Whining sound below 20mph
I\'ve been having a gradual increase in a whining sound (almost sounds like when one turns the steering wheel the full amount).
Can be described as a droning sound. Summary: Under 20mph Under 3k rpm Any gear Independent of turning wheel or not Independent of acceleration rate Getting progressively louder 2011 E90 DCT 4k miles Proper break in No mods Taking my car in but checking if this has been an issue. |

Tell the bitch to shut up!
Wasn't there any issue with the DCT cars? Something about the dealers changing the limited skip fluid with the wrong kind at the 1200mile service?

She was already in to change to the special fluid for the LSD. Helped that problem about 90%
This is a different sound - coming from front of car. Goes in thurs. I'll update when/if they diagnose. |

I have it too. Seems like it could be the A/C compressor possibly or a pulley. Something like that.

To be clear my issue is not the whining sound as described by audis5 in the below post

Here is a vid. iPhone so sound quality is not great. The whine/drone is between 1k and 2k RPM.
Again, it's much louder in person but perhaps someone can diagnose it from this clip. Also, the sound does get worse, this is about 50% of the max volume I've experienced. |

I would say definitely engine driven and not tranny.
Anyone know if you can knock a DCT into "N" while coasting? |

Thanks all.
Ironically it was the power steering fluid. Weird to me because: sound happened only when between 1k - 2k RPM w/ or w/o wheel turned So anything over 2k RPM and turning the sound would not appear, which I thought ruled out the power steering. All better now. |
