Terrible sound from the engine

P38, 2001 model with BMW diesel, 150 000 km:
A few days ago with a lukewarm engine I tried to start the engine, but by mistake pulled back the ignition key just when the starter motor engaged.

I then did a proper starting sequence and the engine started, but with a rattling sound as if all the valves were ticking at the same time. Being not far from home I drove slowly home with a rattling sound. Downhill the rattle was almost gone, but as soon as there was a flat, rattle as an old Mercedes 180.

Coming home I could smell unburned diesel fumes behind the car.Next day when trying to start, she does not want to start, but after a long time slowly with the assistance from the starter motor she start to turn around, a steady valve rattle as the day before, perhaps worse since she was cold. Strong smell of unburned diesel fumes and bellowing blackish smoke.

Have read the attached info with a Nanocom (at idle with a rather cold engine as I can not let her run for a long time with the rattle and smoke) , can loock as if the Timing Modulation is way off. Can this be due to the timing chain jumping a tooth? or can this be due to the no. 4 injector being faulty?

Also the value for the SWG setpoint seems to be too high.

Any ideas to where to attack appreciated.

Possibly yes. You need to investigate before you maybe lose a chain and bend some valves if you have not already done that. If a tooth has been jumped it will more than likely be the crank sprocket. Big job to replace chains and sprockets. Crank sprockets are difficult to get hold of.
