About a week ago got a msg to tell me to top up coolant - so did so. Couple of days later same msg - looks like I have a very small leak. Two garages say they can see there is a leak, but no idea where and what. The second garage now want to drop the engine to take a look and they quoting lots of money to do so!! Reading the forums it looks like this might be the same problem that others are having with some plastic pipes? Can you tell me how you found out that it was actually the pipes that were split? Not been to main dealership yet as not got one very local to me, also warranty I have on second hand car is not covered at main dealership. Many thanks
