This is a flag. Why is the timing moving? It shouldn't. Makes me wonder if the tensioner is not set up properly.timing belt replace about 30,000 miles ago 100,000 mile kit.........timing has retarded twice since new timing belt.....will check timing belt and tensioner

And finding nothing wrong and then putting the cam plate back in upside down? (Only jcrews knows what I'm talking about and that comment is not directed at anyone but dumb me.)I received a log and timing is not advancing, indicating a timing solenoid failure or piston binding. I requested some more info, but it'll most likely come down to pulling the pump and inspecting it.
Wow, quite wrong.There are only 4 Bosch shops in NA that can service and calibrate these pumps. Wisconsin, Oregon, New York State, and South Carolina.
