Hello .I recently bought a Skoda Superb MK3. After a few days the fan stopped working. I changed the blower fan but it still doesn't work (the one on the car was already changed with a aftermarket). I checked the fuse and it's ok, I bought another resistor and it still doesn't work. I checked the wires and they have 12v. When I press the AC button the light doesn’t appear. On the diagnostics I found these errors. What could it be? Thank you

And Acc not working, park pilot error , start /stop not working. U112300 error appears on multiple functions.

Welcome to the forum.

Has the battery been fully load tested? This should be the first thing to do.

A failing battery is definitely a prime suspect for ACC, Park Pilot and SS errors - as are failing ABS wheel sensors.

U112300 is a generic code for communication errors between control modules.

If the battery definitely tests as fully functional, faulty wiring, connectors or failing sensors can cause this DTC.

Have there been any modifications made, I.e. changed steering wheel, etc?
