I own a 2018 Audi Q2 with a Diesel engine and 58,750 km on the clock. I'm experiencing a problem where the fan doesn't turn off after the engine is switched off, which drains my battery unless I unplug it. The temperature doesn't rise at all, and the check engine light is on. Once I reconnect the battery, the car runs normally until I park, and then the fan kicks in again. Each time, I have to unplug the battery (minus). What could be causing this issue, and how can I fix it?

Check if the coolant temperature sensor is functioning properly, as a faulty sensor can cause the fan to run continuously. If the sensor is defective, it may send incorrect signals to the fan, causing it to stay on. Inspect the sensor for any visible damage or loose connections. If you're unsure, consider having a mechanic test it. Let me know how it goes or if you have any further questions!
