There are plenty of threads here on how variocam operation can be tested with the durametric or similar diagnostic tool, but I wanted to make sure they work before putting the engine back in the car. So I used a simple borescope camera to capture the switchover of the variocam units while the engine was driven by the starter on my work bench. I inserted the camera through the hole for the green plug over the intake camshaft, on the scavanging pump side. I used 12V to switch the solenoids on. Here are some pictures, looks like they both work fine
Ths is just for guidance if it`s unclear what we are looking at:
Variocam at bank 1-3 at rest:
Variocam 1-3 actuates:
Variocam bank 4-6 at rest:
Variocam 4-6 actuates:
