I can test the function of mine with my Foxwell scanner.
I run the RPM's up to I think it is 1500 RPM and I watch the exhaust cams jump in advance by 25 degrees.
Or I go to the testing functions and actuate them with the scanner and The engine responds differently so I know if they are working or not.
Your mechanic should be able to verify if the actuators are functioning or not 
As you stated:
There are wear pads on the actuators so if they are worn out the actuators can be fine and still not advance the cams properly.
Wear pads are cheap actuators expensive.
Hope this info is of some help.
Keep us posted with the out come. |
You are correct, talking about the VarioCam actuator. He’s going to test the actuator function today and confirm there’s a cam position mismatch before moving further.
