How do you bleed a TDI engine?

To bleed a TDI engine's fuel system, start by ensuring the fuel tank has adequate fuel. Next, locate the fuel filter and loosen the bleed screw on top; then, use a hand pump or the ignition key to cycle the fuel pump until fuel flows from the bleed screw without air bubbles. Once you have a steady stream of fuel, tighten the bleed screw and start the engine. If it doesn't start immediately, repeat the process until the air is fully purged from the system.
