Anyone else aware of this function? 2 Quote Share this post Link to post Share on other sites
Jacko 2158 Report post Posted July 21, 2020 (edited) Yup, pretty clever beasty. The oil pump in them is clever from an engineering standpoint too, all mechanical and able to vary its output as needed. Edited July 21, 2020 by Jacko Quote Share this post Link to post Share on other sites
qube 3570 Report post Posted July 21, 2020 how hot does your 130i run generally? do you find the above to be true? basically meaning it fluctuates between 80-112 degC Quote Share this post Link to post Share on other sites
Jacko 2158 Report post Posted July 21, 2020 (edited) It fluctuates a lot, between 80 and the highest ive seen is like 105, you can watch it change modes in realtime during an italian tune up (where it drops temps the more "italian" the tune up ) Edited July 21, 2020 by Jacko 1 1 Quote Share this post Link to post Share on other sites
M3AN 4016 Report post Posted July 21, 2020 That's quite interesting, I've thought mine runs unusually low (~90C) even when driven hard, will have to have dive it slowly for a while ? to see if it warms up more! Quote Share this post Link to post Share on other sites
GorGasm 563 Report post Posted July 21, 2020 My N55 runs like that. Runs hot when cruising around. Quote Share this post Link to post Share on other sites
