Thanx for the DIY. I used this DIY to fix the dealer overfill. The dealer overfilled my engine by .5 liter. As soon as I drained the front oil sump, my reading is perfect.

The last technician that worked on my car didn't even drain the front slump hence the overfill. I know this because when I unscrew the M6 plug, I heard the loctite snapping. THis is a sign that the drain plug was never removed.
