Background

In certain driving cases, the CHECK ENGINE lamp comes on and diagnostic trouble code P0244 is detected. The reason is a turbo boost pressure higher than the permitted limit value which is detected by the engine management system. In turn, this can cause the engine to be lowered to basic charging pressure. New software can rectify the problem according to the following.
