it’s not happening on the 991.2s because they don’t fail. Porsche completely revised the part for the .2

Did you get resolution to #2? Have mine for 18 months now, and took a long Covid escape drive to Florida from NY. When I left NY checked oil and was normal in middle of gauge. Checked again mid trip and was still OK. When I got further along level was at upper max limit and then ultimately got to a point where it said reduce oil! Never in my life have I heard of oil increasing. Expand due to heat, OK but oil level is only read at operating temp so how? Further A service done in May and haven’t needed to add any oil so how can it be?

I dislike the absence of a dipstick on the m176 series engines, but MBUSA hired all them to work in customer service. Regarding the electronic oil sensor/indicator system, it's less than reliable. It's not a simple mechanical sensor like used for fuel, as a mechanical sensor would sludge-up and stop working. Others have probably noticed or read in the owner's manual that you can't simply start the vehicle and obtain an immediate oil level indication. The engine has to come up to operating temperature and pressure. Last winter, I was waiting for someone and sat in my G550 for about an hour with the engine idling. I did not receive any panel warning, but when I checked the oil level, it indicated I was at maximum level, probably because the engine was at normal operating temperature, but circulation was not occurring at normal operating RPMs. I change my oil every 5K (yeah, I know it can go 10K), and the last 2 changes have netted 9 quarts in the 2 jugs. I'm guessing he other quart was left in the drain pan, filter and engine, or was burned off. I pour in 10 quarts, and after driving a couple miles, the oil indication is at mid-scale.
