    Random Electrical issue St3 mk2

    Hi guys,
    Weird issue i have random electrics out, windows, mirrors, heater/climate control and bonnet open message on dash, temp gauge blank and frost symbol showing.

    Ive checked fuses and seem ok, is it likely a specific relay?

    Ive had a few quotes from auto electric companies and its not looking cheap.

    Cheers

    How old is your battery. Random, weird things begin occurring with the ST when the battery starts to go bad.

    Gonna have to agree with @beretta96 on this one. My buddy's ST would randomly start and then lose all Interior electronics. It even started throwing PCM error codes. It turned out the battery terminal, even though it was tight and wouldn't move... Wasn't making a good connection. We replaced the terminal and boom, car started every time. Also check the mega fuses in front of the battery box.

    Ive tested fuses and mega fuses, they seem ok and also tested battery, it reads as just under 12v off is that a sign of a bad battery? I just read it shouldnt be lower than 12.6v off. I bought the car nearly nearly 3 years ago and have not changed the battery so no idea how old it is
