Last time i had the car put on a star machine it brought up a fault code for cylinder1 glow plug. I did have the usual glow plug light stay on till it got warm. Any way i replaced the glow plug at the weekend but i still have the same issue with the glow plug light coming back on till the engine gets a little warmer. Am I right in thinking that cylinder1 is to the front of the car on the drivers side. Can any tell me if i need to get the fault code removed or will it stop coming on over a number of starts?
