Hi there it takes 10 minitues to remove the lower dash area where the steering wheel is. Bottom panel, romove all screws visible then pull bottom panel off. Remove more screws and remove more panels. Get a torch and look to see if there is a rubber gromit in place blocking a hole. Open the bonet and look right into the corner. If the gromit is not there you will be able to see inside your car. Get some silicone to block this hole.
