A used OEM Audi Engine Cap / Plug (04E103037) seals an unused port or opening on the 1.4L turbocharged and plug-in hybrid engines found in the A3 and A3 Sportback e-tron. Also referred to as an engine plug, this genuine component prevents debris and oil leaks from the sealed opening. Over time, the original cap can become brittle or lost, leading to contamination—replacing it with the factory part ensures a proper, snug fit.
