• Metal housing for durable engine-bay service
• Matches OE pressure threshold, thread size, terminal type, and electrical response
• High-temperature, oil-resistant construction
• Direct replacement for factory oil pressure switch locations
• Supports dashboard warning light and ECU signal functions

Detailed Product Overview

Walker 256-1244 is engineered for accurate oil pressure monitoring in the lubrication system. When oil pressure falls below the calibrated limit, the switch sends the signal needed to activate the warning lamp or engine control input, helping the driver identify a loss of pressure before internal engine damage occurs. This part number is a practical choice for Audi 90, Audi 90 Quattro, and Audi Cabriolet owners who need a factory-style replacement with the correct electrical response and OE-style fit.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Oil warning light flickering during normal driving
• False low-oil-pressure warnings
• No warning light or signal when pressure is actually low
• Intermittent oil pressure switch electrical response
• Failed factory switch causing drivability or diagnostic concerns
