Code P105B MINI Description

On the Valvetronic VVT (Variable Valve Lift Control), the variable valve gear reduces fuel consumption by adjusting the stroke of the intake valves. An electric motor is used to drive a worm gear that moves the eccentric shaft. The eccentric shaft uses intermediate levers that change the effect of the camshaft on the rocker arms. The Diagnostic Trouble Code (DTC) will be set when an excess current is recognized on the high side or low side transistors.
