laguna II 1.9dci bad smoking

hi i have a 1.9dci laguna on an 04 plate it has just started smoking quite badly its a light blue colour smoke someone has said it could be the turbo the car has done 76k but has been regular serviced does anyone have any ideas thanx mike

I also have a Laguna 19 DCI, it has only done 53K and like yours has been fully serviced. The turbo has collapsed this week on mine and I have been quoted £1400 to have the repairs done. They have to fit a new turbo, intercooler and new hoses and I believe the oil feed pipes as there has been issues with these models. I have been told that there is no assistance with repairs from Renault which I feel is an absolute disgrace, there should have been a recall on these models as Renault are only too aware of the problem.
Needlse to say I will not be buying another Renault, nor will I be paying the dealers extorsionate rates to repair my car.
