540i - cooling system question.

My '97 540i had a thermostat replaced by the local dealership this week at the same time I changed the oil. They had to bleed the coolant line after that, but, obviously poured too much coolant into the tank, because the dipstick is all the way up with the cold engine. On that model, as well as few others, it's supposed to be flat with the plug hole.

I started to notice now that the temperature gauge needle is slightly past the middle point, but I can't say for sure if it was precisely in the middle before the thermostat was replaced.

My guess is that there's nothing serious to worry about, just want to confirm with the rest of the folks in this forum that my engine temperature is normal which means that the cooling system is working properly.

I went into OBC Test mode, under "Test-07" it showed 110 degrees Celcius on a hot engine, and after 5 minutes or so it was 105 degrees. Is that temperature normal for a 8-cylinder engine? Thanks.
