Hi all

I've been checking my 330i's coolant temp on the dash out of curiousity recently. It seems to have an issue and not reach operating temperature despite returning decent mpg for the type of driving I do.

On cold start the car will quickly reach 92c, it then starts lowering itself to about 75c, rising to 85c then back to 75c and so on. Occasionally it will go back up to 95c ish then back down to 75c.

Despite still getting a decent 34mpg over 415 miles of mixed driving, I'm worried that I might be causing damage to the engine when redlining it with 75c coolant.

Can anyone else with a 330i share their typical coolant temp with me?
