Can someone help clarify this?

 

There should be one on each bank

 

I'm noticing when searching that '07 or earlier engines have both sides, does this indicate '08-'10 have only one side?
Anyone else with only driver's side valve?
Looking into more detail in parts system:
"Please check on your own whether the
cylinder head cover is equipped with a
pressure control valve, then please
also observe BTE113259"
Looking at valve covers
Cyl.head cover w/o pressure ctrl.valve ZYL. 1-4 p/n 11127563474
Cylinder head cover ZYL. 5-8 p/n 11127522159

 

Seems only the driver side has the valve. Attached is the pic of the cars who does not have the valve on the right side

 

For the 06 to early 07 they use a vent pipe on the right side.

 

I read how one guy said he thought he only had one pressure regulating value, but he found the other one inside a passenger-side hose.
