just noticed recent problems starting the treg. even after waiting for the glow plug warning light to go off. The first turn of the key elicits a feeble groan from the engine with hardly any revs showing. After turning the engine off and restarting second time the engine fires usually accompanied by a lot of smoke. The vehicle is going in this week to have investigation of a knocking noise on full lock at low speeds. I hope it isn't the stepper motor or transmission transfer gearbox. The transmission gearbox was replaced only a year ago under warranty. Will keep you all informed.
