Do you have any specific advice? I have a small turbodiesel whose life I'd like to maximize.

Turbocharger - don't turn the engine off immediately after stopping, leave it running for a few seconds so the turbo has time to cool off. After starting, don't rev past 2k RPM until the engine oil had time to get into the turbine so it's not running dry(so not for a few minutes). DPF - don't drive in the city :P if you do, take the car out on the motorway every few weeks at least and maintain speed above 50mph so the car can burn out the soot in the filter. Double mass flywheel - well, it's designed to absorb the "shock" of attaching the clutch too early. So if you're driving a manual, be gentle with the clutch and your flywheel will serve you well. If you rev your engine and just release the clutch the flywheel will have to absorb a huge amount of force - it's designed to do that so it shouldn't be too harmful, but do it enough times and it will split and have to be replaced.

Drive it like you just stole it. Change the oil every now and then, and keep a clean air filter in it. If it is a TDI or Mercedes, expect to have to pull the intake plenum every 100k miles or so and clean the gunk out of it. Edit: PS Also, do the timing belt maintenance if/when applicable PPS: R&R the glow plugs every 50k or so. You may even be able to re-install the old ones (test them first). This is mainly to prevent them from becoming seized to the head, necessitating an expensive repair.

gambiting has the right advice. I would just add, that: - the few seconds to cool down the turbo is about 30 to 60. Depending on the ride you just had. Just listen half a song more on your stereo ;) - DPF needs cleaning every cca 700 km (but really depends on multiple factors). You either have a control light, that will let you know, or you notice a sudden fall in distance-to-empty, because that fuel is being used to burn out the filter ;) Basically, even if something breaks there, it is still possible to repair it. However, it can be expensive (1000+ EUR for DPF or turbo, again, depends on the car).
