I don't know that much about the VW engine but my engine only has 60-70 lbs at start up and drops to 35-40 at idle when warm. When hot it drops a bit further but I don't remember how much. At speed I see 60-70 psi. I'm using 15W-40 oil. I do have an oil cooler with thermostat that directs some of the oil to the cooler but not all.
I take my pressure readings from a port on the oil filter bracket that bolts to the side of the block as the oil re-enters the engine. This is after the oil is filtered and cooled.
