I got a new transmission installed and now it failed

[soulflyer]

I got a new transmission at 96k km... see here https://www.audizine.com/forum/showt...ion-installed!

And 6000km later I got a transmission failure error in the dashboard, scanned it and then drove it to the dealer.
They scanned it too, confimerd that I can no longer drive the car and then gave me a loaner (brand new 2023 A4) which I have been driving for the last 3 weeks...
In the meantime the Regional Tech had a look at it and they are waiting to hear back from Audi in Germany.
The dealership is very supportive and keeps me informed on a regular base.

Here the scan result:

It is the DQ381...
tks for the link, love me some Deutsche Auto Parts! Their videos are always very entertaining..
I have a very good relationship with my dealership so I am patiently waiting for an update while I am racking up quite a few kms on this soon not so brand new anymore A4...

Update:

After a lengthy back and forth between Ottawa and Germany the TFM authorized yet another full transmission replacement... so they ordered another new one in Germany which will take its time to get here. That then would be the 3rd transmission in my car. They did not tell me what and why (yet). It is all covered under parts warranty.
Meanwhile I am on my second loaner... the first brand new 2023 A4 had a check engine light after about 1000kms and on my way to the dealership I blew a tire... not my best day... once I had the donut installed I finally made it to the dealer where they had an even newer A4 in a higher trim already waiting for me, another 2023 A4 S-line with only 65km on it. Looks like I will be driving that one for a while..
