I've also been getting a groaning noise at low speed turns lately, planning on asking about it at 40k service.

Groaning is the diff issue which is supposedly remedied by changing both the center and rear diff fluids... |

That is good news. Can you let us know what they ended up replacing? Thanks!

Your description of the sound as "a deep resonance" is exactly what we're getting with our Q8. That's a good descriiption.

Thought I'd fill you in on the eventual result. I say "eventual" since it took 3 service calls and over two weeks in the shop to get this fixed. The short version is Audi finally agreed to replace the center differential. That's fixed the problem, although we've only driven it a hundred miles so far.
The longer version is that at the first service Audi replaced the center diff fluid with a new version. The problem went away, but was back after a few hundred miles. They then installed some sort of spacer between the diff and wheel bearings that was supposed to limit noise transmission. In other words, mask the problem vs. fix. It did reduce the noise somewhat. When the car was in the third time, the shop foreman told me that Audi knew they had a problem and came up with a replacement fluid as a fix (the first service) but ours was apparently too damaged (18,000 miles) and after much back and forth with Audi, the decision was taken to replace the diff. The dealer was very good in handling all this. My service writer told me right up front what the problem was, but that Audi would want to slow walk this problem before doing the right thing (slow walk are my words, not his). After 18 months of ownership, experience with two dealers and a couple interactions with Audi NA, I've come away with the opinion that Audi NA doesn't let the dealers do their jobs. They micromanage from above and are slow to do the right thing. We love the basic Q8 for it's ride, handling and features but have been very frustrated with Audi's technical support on all the electronics and features, as well as the slow response to fixing the steering noise. This is our first Audi, and it's an open question as to whether or not we will keep it. |

I'm still getting popping, creaking on an incline or low-speed turn. I replaced the upper and lower bushing already, still the same.
Did anyone figure this out yet? |
could it be an issue with the cv joints/
