Variocam actuator ?

[mtimmy]

I keep getting the 1539 code, I tested the Voltage supply B+ wire and the triggering wire for ground/continuity but couldn't find any faults on it.

Tested with the durametic tool with the camshaft adjustment on bank 1 and bank 2., when activated , either bank 1 or 2 the idle went unstable, it tells me that the actuator is working (I can rule out a bad actuator?)

I have replaced the bank 2 hall sensor about 6 months ago ., (a bad install maybe)? very frustrated, couldn't figure out what is the problem.

....

can't think of any thing now..

btw any body have a photo of the actual variocam actuator because the plug type from ALLDATA dosen't look the same as the one I find in the car., I might be testing a wrong thing after all.

Potential causes:

- Open circuit in triggering wire.

- Open circuit in B+ supply.

- Actuator faulty.

If everything electrical tests okay - then you have a bad actuator.

Yeah., I know from the manual ., it say if every thing tested out okay replace actuator, but I tested it with the durametic the actuator actually did shift... will it still be a bad actuator?

Is there a possibility that the actuator did shift and advanced the timing to cause the rough idle however not enough for the cam sensor to tell it advanced enough timing?

Potential causes:

- Open circuit in triggering wire.

- Open circuit in B+ supply.

- Actuator faulty.
