This 2007 Audi A8 L 4. 2 Quattro has 143,000 miles and has recently received significant maintenance including a new fuel filter, valve cover gaskets, front air struts, upper control arms, spark plugs, fuel control unit, and battery. However, it requires attention for the MMI control panel, rain sensor, steering pressure sensor, and sticking rear brakes, with a CEL indicating issues with the cam position sensor and intake manifold.
