    Hello everyone

    I parked my 458 for a week and i started it today. The Dashboard temperature is -20 while the real is +30.

    The AC compressor isnt working too! Anyone face the issue before?

    ist a battery issue or fuse?

    I drove the car. I restart it. All is normal except the temperature and when i drove it the temperature became - -.

    Thanks

    Disconnect the battery and then follow the reconnection procedure in the manual. Usually that clears odd-ball stuff like this.

    Outdoor temp sensor is in the driver mirror, no? Sensor may be defective or unconnected...

    Maybe you are right. I took my car for PPF wrap and they remove mirror and took it back
    So it might not be connected properly.

    Or they over used the gun heat direct to the sensor.

    I will check properly


    I will tonight. I connected the battery maintainer for the day. Maybe disconnecting the parts and reconnecting it needs to clear the faults.

    Hello everyone,
    Regarding the temperature manner

    I took the car to specialised shop:

    1 - they diagnose the car and due to computer gives fault reads. It shows the AC actuater sensore is not working which requires extra work to solve it.

    2- i asked the guy to check the left side mirorr connection because the PPF shop removed the mirror and reconnect it.

    After 1 hour, we found that the connection 2 cables. ( Black cable - coloured cable ) connected wrong. We re connect the black with black, coloured with coloured cable and it work!

    Temperature is correct
    AC is cooling due to correct reads
    Mirror control works well

    Glad you got it figured out. It is for reasons like this why PPF is a double edged sword. A detail shop should not be disassembling and removing parts IMO. If damage had occurred it would place the owner in a poor situation between the dealer and the detail shop souring both relationships. Parts like side mirrors don't need to be removed for PPF.

    Yes I agree but with removal, you get a better installation without showing the cut lines.
