Fitment & Technical FAQ for Mercedes W168 (2001 - 2004) Steering System Part #A168-466-0501
On the W168 A-Class, a loud whining noise or "heavy" steering is almost always caused by an internal motor failure in the A1684660501 electric-hydraulic pump. These units often suffer from "cavitation" (air bubbles) or worn motor brushes. Replacing the pump with our tested unit restores the 71-73 bar hydraulic pressure required for effortless steering.
Yes. Part number A1684660501 (and its predecessors like 1684660301) is the standard OEM unit for the entire W168 A-Class range (1997-2004) and the Mercedes Vaneo. It is a direct "plug-and-play" replacement for these Australian-delivered models.
After installation, fill the reservoir with MB-approved fluid. With the engine running (or pump powered), turn the steering wheel lock-to-lock 5–10 times. This "self-bleeds" the system. If the whining persists, it usually indicates air is still trapped in the lines or a leak in the return hose.
