Hi i just lent a haynes manual it says they only need recoding when a new set of injectors are used in the vechile but if the originals are used it doesnt need coding up ive checked the diesel and its running through everywhere and theres plenty of diesel coming through the high presure pipes i do remember there was a bit of rubber that fell into the hole nearest to the gearbox but tried to get it out and couldnt see it and the hole doesnt look blocked etc but not sure if this would not make it run i rang a mechanic who said the injectors have lost there programme to the injectors and need recoding and said he will bring his laptop with the correct software to talk to the ecu etc
