Hi bunny
Did you fit the kit yourself?
No, it was fitted when the car was at the factory for Centa & chassis 'upgrades'. I don't think it's a DIY job because the ECU also needs to be re-programmed (it turns on the fan at low speeds and when stationary).
I guess it should be possible to just install the cowl & fan with a manual switch but I don't know anyone who's done this.
