Detailed Product Overview

URO part number 1165450034 is an overload protection relay made for electrical system repair on select 1981 Mercedes-Benz vehicles. When the relay fails, affected circuits can lose normal operation; replacing it with this OE-style unit helps restore consistent electrical performance. The design follows the original fitment pattern for the 380SEL, 380SL, and 380SLC, making it a practical choice for owners and technicians working on Mercedes-Benz electrical, lighting, and body relay applications. Part number 1165450034 also cross-references URO-000797 for the same application.

What It Helps Fix

• Electrical circuits that stop functioning after relay failure
• Intermittent relay operation caused by worn internal components
• Heat-related relay breakdown in the engine bay or electrical panel
• Cold-weather condensation damage affecting relay performance
• Arcing or burnout inside the original overload protection relay

Installation Notes and Tips

Install this relay in the original overload protection relay location and verify the connector matches the OE layout before installation. Because it is a direct-fit reproduction, it is intended for plug-and-play replacement on the listed Mercedes-Benz applications. Confirm vehicle year and model before ordering, especially for 1981 Mercedes-Benz 380SEL, 380SL, and 380SLC applications. Part number 1165450034 should be matched to the existing relay number when servicing the electrical system.
