I have a 2002 BMW 320d SE Tourer, E46 I think, now with 147,000 miles. I bought it in Nov 2007. After a £1500 bill to get it though its MoT my wife was driving the car and just 50 miles later she heard a bang and the car stopped. The engine would not restart, indeed it would not turn over. The car was taken to the original MoT garage where the crankshaft was found to have broken. A brown deposit was found around one of the injectors and the theory is that the injector had failed and had been pouring neat diesel into the cylinder causing some kind of "hydraulic lock". In the ensuing internal mayhem the dual mass flywheel and the clutch have been damaged and heavens knows what else. A new engine is being suggested. The car, even with a new engine, is not worth anything like the sums involved. Have you any views?
