Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 49 · 850 CCA battery, OE oil filter 021115562A. Note the factory engine air filter, fuel filter, serpentine belt and cabin air filter are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2001 Audi A8/S8 lead in one area — the tires, 4 of 18 reports (22%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the tires, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the tires pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
