The V8 was so beautiful !!!!

Hello, dear community,
Be 20.12.03 I now raise an A8 4,2l with all imaginable frills and luxury.
But it's too soon.
But from the beginning, I had a V8 3.7l Exclusive and no problems except for a small rempelei with a Movano bus. Then in November 2002 my automatic transmission said goodbye. But I just didn't want to put so much coal in the aged gentlemen and got the 4.2 A8.
After four moons, I had a gearbox damage.
Ok now I must have bitten in the sour apple, But it's hard to believe, I'm still on the gearbox.
And this is not a joke, I have a top workshop!
At 280km/h, I lost something under the car, they don't know what to do.
Bolts remained over and were laid decoratively in the fender edges.
But then he ran first.First time six weeks ago a mistake, emergency run all lights from the selector lever indicator in the amaturary board.
No more switching, just four more. Switchboard.
"No problem, that's the multifunction switch on the gearbox," it said.
Okay, 250 euros poorer, I picked up my good piece.
After 11 km a jerk and the emergency run was back ??
So towed again and back to the workshop.
After many days of testing (three) it was fixed that the harness is damaged. The wire harness ????
Yes, that's wear and tear.
Who please changes the electrical installation in his house after 6 years because the cables are wearing?
The cable costs 1300,-Euro and the installation between 500,-u.700,- Euro.
However, a known expert says that happened during the conversion of the gearbox. My lawyer's back in work now, and my bolid's standing around.
Did I deserve this after my V8 accompanied me for 5 years, always got good food and never let me down?
I'm still driving Audi or ???
This is just an excerpt from the trouble with the car and the workshop. The car could do less for it.

First of all, thank you for the patience of those who have read to the end.

Always good ride and all more luck like me
