The 1.6L solenoid is located right next to the wastegate actuator it controls. davidjohnson7743. not too sure if the 1.4;s are the same. leaking injector seals cause contamination of the oil, contamination blocks up the oil pathways and particularly the small oil feed/return to and from the turbo. usually a car killer as the entire engine needs stripped and cleaned to surgical standards and new turbo fitted.
