Coolant loss on a 2013 Porsche Cayenne Diesel is rarely minor. We had one towed in after it dumped all its coolant and lost the drive belt, caused by a failed rear coolant fitting.
Repair included a new fitting, new belt, and system pressure test.
If you notice coolant smell, low level warnings, or residue, get it checked early to avoid bigger. https://dartauto.com/blog/porsche-repair/coolant-loss-and-hidden-damage-on-a-2013-porsche-cayenne-diesel
