Yes, you are right. The major noise was from the right shaft, but there was also a noise from the DMF based on what Audi center told me. I do not know the DMF manufacturer, but it is Audi original, thus I think it is Sachs. Even after having these repairs, the car still have some loose in power...

My car got finally new DMF installed by Audi center. Stationary vibration ended.

Yes, I got Bilstein B4's to each corner. The car is A4 B9 Avant 2.0TDI Stronic 2017. Suspension components are now Front: Bilstein B4 24-303828 (49mm clamping size) and Lesjöfors 4004323 Rear: Bilstein B4 24-262347 and Lesjöfors 4204311 Car is comfortable in lower speeds, but in higher speeds...

I am waiting for an approval for the repair from the used car warranty manager (non-Audi company where I bought the car a while ago). Parts and their repair / change are included to used car warranty coverage. Parts are coming from and the repair will be done at the local Audi center...

Latest update. My car got diagnosed today by Audi Center. DMF as well as front right side shaft's both inner and outer joints need to be replaced. DMF is keeping noise when opening right front window and driving close to wall. In normal drive the noise cannot be recognized in the cabin. They...

My car is getting worse and worse with the vibration issue. It is so bad I needed to get replacement car from used car dealer until it is repaired. Now I hear crackling noise always when driving and pressing throttle. I can hear it best when right front window is open and when driving close to...

About Koni SA prices, it would have cost me 507€ for all corners including 24% tax. Bilstein B4's are only 340€.

Update from me. It is very difficult or even impossible to get Koni Special Active's from factory as a consumer. They postpone their production window time after time. I have called several times directly to Koni factory here in Europe. They say they are waiting for certain number of orders to...

I went to workshop on last Tuesday as they emailed that Special Active's has arrived. It was nice surprise as they told me it takes 10 weeks. My car has 1BE suspension code thus should have 53mm clamping area size at front. Surprisingly when they took the front wheels off and measured the...

Here in Finland full set (four corners) is about 500€ based on indicative offer. I expect the final price will be little higher. As you can see from the pic, in some circumstances with the sport suspension the car body looks like diving, specially the rear end. Ski box and trunk are empty, so...

I have now driven the same model with comfort suspension. It wasn't either good compared to my previous BMW F31 with standard suspension. A week ago I went to a local suspension specialist workshop. Based on their and few other recommendations ordered standard springs and Koni Special Actives...

This research paper / Master thesis discusses about trańsmission technology vibrations https://pure.tue.nl/ws/files/46847781/584166-1.pdf Below is the most interesting part. I have noticed in my car when it is running just little over 800rpm idling, vibration starts, but some times when idling...

This vibration when idle at gear engaged is very interesting topic. Not just because I have it in my car, but because I have investigated number of scientific research papers related on dual-clutch transmission operating dynamics. Not yet found possible reason for Stronic vibration, but found...
