Hi All, I apologise if his has been discussed before, but I'll admit I'm a noob! I've recently bought a 52 plate 1.8 TDCI focus with 180K on the clock. New cambelt at 170K. Seemed to drive fine, but as soon as you engage the turbo it stutters and the glow plug lights starts flashing. When that happens I tend to loose all turbo control all together and today I lost power when overtaking a lorry (quite scarry!). I've taken it to a garge who chaged my fuel filter as they suggested the original was full of gunk. The car seemed ok for a few days without me using the turbo and driving sensibly, but the problem is still persisting. I've got a horrible feeling the turbo is on the way out and don't really fancy paying out as much for a new turbo as I paid for the car. I'm going to attempt a minor service on it with a flush to see if this helps, but any suggestions from the experts would be appreciated. Kind Regards, Alex.
