Removing and installing bottom section of sump — AUDI

Removing and installing bottom section of sump on Audi: 14 steps, engines CPWA, CZCA, CZCB. What to remove, in what order, and what to check after.

Removing and refitting the lower, bolted-on section of the sump on engines CPWA, CZCA and CZCB on the SA platform code. The noise insulation comes off if fitted, the oil is drained, and the connector on oil level and temperature sender G266 is unplugged. The bolts are released in reverse order, 19 down to 1, then the pan is levered at the marked point and cut free of its sealant with a scraper, with the engine openings covered against dirt. Cleaning the faces is most of the work: sealant remover, a flat scraper on the upper half, a rotating plastic brush on the lower half, then degreasing. The timing that follows decides the seal: fit the pan within 5 minutes of laying the bead and wait about 30 minutes before oil goes back in.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
