High Oil Temperature
Compare to other engines, the N55 engine runs at a pretty high oil temperature, about 115°C (240°F). Most cars I have driven run at 90°C, even after hard driving, they won't exceed 95°C.
If I use Sport mode the car would lower its temperature to 90°C, but the transmission shifts late in automatic mode or I have to use paddle shifters, they are not something I want during my commute. I probably shouldn't be concerned about the high oil temperature since the car is designer that way, but is there a way to enable better cooling while shifting the car at a relatively normal rpm? |

The only time I saw the oil temp creep up to 240F was while playing at the skid pad mostly in first and second gear. |

I'm in the US, so my dash gauge might be different than yours. As well as I never drive in comfort mode. But mine sits around the first tick. 1/4 line. I did have bm3 hooked up today though and was playing switching between comfort and dsc off to see the cooling difference. Just in my city with light driving and stop lights. Noticed coolant would get a few degrees F higher in comfort. But, like I said, I was only playing around and don't even remember the values. To answer your question though. Sport, Sport+, and DSC Off are the only modes with increased cooling. I don't think either of them have the shifting experience you're looking for, though you can try and see. Additionally, if you push the car harder in comfort mode, the increased cooling will kick in. Not the answer you want, but that's the way it is.

Just saw this and thought of you. I wonder if this would lower your temps while in comfort mode.

The thing that I question is the description says "increases flow to your fender mounted engine oil/air heat exchanger"
So let's say they are talking about the auxilery oil cooler in the bumper. The question then comes... is that oil cooler blocked off while in comfort mode. I think it might be. If so, then this won't do anything for OP. |
