Skoda Karoq Coolant Loss

Low coolant on a relatively new Skoda Karoq is definitely concerning. I had a similar issue with my Seat Leon, though it took longer to surface. Have you checked around the water pump area for any signs of a coolant leak? Also, inspect the coolant reservoir itself for cracks, especially along the seams. Any visible coolant residue anywhere?

Thanks for the quick reply! You mentioned a defective plug connection on your Seat. Was that causing the coolant level to actually drop, or was it just triggering a false low-level warning?

In my case, the defective plug connection was causing a false low-level warning. The coolant level itself was fine. But given that you're actually losing coolant, it's less likely to be the same scenario. Still, the error code might be misleading you to think of much bigger problems than what the fix could be. If you are losing coolant I would check what I mentioned earlier, or get yourself booked into a workshop so they can pressure test the system.

Thanks so much for the input! Dropped it off at the workshop this morning. Turns out it was just a defective plug connection on a sensor related to the coolant system, exactly as you suspected. They're calling it fixed for 95€. Appreciate the help!
