The turbo failure is normally cause by excessive carbon build up in the engine caused by no 3 injector seal leaking carbon into the engine. This inturn gums up the oil feeds which causes the turbo failure.

Not sure whether problem is redressed in the 2009-10 models.

regular oil changes would help, but a periodic removal of the cam cover to inspect the injector seals is the only answer.

excellent advice.

not only do the fine oil ways inside the turbo foul-up with sludge (or worse) but the hydraulic tappets do too. the Ford oil change interval seems more about making the car appear cheaper to maintain than prudent maintenance. by nature diesels taint the oil with carbon far more than petrols do. 'oil is cheap, engines are expensive' as someone once said.

just passed 235,000 miles with mine doing around 8-9000 miles in recent years. I change the oil every 6 months and the filter every 12 months. if the mileage goes back up the oil changes do to.

for anyone reading this threat, changing the oil and filter on these engines is easy. the oil doesn't need to be an expensive brand, just make sure its full synthetic and meets the right spec. you can buy 20 litre drums to get the cost right down.
