300tdi poor starting

Still not got any further with this problem guys, to add to the trouble, the fun i had with the throttle position sensor are back with the CEL coming on around 1700 rpm and dropping in to limp home mode........ looks like i need another replacement TPS!!! the white smoke at start up is now hanging around for the first mile or so, so its getting much worse. Could this be a duff injector?

I know this is an old post but Google search brought me to it after suffering same problem. I did everything everyone else advised here and was beginning to think I'd have to buy the expensive potentiometer... Yesterday I tightened fuel line clamps that come from underneath bulkhead in engine bay and they did not appear loose but gave them a couple of turns and today Disco started immediately as before this problem occurred.. Hope others have the same luck...
