So a month has passed, holiday time of the year - long waiting time, I have visited gearbox specialist - two of them and they do confirmed, that it is the gearbox fault and the sound is from there. Could be bearings which can be replaced, could be something else which is too expensive to repair - so gearbox swap looks like natural decision in this case. And hope it will not repeat.

I have taken my car to a local garage to check on suspension related issues: wheel bearings were tested on lifted car, one was changed, but without any results. They have also inspected exhaust pipe for any leaks/holes or connections, tyres were swaped front to rear. I see member Gojko, which also had this problem, but isn't clear what was solution for him in case he solved it. The sound on the OP clips and on my video looks very similar to me, so I'm wondering. Turbo pipe checking looks pretty complicated to do by myself since my car has water cooler intercooler and the air pipes are going behind the engine if I understand it correctly. The symptoms described in the first post looks the same. Speed dependent sound, no matter what gear is on, clutch removes the sound, very slow or minimal acceleration.

very sorry for bumping an old thread. by any chance maybe anyone has sorted this thing? I have exact the same problem and I do find it on different forums, but nowhere an answer what could it be. A4 B8.5 Ultra 2.0 TDI; pulsation is me slightly lifting off the foot from the pedal. Already have looked through the bearings, tyres, exhaust, timing belt was replaced recently due to mileage, but it was before that.
