Oh, Audi

Illustration for article titled Oh, Audi

This is the fuel tank used in the C5 A6 Quattro and Allroad. Multiple level senders, an internal siphon system to transfer fuel between compartments, and a hole in the middle (for the rear differential). I am in equal parts horrified, in awe, and completely unsurprised.


This may explain the extreme nonlinearity of my Allroad’s fuel gauge... Between that and the 2.7T’s incredible thirst, anywhere below 1/2 means “fill the hell up NOW.”
