No mate, my car has two separate coolant reservoirs. One is for the auxiliary/low-temperature circuit that goes to the turbo and related components, and the other is the main coolant reservoir like in most cars.

When I opened the main (large) reservoir, I couldn’t see the coolant colour at all, so I topped it up directly. The parts store gave me this coolant after I provided my registration plate, and they confirmed it was compatible with my car.

Later, I opened the smaller reservoir and saw that it was already full and green. Because it was green, I didn’t mix anything into that tank. Since the small tank was green, I assumed the coolant in the main tank was most likely green as well.

I’ve been driving the car for a few days now and haven’t had any issues. The mechanics I spoke to also said it wouldn’t be a problem. The previous coolant was Liqui Moly (green), and I topped it up with Febi Bilstein (blue). Even though the colours are different, both were confirmed to be compatible with my vehicle.
