053-103-663 Engine Oil Dipstick Funnel - VW Golf Jetta & Audi A4

Engine Oil Dipstick Funnel – 053-103-663

The 053-103-663 is a critical engine component that guides the oil dipstick into the crankcase. Over time, the original plastic funnel becomes brittle due to constant engine heat cycles, leading to cracking or breaking. A broken funnel can cause vacuum leaks, oil seepage, or allow contaminants to enter the engine. This replacement is manufactured from high-grade, heat-resistant plastic to restore a proper seal and ensure accurate oil level readings across a vast range of Audi and Volkswagen 4-cylinder engines.

This funnel is a direct replacement for the factory part and is designed for a simple installation over the metal dipstick tube. It is a common maintenance item for classic and modern water-cooled VW/Audi powerplants, including the 1.8L, 2.0L, and 16-Valve variations.

Installation & Maintenance Tips

• Clean the Tube: Before installing the new funnel, use a clean rag to wipe any oil or plastic residue from the metal guide tube to ensure a secure snap-fit.

• Avoid Debris: If the old funnel has shattered, use a vacuum or tweezers to ensure no plastic shards have fallen into the tube before inserting the dipstick.
