URO 06B133784R Secondary Air Injection Pump Hose

Secondary Air Injection Hose for Audi and Volkswagen

This URO secondary air injection pump hose restores the air path between the valve and air hose connection when the original hose splits or hardens. Built for confirmed applications on Audi A4, Audi A4 Quattro, and Volkswagen Passat models, part number 06B133784R supports proper secondary air injection system operation and hydrocarbon emissions control.

Detailed Product Overview

Part number 06B133784R is a secondary air injection pump hose made for valve-to-air hose routing in select Audi and Volkswagen applications. The curved AEM hose is sized at 16.5 mm inside diameter, 63 mm length, and 5.9 mm wall thickness to match the original routing and connection points. If the OE hose has cracked, softened, or split from heat and exposure to oil or fuel vapor, this replacement helps restore secondary air injection flow on Audi A4, Audi A4 Quattro, and Volkswagen Passat models.

This part cross-references URO-016285 for the same application.

Common Problems This Hose Can Address

• Cracked or split secondary air injection hose
• Loss of air flow between the valve and air hose connection
• Secondary air injection fault codes related to hose leakage
• Reduced emissions-system performance from damaged vacuum/air routing
• Heat-related deterioration of the original hose material

Installation Notes and Tips

Verify the hose routing before installation and confirm the valve-to-air hose connection matches the original layout. Clamps are required, so inspect the existing clamps and connection points for wear, corrosion, or damage before assembly. Because this hose is curved and application-specific, compare the inside diameter, length, and shape to the removed part before installation on Audi A4, Audi A4 Quattro, or Volkswagen Passat vehicles.

Quality Assurance

URO lists this hose with guaranteed fitment and a 24-month unlimited mileage warranty. The AEM construction is selected to resist cracking from engine heat and exposure to oil and fuel vapor, helping maintain reliable secondary air injection system function.
