bought the car about 3 months ago and its taken a while for me to realise i have a couple of electrical problems 1 - only get 3.4v at rear 12v socket , with or without ignition on 2 - dash computer works fine except - distance travelled , average fuel consumption , average speed ( all the amounts with small antenna symbol) and 1 more which i think is link to #2, cant get cruise controll to work at all
