          I think he means the engine speed sensor on the passenger side of the engine,picks up off the flywheel

            we have different perspective for passenger side but left side of the car is left side of the car

              If the engine is not running, it will always show this fault code.
              This is normal operation, nothing is wrong. The fault code will clear once the engine is running.
              If your G28 was defect, your car would not run at all.

                Someone in Merthyr Tydfill has the same perspective as me though

                The sensor above the driveshaft reads the speed of the car not the engine speed

                  Exactly, and OP said it is G28 error that he sees with the car stationary.

                      As others have said, you will always get an "engine speed sensor" (G28) fault code if you pull the codes with the engine not running. For future reference, here is a link to some G28 engine speed and G4 crank position sensor info:
