Audi A3 8V / Skoda Octavia III / Seat Leon 2012–2020 TDI Diesel Fuel Pump 5Q0919050AK

Product overview

This new diesel fuel pump is a replacement for MQB-platform Audi, Skoda and Seat models fitted with 1.6 TDI and 2.0 TDI engines. It is referenced to OE numbers 5Q0919050AK, 5Q0919050AD, 5Q0919050AP and 5Q0919050BB, and helps restore proper low-pressure fuel supply to the injection system.

In these diesel vehicles the in-tank pump feeds fuel to the high-pressure system, so a failing unit can result in difficult starting, loss of power, rough running or fault codes relating to low fuel pressure.

Technical specifications

Installation requirements

Professional installation is recommended. Disconnect the battery before starting and allow any residual pressure to dissipate. Access the pump through the service opening, taking care not to damage the fuel level sender. After installation, bleed or prime the diesel system as required by the manufacturer, then run the engine and inspect for leaks.
