E39 Sudden death - help !?
Discussion
HELP, simply !
OK, so no problems starting or running for 12+ months, no known problems...then. Parked for 1 week at airport, went to start, immediate fire up, drove 200 miles home, 80-95 mph cruise, very comfortable and normal; stopped 10 miles from home, restarted after 10 minutes break, no problem, parked, bed.
Next day, started but with pre-heat warning (strange as at least 10 degrees outside), cut out, restarted, crawled 20 metres, cut out - will not start. Jumped in E46...
Then, after pondering, tried again few hours later.....and low fuel warning (50 miles to go only) - very puzzling, as should have been plenty, so got 4-5 litres into her from can, and tried again, now low fuel warning (only 30 miles to go...), then with foot to floor & firing with strong battery.....piles of smoke out the rear, splutter, splutter, low fuel warning (7 miles to go only), and big shudder, and dead.
Electrics re-set, all now in German.....and not a peep out of her, will not turnover even.
CLUES ??
Bloody horrible weekend !

Across every BMW I've owned, whenever the electrics have gone crazy, it's invariably been due to the battery being flat. I have had some very odd symptoms, lights flashing on/off, dire engine warnings, limp home mode (hence the poor running) etc.
I would take a voltage reading of the battery and go from there
Or, could it be a fuel pump issue? Don't know how the E39 determines "low fuel warning" but maybe poor pressure in the fuel feed .. fuel pump, fuel in tank, fuse etc.

Yeah but what would all the smoke signify?I would take a voltage reading of the battery and go from there

I'm assuming pre-heat warning means it's a diesel............so the following is unlikely to apply, but........my 2litre petrol floods very easily. If you fire up and switch off within 30 seconds, chances are it'll flood and be a bugger to restart. Usually requires a lot of churning over (30secs to 1 min) and it'll eventually fire with LOTs of smoke!
Also, I've had a an ignition barrel failure before (won't turn over at all) which was deemed a pretty unusual issue......although that wouldn't explain your previous symptoms.

OK, so trusted Independent arrived, and......engine would not turn at all, but.....oil dipstick was full almost to the top, and smelling it, he said "diesel is in the oil !" Literally, rather than 1-2 cm at the bottom of the dipstick, oil was all the way to the top.
Tow truck taken her to garage....will pop-in today afternoon to see what is planned to do.
Mechanic pointed at something to the right of the engine.
Wife's optimism....."It needed an oil change, that is good !"

I've seen this once before, the engine was so full of diesel that it worked its way up out the inlet ports and into the inlet manifold..
I think youl posibly find the high pressure fuel pump has popped its rear seal which basically allows fuel straight into the crank case ..
This could be costly 😒
