Seat Altea climate control issues

Sounds like a familiar headache! I had a similar issue with my Seat Leon. The automatic temperature control went haywire. The temperature reading seemed totally off, like it was trying to cool the car to the arctic in the middle of summer. Have you checked the sensor connections? Sometimes it's just a loose plug.

Interesting! When you say 'similar issue', did you also have a specific error code stored? And did you manage to fix it yourself, or did you end up taking it to a workshop?

Yes, I had an error code too – something about implausible temperature reading. I fiddled with the connections, cleaned them, but no luck. Eventually, I had to take it to a workshop. They confirmed it was the temperature sensor itself. Think of it like a dodgy thermostat in your house; if it's not reading the temperature correctly, the whole system goes haywire. If you have checked all the connections, you might want to get it checked at a shop.

Took it to a shop as you suggested. It was indeed the temperature sensor and a dodgy connection, just like we thought! 95€ later and the climate control is back to its old self. Thanks a million for your help!
