Replacement orange plastic oil dipstick funnel for select Volkswagen and Audi engines. Replaces brittle or cracked factory tubes to ensure accurate oil checks.
$1.99
The 050 103 663 dipstick funnel serves as the orange plastic upper section of the oil dipstick tube for various engines. It provides a secure guide and mounting point for the dipstick. Consequently, it keeps the dipstick seated to prevent oil vapor from escaping. Furthermore, this component blocks debris from entering the crankcase.
Manufacturers use a heat-resistant plastic for this part to withstand high engine bay temperatures. Nevertheless, heat cycling eventually makes the original plastic brittle. This degradation often causes the factory tube to crack or break at its base.
A secure oil dipstick seal ensures both engine cleanliness and accurate maintenance. If the funnel cracks, the dipstick might not sit at the correct depth. Consequently, you may receive inaccurate oil level readings. A broken funnel also allows vacuum leaks in certain systems.
Since this funnel consists of plastic, it acts as a common wear item. Replacing a failing 050 103 663 dipstick funnel offers a cost-effective way to check oil reliably. Thus, a new funnel helps you keep the engine properly sealed.
Inspect the dipstick tube area if you notice these symptoms:
The dipstick feels loose or fails to click into place.
You see visible cracks in the orange plastic funnel.
The funnel section detaches from the lower metal tube.
Oil residue appears around the dipstick tube area.
You encounter inaccurate oil level readings.
Rough engine idle occurs due to minor vacuum leaks.
