Hi all, After several years of running and maintaining C15s, I have now ' upgraded' to a 2001 1.9 d Multispace. Very comfy and modern feeling compared to what im used to. My only concern at the mo is a high idle speed and fuel consumption of around 27mpg. Got myself a Haynes but ive never had a vehicle with and ecu and am wary of fiddling with various sensors (everything has a sensor on it) in case it upsets the ecu. Im a reasonably competent amateur mechanic but im not at all au fait with computerised things. Ive never had a Haynes recommend taking car to a dealer for so many things. Essentially is there any basic precautions to take to avoid upsetting the cars brain. Thanks in advance from and automotive luddite.
