My cars in at the garage to get some work done under warranty - the fuel gauge and temp gauge arent working and they have said it needs a new instrument panel. Now, is this a common occurence on A4s or is the garage playing it easy by just saying they will replace the panel anyway? - pretty sure the car needs a new coolant temp sensor and the management light is on aswell - now, if they replace the panel then my mileage is going to be different and im not really too keen on that! - what do you guys think? thanks.
