The econ light could also be the sensor that sits on the air con rad at the front. Changed mine yesterday, took about ten minutes to do and have my air con back now. Part was £56 from the dealers. Easy job.
Wheels look great also. Would like a set for mine really. How is the ride now?
There's a horrible squeaking so i think maybe bit more serious, am going to get someone to investigate v soon. The ride of the car is a lot better with the 18" wheels. Which is something i thought was actually going to be worse - maybe it's the tires or something but it rides brilliantly especially on the motorway.
