Surprice, Surprice when changing gear oil

Salü municipality,

after I finally wanted to start the change of Gertie oil (or. I have stumbled upon a questionable fact.

At first I was surprised that despite the bolted-down oil tray with a sieve, only 3 liters of ATF were collected. The tar-like plot was to be expected. But it didn't smell burned. Only after consumed ATF oil with slight abrasion. I don't think that's really worrying for mileage.

Now the oil cooler pipes and oil coolers are carefully blown through by even more than these 3 liters. ==References==


Now to the tragic fact:

After the underrun protection was removed (due to engine oil change) I took a closer look at the V8 from below.

I have discovered a "new" engine block, which I can hardly imagine. The whole block shines to the last angle!!! Just like new...

In order to be certain here, I would have to slip around on my knees at Audi and ask about the repair history. Should a new fuselage engine really have been installed here, then this throws a completely new light on the future of the A8.
IF it's a new block in the first place and it was made at Audi...

The way it looks, it's not just been cleaned. I can't imagine.
The master was also amazed and has the presumption that it is new.

However, questionable is now also where the oil on the exhaust has an origin. There's not a single leak there. On the left cat it is moist and it collects oil on the bell. No leaks were also detected on the gearbox itself.

It remains exciting

Danke Lukas,

ich gebe es mal so weiter. Allerdings haben wir alles abgesucht und nichts Auffälliges gefunden. Das Öl ist am Rohr vor dem Kat und "nur" auf einer Länge von wenigen cm.

Auf dem Hitzeblech ist nichts und der Simmering/Getriebeausgang sieht trocken aus. Dennoch muss das ja irgendwo herkommen.

Ist der besagte Simmerring hin, tropft es ja auf das Rohr.Erst durch den Fahrtwind landet es auf dem Kat.

Kurzes Feedback...

Nach knapp 3 Wochen ist der Ölwechsel endlich erledigt. Es wurden 6 Liter gewechselt und das Öl kam (so hat es sich zumindest dargestellt) von der harten Wannendichtung. Gefehlt haben ca 300 ml...

Schaltvorgänge sind weicher, aber der Ruck ist nicht ganz verschwunden. Er macht es noch ab und zu. Viellecht gibt sich das aber mit der Zeit. Der Glaube versetzt ja bekanntlich Berge.

Mit nun ca. 66% frischem Öl bin ich erst einmal beruhigt.
