Q: What key precautions should be taken when working on the fuel tank of a petrol/gasoline fuel system, given the fire risk for Petrol engines on 2015 Audi A3?
A: Observe precautions before working on the fuel system. Empty the tank, open the fuel filler flap, and un-hook the battery. Take off the back wheel and pick the fuel pump. Disconnect required lines, hold up the tank and lift it off. Unfit, re-fit, fit, and re-fit.
