I'd say its probably more a characteristic rather than an issue. Like I said it doesn't bother me at all as the engine in normal driving sounds it it should.
The reason I stated this was because I was reading this thread https://www.audizine.com/forum/show...tch-Valve-and-Mechanical-Distance-Calibration
One could argue that odb11 is also giving false information though. The same would happen with Ford's ETIS where it would state that there were updates for different modules that didn't actually apply to that model. Just ask yourself how does odb11 know this as it cannot connect to Audi's servers...
I am having the same issue. I am the second owner. My car has 150 000km. Audi confirmed that the vibrations belong to 2050813/7 TPI. If the brake is pressed just slightly vibrations are gone. Mine vibrations are quite strong and I think that it's getting worse. I have to shift to N while standing or use start/stop system. Sometimes right after cold start vibrations are quite severe that the whole car is shaking. I am really disappointed by Audi attitude. How can it be engine matter and in TPI there is written that engine change won't help. That is ridiculous. Many users solved it with idle RPM change through VCDS (it is possible up to 50 RPM). However this is not possible if you had ecu software upgraded.
My last option will be DMS change but I don't know if I willing to spend so much money just to try something. If nothing helps I will sell the car but I don't know if someone would buy it with this defect
I finally found a guy that downgraded my ECU software to 04L906026T, version 1981. It is the OEM version so you couldn't have any update. Idle adjustment appeared in the VCDS and it really does help. Vibrations are 90% gone but I am so sensitive that I can still feel that the engine is not running as it should but if there is no other help I can live with this.I share your frustration, I’m an electronic and electrical engineer working in a manufacturing plant with many far more complex machines than my car. I’ve been trying to figure it out for over a year to no avail.

After 2 days of testing I can't say it helped much. vibrations are still present mainly first 20-30 minutes after start. They have higher frequency but are still present.Agreed, it still noticeable when the engine is cold and it almost come and goes in pulses. I think our sensitivity is there because we’re looking for the fault. Most people don’t realise it until I point it out to them.

I would like to ask you how sure are you that your DMF had been changed? I am starting considering that I will change it but it is just too much money to waste if it won't help
I am afraid that ECU only takes 50 RPM. Anything above that value is converted back to 50 but I haven't tried it yet. Yes there is change in frequency.I agree with it not helping much. I was contemplating increasing the adjustment from 50 to 70 to see if that would help more.
Did you notice the pulsating change in frequency too by any chance?

I believe that you had it changed but the picture can be from different car I am just asking because I again red all the forums and found more users that changed DMF and it helped
I’ve just upped the idle RPM by 50 and it seems to have hidden the problem. However, need to wait for the car to cool down before confirming.
Also, does anyone know where I can read 2050813/7 in full, please?

Yes I got the exact same paper from Audi but the info there is not true. It is not just a slightly uneven engine run because the whole car is shaking and it is not true that it only does when the engine is cold. It was like that at the start but mine now vibrates even if the engine is warmed up. I really must drive on a highway for more than hour to stop the vibrations
