I have a problem: my fat guy's head seal gave up at 185,000. That's nothing unusual. My problem: some other muckens. The engine is completely decomposed.... I had the error read "adaptive mixture alteration to lean". In addition, the engine is jogging in the under-touring range (3.+4.speed) as well as in a switchcar that is about to dribble off. (1,250 - 2,000 rpm). When it stands, the vibrations are also very clear in the interior. A glass of water on the dashboard gives you a good wave!
But I will not leave the car, because I am attached to it, therefore my question: does one of you know?
a) where this stupid undecided motor run can come from
(LMM???) - a V8 can't run like this!!!
b) is there a company that completely overhauls Audi engines (4.2) against invoice with warranty?
Thank you in advance for your help!!!!
