Follow these steps carefully
The 2009-2011 A6 (C6) came with the 3.2L FSI (2009) or 3.0T V6 (2010-2011). This guide covers the 3.0T: 6.6 quarts (6.2L) of 5W-40 meeting VW 502.00, cartridge filter up top. (3.2L FSI: 6.9 quarts — confirm in the manual.)
Audi's own process for the 3.0T is extraction through the dipstick tube: feed the extractor tube down to the pan bottom and pump the old oil out.
Audi's own process on the 3.0T is extraction through the dipstick tube, so I feed the extractor tube all the way to the pan bottom and pump it dry — chasing every last bit out matters here since there's no drain-plug flush.
Loosen the filter housing cap early so the housing drains back and air can vent. Keep the fill cap off to avoid a vacuum slowing the drain.
Loosen the housing cap on top of the engine and lift it out with the old cartridge. Pull the old element off, discard the old O-ring, and fit the new O-ring with a film of fresh oil. Press the new cartridge into the cap until it seats, then thread the cap back on and snug it — the plastic housing cracks if overtightened, a common and expensive mistake on the 3.0T, so use restraint. Compare the old and new cartridges side by side before installing — the same length and pleat count means you have the right part for the 3.0T.
The A6's cartridge housing is plastic and it cracks if you muscle it — I thread the cap on snug by hand and compare the old and new elements side by side first. A mismatched cartridge in a 3.0T starves the engine.
Pour in 6.6 quarts of 5W-40 through a funnel and reinstall the fill cap. Start the engine for a minute, switch it off, and check the oil level via the dipstick or MMI display — add small amounts to reach the full mark, never above. Inspect the housing and drain plug for leaks. Reset the service reminder and log the mileage and date. The 3.0T's large sump means the level moves slowly on the dipstick — wait a full two minutes after shutdown before judging the final level.
Six-point-six quarts of 5W-40 in the 3.0T, then I run it a minute, shut down, and wait two full minutes before checking — the oil needs time to drain back or the MMI reading lies to you. Add small amounts; never above full.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
