|What is P1078 MINI code meaning?

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. Monitoring of servo motor overload; The VVT servo motor temperature is calculated in the Digital Motor Electronics (DME) using a model. The first stage occurs when it heats beyond a warning threshold. This is 190°C (VVT motor temperature) and causes the VVT to revert to operation in its emergency mode. If the VVT motor were to overheat even further, the VVT system would be completely deactivated upon reaching the deactivation threshold (200°C VVT motor temperature).
