Hello, I’m having a problem with my 2006 e90 330d.
It’s on 205k miles, and after the turbo blew and running away on itself, the turbo was replaced and was smokey ever since. So the decision was made to fully rebuild the engine.
It got new rings, valve seals, head gasket, bearings the lot.
It always started first time until the rebuild.
So now it’s rebuilt I can’t get to the bottom of an issue. If I leave it overnight, the first start takes a couple seconds, then dies instantly. Start it agin straight after that and it will run rough for about 10 seconds then run absolutely perfect. Full power, no running issues at all.
My plan is to sell so in reality I don’t really want to spend a fortune on it and start throwing parts at it.
Any thoughts, or ideas to test would be a great help. Thanks
I would start with reading codes with a BMW capable scanner, as I'm sure there may be some, and then log fuel rail pressure and the in tank pump fuel pressure, as a start.
Timing has to be spot on, and compression tests should be performed as well.

There’s no codes, at first there were glow plug codes, but fixed that. Now none.
I’ll check the fuel pressure with a snap on scanner.
And the timing was spot on as that’s been double checked issuing timing tools.
Thanks for your reply
If you still have the old glow plugs, you could swap them in just to see if the issue stops, or changes in intensity. That could hint at the fact that the new ones, while not triggering fault codes, are problematic. Especially if they're not OEM plugs.

In non-freezing temperatures the glow plugs on any modern direct injection diesel have little to nothing to do with starting or running. The car will start without them even in freezing temps, but just harder.

The problem was there before fixing the glow plugs, and after fixing the issue was still the same.
So the glow plugs seem to not be related to the issue.
