Detailed Description

URO 8D0422371K is a power steering reservoir designed for direct fitment on select Audi and Volkswagen models. It matches OE dimensions to help maintain factory routing and underhood clearance, while the heat- and oil-resistant plastic tank is built to handle engine heat and pump pulsation. This reservoir is a practical replacement when the original unit is cracked, leaking, or no longer sealing properly. This part cross-references VAICO V10-9730 for the same application.

What It Helps Fix

• Power steering fluid leaks from a cracked reservoir
• Low-fluid conditions that can lead to pump cavitation
• “Run dry” damage to the power steering pump
• Loss of proper fluid containment in the engine bay
• Fitment issues caused by an incorrect replacement reservoir

Installation Notes and Tips

Verify the reservoir shape, cap style, and OE part number before installation. Inspect the hoses, clamps, and surrounding power steering components for wear or leakage while replacing the reservoir.
