Fix your flickering or inaccurate fuel gauge with this genuine VDO fuel level sender for the Mercedes-Benz W123. These specialized "tube-style" sensors are critical for providing steady resistance signals to your instrument cluster. Every unit we sell is professionally extracted, degreased, and bench-tested to ensure the internal float moves freely across the entire resistance range.

Condition & Bench Testing
Unlike "pulled" units that may be seized by old fuel residue, this Genuine OEM sender undergoes a strict prep process:
Internal Cleaning: The protective tube is flushed to remove varnish and sediment.
Resistance Test: Ohms are verified at "Full," "Half," and "Empty" positions for gauge accuracy.
Float Integrity: The internal float is inspected to ensure it hasn't become fuel-logged or heavy.
Global Shipping Information
Secure Handling: These sensors are long and fragile. We ship in reinforced, impact-resistant tubes to prevent bending the internal resistance wires during transit.
