Modern turbo diesels

G'day Marcus turbo life depends a lot on how you treat it, be kind and let them "run down" before shutting the engine off. Use a good brand of oil suitable for a turbo diesel and change it and the oil filter regularily. I have worked on turboed engines in trucks , tractors and earthmoving machinery and found that 9 times out of ten you will have to replace a turbo or two before an engine overhaul is needed. But please note most of these machines work a lot harder for a lot longer than your average 4wd. Hope this helps Brad

The only ones I have replaced on customers cars are the early 2.5 pajero turbo. At that stage Mitsubishi used to change them at the 80 000 km service in our area.
We had them done after market and never had a drama and the car was sold with 400 000 plus k's on it.

turbos should last as long as the motor does, and be rebuilt with the motor. However, bad warm downs and bad oil choice aswell as bad servicing and dropping them in water doesnt help their cause.
Sometimes looking for extra power can cause over boosting...that shoetens their life aswell...but as a rule of thumb, they are very simple things that should not wear out or need maintenance if oil is kept up to them....

My 2.5 Triton has done 240,000kms & turbo is untouched. Always had a timer set to 1 minute, sometimes more for arduous stuff. Mechanic says they should last life of motor so well see?
