seems to be a palm off somewhere along the line m8 surely warranty covers mechanical and electrical for the 1st 3 year, if its been serviced by them within the time /milage then im sure youve got a damn good case normally if its not been correctly serviced then a warranty company will void any claim under the rules, try phoning customer services and open a dispute with them get a case number and the reps name and start the ball rolling with that info all logged in there system
