I didn't realize there was so much blue in dolomite silver. It looks fantastic and reminds me of the light blue on the E39 M5 in that photo. I definitely don't see enough of it, the black accents work so well with it.

Is it normal to see the temp gauge for over 194 ? In my 14 Cayman the 194 doesn't budge, but I saw 198 and 200 pop up while the car was sitting in traffic. Once I started moving it goes right back down to 194 - just wondering if this is normal for the Macans to fluctuate a couple degrees

Normal, the actual range of engine temps (for the 2.0) is 195F to 210F, but in stop and go traffic, it will climb and peak at about 236F.
But, the Macan coolant gauge on the dash is factory programmed to "dumb down" the displayed temperature range, versus the actual engine range, which makes the gauge display "194F" under almost all operating conditions.
You can "recode" the Instrument Cluster to remove this "filtered" display behavior, and have it display the true actual coolant temperatures. (Like I did, where I have observed the actual range from 195F to 236F)

Well, that certainly begs this question: I just ordered an icarsoft V3 scanner and it will be delivered tomorrow. How can I code the coolant display to show actual temperature. Thanks!

To linearize the engine coolant temperature gauge, these are the steps for my Launch X-431 “Torque III”, on my 2019 Macan Base.
1)Connect your Launch scanner, start the X431 software, plug into your OBD2 diagnostic port.
2)Turn ON the ignition, but don’t start the engine. (Don’t depress brake pedal when turning the key)
3) Select “Diagnose”
4) Select “Porsche”
5) Scroll through the list of modules to find “Instrument Cluster”, then select “Enter” for it.
6) On the Instrument Cluster menu, select “Code / brush hiding”
7) Select “Rule Coding”
8) Select “Coolant Temperature Characteristic Curve”
9) You will now see a table of 8 “X” values (“X1” thru “X8”), and if you scroll further down, 8 “Y” values (“Y1” thru “Y8”). The X values are actual coolant temp, the Y values are what the gauge displays.
10) Write down each of the X values, and each of the Y values.
11) For each Y value that is different from the corresponding X value (X1 compared to Y1, X2 compared to Y2…..), select each different Y value, a data entry box will pop up, and then enter a new numerical value for it, which is equal to the corresponding X value (ie change Y3 to equal the value of X3).
12) When you are done changing the Y values to be equal to the X values, press the “Write Code” button at the bottom of the screen.
13) Then exit the Launch, and turn off the ignition key.
14) Unplug from the OBD2 port.
15) Done

Also, was able to reset my oil service and interim service lights after servicing it . The new one seems to have a battery function that mine doesn't have.

When I said "module coding/programming" I mean:
Macan Coding - Page 20 - Rennlist - Porsche Discussion Forums
To code/program control modules the scan tool must have a "bi-directional" feature.
This is not the same as the ability to "code" the battery.
