URO 1268300284 A/C Expansion Valve

A/C Expansion Valve for BMW, Mercedes-Benz, and Volkswagen

This URO A/C expansion valve is a direct replacement for select BMW, Mercedes-Benz, and Volkswagen applications. It is built to restore refrigerant metering and proper air conditioning performance during HVAC service, including BMW 318i, 325i, and M3 applications and Mercedes-Benz 300D, 300SD, and 560SEL models.

• OE-style valve dimensions for proper clearance and installation fit
• Built for high refrigerant pressure and wide A/C operating temperatures
• Replacement for failed expansion valves during system service
• High-quality materials for HVAC repair use
• URO part number 1268300284

Detailed Product Overview

The URO 1268300284 A/C expansion valve regulates refrigerant flow into the evaporator so the system can maintain correct cooling performance. When the original valve sticks, leaks, or meters refrigerant incorrectly, cabin temperatures can become inconsistent and system efficiency can drop. This replacement is manufactured to OE valve dimensions and is intended for select BMW 318i, 325i, 325is, 325iX, M3, and Mercedes-Benz 300SE, 420SEL, 560SEC, and related chassis applications, along with Volkswagen Vanagon coverage.

This part cross-references BMW 64 51 1 372 503 and URO-001106 for the same application. The part number 1268300284 is also used when searching for an OE-style A/C expansion valve for these vehicles.

Common Problems This Part Can Address

• Weak or uneven A/C vent temperatures
• Refrigerant flow restriction from a worn valve
• System performance loss after HVAC service
• Incorrect evaporator feed caused by a failing metering valve
• Fitment issues from a valve that does not match OE dimensions

Installation Notes

Install this expansion valve during A/C system service after recovering refrigerant and opening the HVAC circuit. Verify the valve orientation, line routing, and sealing surfaces before assembly. For Mercedes-Benz applications listed with “w/o Seals,” reuse or source the required seals separately as needed. Always evacuate and recharge the system to the vehicle specification after installation.

Quality Assurance

URO backs this part with a 24-month unlimited mileage warranty. It is manufactured for OE-style fitment and built from high-quality materials for use in demanding A/C operating conditions.
