Alright, since this thread is still going I'm going to chime back in. Engine braking comes from compression, not from the engine being throttled. It takes energy to compress air to 1/21 its original volume, and with your foot off the accelerator the engine doesn't get any fuel to provide that energy. PEH, I'm surprised you didn't explain this in more detail when you posted earlier.

All three of my diesels have plenty of engine braking, probably even more than similarly sized gasoline engines. And as I posted earlier the revs drop like a stone in the 1980 240D. Although probably not dangerous, crash9's car is not acting as it should. crash9 - is the hood pad falling down? It could be interfering with movement of the stop lever.
