It would be more prominent when cold, and would happen at idle revving in park as well as when driving....

I thought about the gearbox oil but wanted to clarify frist before stealer takes £230 for gearbox oil + filter.
It makes the noise whether is cold or hot but only when you floor it at any speed..1/2sec of wriiim or sort of
I never floored the pedal while in idle but did rev it up to 4k but no noise.
is barelly noticeble and passanger dont notice the noise..only when I ask did you hear it?? what?? that wriim..nooo I did not...once I floor it 2x they say oh yes..

Hmm... maybe its not the fluid then.

But defo don't take it to a stealer, or get a full flush at this stage.

You just want the level checked and topped up if necessary which any competent gearbox specialist should do for a fraction of that cost.

I preffer to watch what is getting done on my car or even better getting it done by myself however I have a driveway only not a ramp..Sometimes mechanics taking shortcuts when is a dirty job, like a droppoing the gearbox pan cleaning, changing the filter. When I say change the filter even is no need doing they might say we did that..few months later you go under the car and you realize the pan has never been taken off

Could it be a noise that can be described as an owl hoot? Is the car fairly high mileage? If so is likely known issue with the gearbox which requires replacement of the oil - ie full flush and replacement with a different grade of ATF, lifegaurd8 or some such. I believe the noise is the Torque converter clutch slipping. Is it particularly prevalent going in and out of third gear?

Hi..Thanks for the hint...yes it sound likel a owl kind of and 140k just passed..no matter what gear you at but is definitely not doing that at the 1st gear...when you in the motion and fully step on the gas it hoot...so
Shall i give a go with atf flush+filter? Keep the same atf oil(which one it is actually??or shall i get the lfg8 in?? I am bit worried that something will go wrong with the tranny once new oil is put in as stated on some forums.

A 'hoot' definitely sounds gearbox bad-fluidy.

Full flush could be good. The death of gearboxes after a flush is more associated with the 5 speed D2 boxes. The 6 speed D3 ones do seem generally far more reliable.

Just don't take it to Audi......

D3 Gearboxes are pretty robust but at 140k, an ATF change would be a good move even if you didn't have any issues.
Most important thing here is to make sure you don't give the job to someone that doesn't know what they are doing....
I'm not in the UK but I have used an Audi Dealer to carry out ATF + Filter changes 3 times on my old D3 over the years. They dropped the pan, replaced filter etc. but I think it cost about €500 everytime. The fluid is expensive.
