already a new problem with this car, the code 02439

Merci beaucoup

 

Parking brake - loose wire , poor connection of the plug on the motor at the back of the rear discs .
check the connections clean some guys nip up this and the fault goes after a few start / stop cycles or you clear it with your VDS system.
