JTD starting problem
I have a problem with my JTD, sometimes it doesn't want to start. The starter motor is running ok but the engine won't catch. It might promise once in 4-5 tries and until last week it had always eventually started after perhaps 10-15 tries. When it did, it smoked badly immediately after start to stop smoking after a couple of seconds. Last week it refused to start altogether, had to tow it to the dealer. They could not find anything wrong with it. No faultcodes. Started after a nights rest in the workshop. The weather doesn't seems to be the cause of this since it has occured in the range between -5 to +28 C. It only happens when the engine is cold.
Any clues where to look? Potentiometer/throttlebody or something else?
