Are you sure you are looking at the right Dur values? There is a cam DEVIATION value and there is the actual angle value of the cams. The actual value varies slightly at idle but then will go up wildly when the car is accelerated.

If you are absolutely sure you are looking at the cam deviation values, then don't even start the car without looking at the filter,as Meir said. If you were looking at the actual value, then switch to the deviation,which shoould be a dead flat line at idle.
