Default Oil overfill, Remove Oil Warning!

I need the boards help yet again. I had a different shop, that I thought was going to be a great alternative, change the oil and service my granddaughters 2010 Q5 3.2 engine this past Monday. The place I used in the past used 6.6 qts of oil (KENDALL GT-1 EURO 5W40 SYNTHETIC OIL) at change, which I assume is the 7 liters needed. The monitor and dipstick read correctly at the time. The new guy used 7 qts. ( Same type oil), Now I have the Remove Oil notice when I check the oil monitor.

My question, is the approximate 1/2 Qt overfill cause for alarm and immediate action? I will take her car to the Audi dealer for a couple of recalls this coming Monday and can have the half qt removed if necessary. Or can I just leave it in as it burns about a half qt every 5k or 6K miles? Also, does anyone have an amount I should expect to be charged for the removal?

I read this from a post by James R.
"Furthermore, overfilling the engine that grossly can damage the vehicle...the crank can slap at that oil beating it into a froth causing lubrication to be compromised. It can get whipped into the crankcase ventilation system spreading oil all through the intake tract and possibly to such an extent as to damage the three way catalyst or the O2 sensors...

Is he talking about a car grossly overfilled with oil, or do these dangers apply even to a 1/2 qt overfill?

As always, I appreciate any input you may have.

First, it takes a few starts/stops/driving distances (up to 30 miles) to average out the oil monitor readings and it may just not register the overfill in a day or two.

Second, if you do the math. One half a quart of oil is approximately 9 cubic inches in volume. Assuming that the oil pan is 10 x10 inches, 100 square inches, probably larger is real life.
Then the overfill oil height increases approximately 0.1 inches, negligible! I personally wouldn't worry about that increased oil level with my Q5 at all. There is no way that the crankshaft would hit the oil and cause foaming.
Oil sumps are designed to handle overfills.

The dealer will do it, most likely over removing the amount of oil, charge you for new oil to refill it to the correct level, charge you labor at $100/hr., shop towels, oil disposal fees, etc..

No relax. 1/2 qt.is not going to do any damage.I'm a tech in case you think I'm guessing.

Thanks to you both, Bob and Murry. That tells me all I need to know and is a relief to we who do not know much more than jack about the mechanics of an engine. I don't have the car now but will Sunday and will check the dip stick as well as the monitor. The added dip stick and upper center console tray is the extent of the modifications I have done to her Q5, which tells you about the extent of my expertise.

Another reason to order a dipstick and manually check the oil, especially after the dealer touched the car for any reason!
