There are two sound insulation panels under the car. You will need to remove the front one to do an oil change. It's only 4 screws...

The panels are costly to replace so don't lose them!

Careful! Overfilling is MUCH worse than underfilling. If you overfill, the oil will foam. NOT GOOD!!!!

Suck some out the dipstick tube. You could suck a half-quart out with a turkey baster and a bit of tubing.

If the oil level is so high that the crankshaft and connecting rods are actually in the oil, they will beat air into the oil just like a cake mixer would. Foamy oil does not work well in plain bearings; in a worst-case situation, they could be damaged. In your case, half a quart over is probably not enough to cause that problem but you should suck the excess out anyway as penance so that you will remember next time.

Overfilling a diesel with oil can do multiple bad things, firstly foaming the oil and ruining bearings, secondly causing oil to get sucked into the combustion chamber and cause a run away engine.

Keep it at the max mark or below! Ideal is halfway between the marks.

Hi guys. So basically I became lazy and decided to put about 1500 miles on the car since I overfilled the oil. I went back and looked at this post, got paranoid, and went to suck out the excess oil. When I went to check it however, the oil was right at the halfway mark where it should have been. im sure i checked it properly before, and it was definitely overfilled, about halfway up the little red marker. is this normal? im assuming looking under the car for any leaks is pointless, since the panel would catch any drippings. The car runs great though.

You most likely have a few oil leaks. The oil pan gasget is probably the worst offender. Or maybe the IP oil gasget Or both like my car

I removed those sound insulation panels from my 190D and haven't missed them. Since having my injectors rebuilt, the engine purrs nicely without any nailing and the noise level is not objectionable to me at all. (Even though my hood pad is mostly gone, too.)

Those panels were in the way and they tend to catch dropped tools and fasteners when working under the hood, sometimes making retrieval difficult.

As for oil changes, I use a MityVac to remove the old oil through the dipstick tube. Works fine, and I find the whole oil change regimen easier and less messy, vs. draining out the bottom. I believe this was actually the factory-specified method, IIRC.
