Hi everyone, This goes on abit but I need to explain the circumstances first!!! I changed the oil two days ago. Yesterday I noticed rumbling when I exceeded 60mph. It thought that the tracking might have gone and was going to book the Copen in to be checked. Today after driving down the motorway (with constant rumbling and steering wheel vibration), I slowed down and stopped at some traffic lights. I noticed that the engine light had turned on and the engine fan was going. I stopped at a shop to buy something, when I started the car up again the engine light stayed on but the rumbling disappeared for a while then after about 5 mins started again. Has anybody got any ideas of what might be wrong with my Copen or what I can do to resolve the problem. Think I might finally have to use a garage and get a diagnosis, but there are no Daihatsu garages! What manufacturer would deal with Daihatsus in the UK?
