My wife's 328 has the electronic dipstick and I honestly love it. I've always hated regular dipsticks, I have found them to be very inaccurate and inconsistent in a lot of cars I've owned and I honestly don't even check the oil in my other cars anymore. When I drain the oil I measure how much comes out so I know how much topping up needs to be done on the next OCI. This method has worked well for me for at least the past ten years now.
My 2000 MB E430 has dipstick and on-board oil level checking. I prefer the actual dipstick for reason:
When I change oil in Fall I prefer slightly less than full by about 1/2 quarts, the sump is 8.5 quarts I use 8 quarts for a little faster war up in cooler winter temp(not as cold as snow belt but cooler than 80-90F).
I early summer I would like to have full 8.5 quarts in the sump to keep the engine a little cooler in summer heat, with dipstick I now exactly how much I need to add.
-----------------
Before I change the oil with a fluid extractor I check the level on dipstick and verify that with level in the Mityvac container. If the level in the Mityvac is less than what I saw on the dipstick I would try to extract more. And I filled the sump with 8 quarts if I could siphon all used oil. In 10-13k miles my E430 may use up to 1/2 to 1 quart, I don't rely on how much I extract from the sump to fill the engine with same amount.
Yes, the on-board oil level check of my 15 years old E430 doesn't tell the exact amount, it only says: Add, Okay and Overfill.
But in general, electrical sensor of any kind is know to fail after number of miles/years, replacing those sensors are costly compares with dipstick(s). I truly believe in the saying "if it works don't fix it" for the oil dipstick and tube.
I do embrace new techs if it let me do my work better and more efficient, Mityvac 7201 is the kind of new tech I like compares with the old way of oil drain from bottom of the engine.
