Hi fellow Macan Owners!
I've been reading the forum for a while but never register to post, so this is my hello!
I own a 2016 Macan S, 43k miles, and have been behaving great, up until recently, it suffered from a pretty bad coolant leak. The plastic coolant hose under the intake bursted and wouldn't hold any coolant at all. My mechanic did a replacement, and now everything seems to run fine.
I did become a lot more suspicious of the coolant system's performance after this incident. I'm worried that the underlying issue may still be there. So I took half a day and gathered a ton of observations of my car. I also purchased a ODB2 data plotter and was able to read the engine coolant sensor directly instead of relying on the idiot gauge on the dash.
During normal driving conditions in the city, my coolant temp according to the dash is 200F, but the sensor via ODB2 reads around 220F, oil temp on dash reads about 200-210F under this condition. As soon as the car picks up to freeway speed, the coolant temp drops to about 200F and oil 195F ish. If I am sitting idle for a long time, the ODB2 read coolant temp would hangout around 225, and oil temp around 210.
I also noticed that once sports mode is activated, both coolant and oil temp drop 10-15F ish within seconds.
These temps seem a little bit toasty in my brain. Clearly, the car is able to regulate two different setpoints with the toggle of sport mode, which leads me to think the thermostat is fine. Is this within what you guys have seen on your cars?
Cheers,
Dennis
