PART 2 Video - Weird engine noise

[Pisendar]

Hey guys.
On one cold night i decided to a take a little drive around since i barely drive my x5. So as soon as i turn on the car, i heard weird noise coming from the engine (either not engine) and few second later car almost like turned off by it self, but was able to keep up.

I am not sure if its normal or not, but something tells me its not. A made a little video so please watch and listen carefully to the engine sound

It starts on 2:25

YouTube - X5 noise
I dont want to sound too dummy but my guess - water pump, bad coil, spark plug and last one alternator is failing (m5james opinion,thanks)

I am planning to drive up to Big Bear lake , and not sure if it is a good idea

Thank you very much guys


------------UPDATE -----------
First suggestion i followed is to fill up the tank , so i did ,,, didnt feel the difference though. and this time you could hear the noise as soon as i turn on the car !!! PLEASE LISTEN carefully !!!!!

hi, to me it chokes in the moment when a secondary injection pump quits,
I heard a metal tapping noise in that moment,is that what you're concerned about?
Otherwise I hear just a squeaking and Vanos noise.Mine is 4.4i and Vanos sounds the same as yours,no squeaks here though.
The tapping noise like that I heard only once when my e36 318 was overheating.Stuck valve?

Range 37 miles .... sure that you really have enough fuel for all cylinders?
Or did I not see that right?

Good luck

No Engine light, no weird sounds to me... All I can hear is typical Vanos rattle.

The squeaking is from the belts.

I do not see a problem . it is very cold . you don`t run it much . the fuel system probably has more condensation in it than there is fuel which may explain the diesel like engine sound .
