Well, according to this my engine is stuffed. With a 320 Cdi not sure I have actually gone over 4000rpm that many times. Glad he says "4500 through the gears" as that would be about 150mph in 5th!

What's the best way to run-in a diesel?

For the first 1,000 miles do not exceed 3,000rpm, but make sure you reach 3,000rpm regularly. For the next 1,000 miles (to 2,000 miles) do not exceed 3,500rpm, but make sure you reach 3,500rpm regularly. For the next 1,000 miles (to 3,000 miles) do not exceed 4,000rpm, but make sure you reach 4,000rpm regularly. For the next 1,000 miles (to 4,000 miles) do not exceed 4,500rpm, but make sure you reach 4,500rpm at least a couple of times a week. After that, no limit, but make sure you continue to hit 4,500rpm through the gears several times a week. The benefit of this is it helps to self clean the injectors, it blows any accumulated soot out of the exhaust system and it helps to free off the piston rings, making the engine more efficient and less likely to use engine oil.
 
Basically don't rev the engine right up to the governor but make sure you give it some full throttle loading, especially up hills.
If you don't load the engine it won't properly seat the rings and will glaze the bores. You will then end up with a slow oil consuming motor.
