Hello!
My Tiguan turned on the temperature light when the car was cold (I had just started the car in the morning), I turned off the car and checked the coolant level and it was normal and pinkish in color as it should be.
I started the car again and the light went out. However, I noticed that the coolant suddenly became darker.
I turned off the car and didn't use it anymore, when I opened the reservoir, I noticed oil mixed with the coolant.
I checked the oil level (it was ok) and the gauge doesn't appear to have any coolant mixed into the engine itself.
I suspect that the heat exchanger (oil cooler) has broken or something with its sealing gasket.
My tiguan is a 2.0 TSI petrol, 200hp, 4x4.
Any idea what might have happened? My main suspect is the radiator and oil (yellow part in the photo in the diagram).
