Walker 256-1086 Engine Oil Pressure Switch

Engine Oil Pressure Switch for OE-Style Monitoring

Walker 256-1086 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send the proper signal to the ECU or dash warning circuit when pressure drops below safe limits. It is a direct-fit solution for select Audi A3 and Volkswagen applications that require a 2.3-3.0 BAR switch response.

• OE replacement engine oil pressure switch
• Pressure threshold matched to factory specifications
• Thread size, terminal type, and electrical response designed for direct replacement
• Metal and plastic construction with oil-resistant, high-temperature materials
• 1 blade pin terminal, female connector, male terminal
• Brown finish with factory-style fitment

Detailed Product Overview

Walker Products 256-1086 is engineered for accurate oil pressure monitoring in the engine lubrication system. It threads into the factory mounting location, typically the engine block or oil filter housing, and connects to the existing wiring without modification. This part number is built for vehicles that rely on a 2.3-3.0 BAR oil pressure switch signal, including 2015-2016 Audi A3 and 2015 Volkswagen Beetle, Golf, Golf SportWagen, Jetta, and Passat.

For buyers searching for an Audi A3 oil pressure switch or Volkswagen oil pressure switch replacement, Walker 256-1086 provides the OE-style electrical response needed to trigger the warning light or control input when oil pressure falls outside the expected range. This part number 256-1086 is also a practical choice during drivability repairs, scheduled maintenance, or engine rebuild work where factory-style pressure monitoring is required.

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 or staying on intermittently
• False low-oil-pressure warnings from a worn switch
• No warning signal when actual oil pressure drops
• Faulty ECU input from an inconsistent pressure switch signal
• Oil pressure monitoring issues after engine service or repair

Installation Notes and Fitment

Compatible With 2015-2016 Audi A3, N/A, 2.3-3.0 BAR. Compatible With 2015 Volkswagen Beetle, N/A, 2.3-3.0 BAR. Compatible With 2015 Volkswagen Golf, N/A, 2.3-3.0 BAR.
