Hello to everyone! I recently bought a Mini Cooper 2008 1.6 (it's not the turbocharger) and it introduced me the fault code P0015. I already change the oil, the solenoid valve and check the cam sensors, and they are fine but I keep presenting the fault code P0015 I do not know what else to do, the cables are fine, and the voltages. Somewhere I read it could be the vacuum pump that is possibly failing, and that's why it presents me with that code. Does anyone have any reasonable ideas?
