I was thinking that, that if he changed the filter, that would work, only thing is it's kinda bothersome to think of the car running with out any oil in the filter for some time before it gets primed. Depending on where in the oil circuit the filter is, the oil pump may be sucking air for a bit of time before it gets oil to the parts that need it.
Don't full race cars have dry sump systems?
I don't mind if my cars are over by that much. As mentioned above, running race cars a quart over is not an uncommon practice either.
I wouldn't take any corrective action.
Yes, but they have windage trays, baffles in the pan and crank scrapers to stop oil from splashing around the crankcase. The smart ones do. You can lose a lot of ponies to this, enough to put you at the back of the pack.
you absolutely can pre-fill an oil filter prior to installing it on a car even if the filter is installed upside down. Screw Can Oil filters have check valves to prevent the vast majority of the oil from leaking out, that's by design. The older design Oil filters where the filter and holder are separate pieces and you only recycle the actual paper filter itself, most of those are installed such that the filter is on the bottom of the engine, not on the side. Top and side mounted oil filters should be "can" type as they have check valves to prevent oil from leaking down into the engine.And don't listen to people who have no practical knowledge that there are cars out there with oil filters that mount sideways or even upside down on the top of the motor that can't be pre-filled with oil. Sucking air until the oil gets to the pump... Nearly unbelievable.
I also drive a AWM 1.8T passat. My guess is either
-The shop fill the whole 5L(or Quarts) jar into it, normally need 4.5
or
-They used the smaller version of oil filter which is 1/2 the size of the suggested filter so more oil in the pan
AWM burn shit load of oil anyway, nothing to worry about.

I don't think the anti-drainback valve will help when changing the filter, since it only blocks one side of the flow path? Isn't oil still going to run out of the center hole?
I think that's just unnecessary, though.
I know people who would disconnect their ignition and crank the engine over for 10 seconds after changing the oil. This was supposed to prime the system and fill the oil filter.
People often seem to think they know better, I guess.
