Car has been overheating and cutting boost. No codes..
Yesterday while driving in 100+degree heat on the freeway, car develops horrible engine stumbling/vibration and flashing CEL..
Take her to dealer today..
Both cooling fans are faulty and need replacing and #6 coilpak is toast.
I will be trading this car in as soon as my new customized 2013 Lancer Evo X has been built and shipped here..
Saying good bye to Audi after 22 years..
