Help us help you. By posting the year, make, model and engine near the beginning of your help request, followed by the symptoms (no start, high idle, misfire etc.) Along with any prevalent Diagnostic Trouble Codes, aka DTCs, other forum members will be able to help you get to a solution more quickly and easily!
What year and engine? What's the oil condition? Check the connector, is the pin fit good or to loose? Not very familiar with euro but do there require clearing the adaptions in the ECU after parts replacement? Monitor the data and compare commanded cam position to actual cam position
