Hello and good morning,
it's now 7:10 in Germany and i'm back.
But i have to go to work now.
To test the adjuster solenoid of the camshaft tension element electronically a.f.a.i.k. you'll need a Durametric or PST (Porsche system tester) diagnosis system.
I attached some infos concerning the components and diagnosis. Maybe this gives a better understanding.
I don't agree with Gelbster about the noise. This can be a single valve / hydraulic lifter – believe me, it can be this loud.
The question is why it could fail in a wake of an AOS failiure? Maybe hydrolock. If there was enough oil in the cylinder to prevent the valve to open the hydraulic lifter could be harmed.
Another question. In the video the noise i'm talking about is starting at around 00:20. Is it always the same that the noise comes up some seconds after the engine starts. Or does it sometimes start directly with that noise?
Regards, Markus
