Sorry for my complete ignorance but ive just bought an Astra Club MK4 02 and somebody has previously fitted an SXI dash to it, for some reason the speedo will work to a certain extent but not enough. Sometimes all the gauges will stop working and my petrol light will come on despite having fuel in the tank. Also there isn't a mileage display on the LCD screen which really has me puzzled.
Again sorry for my ignorance as I am a complete novice.
Thanks in advance
