I was wondering does anybody know how to turn off canbus system, is it possible to pull some fuse out or anything like this. Thank you

In short, no. CANBus is the connection protocol between each ECU (Theres more than you think) in the vehicle. If you are attempting to fit HID's to the car, you'd be better trying the capacitor trick or buying CANBUS compatible HID's.

The canbus is what runs the car. No canbus = no car

If fitting HIDs then don't. It won't cause any issues with your car and won't blind and dazzle oncoming motorists

Don't worry I won't fit HIDs...I was wondering that for fitting LED lights and to remove the dashboard error but thanks anyway people

Ah right, so it's not the canbus you want to shut down just the bulb failure warning. Could so the resistor packs but they tend to get very warm.
