upra Leon eHybrid 245 - Faulty Coolant Temperature Sensor

[Struchka12]

Hi everyone,
I’m looking for advice and feedback on a situation with my Cupra Leon eHybrid 245hp. About 2 weeks ago, I received a warning: “e-Drive is not working correctly, please visit service.” (Photo attached.)I took the car to the official Cupra service center, where they performed diagnostics and found a faulty coolant temperature sensor 1 (internal code 2070044/6). They explained that fixing it requires a lot of work because the high-voltage battery must be removed to access the sensor. The total repair cost is approximately 3000€, which seems very high for a sensor replacement. My Questions:

1. Has anyone encountered this issue before? I’m curious to know if this is a common fault or if there’s a pattern with this sensor failing.
2. What happens if I don’t repair it? The service center said there are no immediate limitations if I keep driving with the error. However, I’m concerned if this could cause long-term issues for the battery or drivetrain.
3. Is this sensor only related to the high-voltage battery? I have insurance from the car dealer, but they refused to cover the repair, saying it’s a battery-related issue. Is this correct, or does the sensor impact other systems as well?

Any feedback or suggestions would be appreciated. I’m trying to understand if this repair is truly necessary or if I can delay it without damaging anything further. Thanks in advance!
