Dear All,
Just get this thread link from another topic, I'm searching for the reason of this sound what you can hear on the video, the car is an M2 N55 with DCT. Many of the M2's with dct having this sound, but also there is agroup where there is no sound, so it's confusing :/
The issue:
The sound comes ONLY in neutral, and loud only after cold start,
But its coming exactly 7 times in each minutes after 50 sec silence, 7 noise 50 sec silent and so on, if i change to gear 1 or R, the sounds stops immediatelly, and only comes again if i take it back to N, so its kind like expected/programmed. I have NO leaking on my dct, and there was no leaking before as well but ofc i don't know the oil level currently!
Question 1: Cold it be the jet pump?
Question 1: Is this unit electrical? Cause i check all the upper uploaded photos but i can't see any wiring/connection, but the name is still a pump, and pumps mostly electircal units i think!
Thanks for your help / comments
