With a lot of help from the members of this forum, I completed a low mileage engine swap from a 2010 BMW E60 M5 to a 2006 BMW E60 M5. I started in early 2020 and completed in fall of 2021. So, it took about 18 months. I know a long time, but I did it in my spare time using only hand tools.
I have been enjoying driving the car last fall, a little this Winter, and this spring.
Last week I got the low oil indication on the dash. So, I added a liter of oil. The low oil indicator went away.
Afterwards, the dash displayed an oil level of '1.2'. Later the same day, it started displaying '1.1'. But I did not know what it meant because I had not brushed up on how to read the display on the dash yet. Most car dashes display oil levels as being low, high, or in the desired range, as do dip sticks.
This past weekend I was doing some spirited driving. After I slowed to mere human speeds, the engine started running rough and I got the engine malfunction reduced power indications on my dash and on my navigation display. The engine is especially rough at idle.
It was about this time I brushed up on the oil level reading for the E60 M5. Everything I read said it should be at a maximum of '1.0'.
Naturally I am now concerned about the possibility that I may have damaged to the engine. So, I pulled the codes with ISTA. I have code 2B46 - Cylinder 5 misfire.
A few questions:
0. Does this car have a high oil level warning?
1. Is it possible to damage these S85 engines with only .1 liter of oil over the maximum and this is merely a coincidence?
2. Is it possible the misfire is unrelated to the oil overage and just a coincidence?
3. Is the proper procedure to troubleshoot the cylinder 5 misfire to swap the ignition coil and/or spark plug between cylinders 4 <-> 5 and see if the fault code moves to cylinder 4?
4. Should I immediately drain the excess .1 liter of oil?
Thank you.
