New generation turbo diesels

I just hope the metallurgy (big ends, rings, pistons, cylinder bores), and lubrication is being improved along with the fuel metering/induction systems. I can't help feeling that while huge outputs can be extracted (eg 200 kW from a chipped TD5) longevity may suffer. The other point is that increased power equates to increased ability to turn dollars/diesel fuel into CO2 ie power and torque don't come out of thin air

The big problem as I see it is that they are not servicable on the side of the road by the average owner, suffer from silly sensor/electrical problems and parts are horrifically expensive (ask any common rail diesel owner how much an injector costs). It would also appear that they aren't made to last any considerable period of time or do lots of k's. As mentioned basic things like injectors cost a bomb, cannot be serviced and can be ruined by crook fuel, not much help if you regularly refuel from drums and jerries or overhead tanks on a property or expect the vehicle to operate in adusty dirty environment. ( hang on didn't you buy a 4wd to take it away from suburbia?)
