Mark X automatic temperature control issue

Oh man, I know that frustration! I had a similar thing happen with my Mark X. The HVAC was just completely borked. Is the temperature reading completely off, or is it just not responding to adjustments?

The temperature reading appears to be static and unresponsive to adjustments. Could you please elaborate on the specifics of the issue you experienced?

Yep, sounds like the exact same issue I had! I spent ages fiddling with it myself, checking fuses and whatnot, but honestly, I'd just bite the bullet and take it to a workshop. It'll save you a load of headaches in the long run. They'll diagnose the sensor and fix it properly.

I appreciate your advice. I took the vehicle to a workshop, and the issue was indeed a faulty connection to the interior temperature sensor, as suspected. The repair cost was 95€. Thank you for confirming my suspicion and recommending professional assistance.
