Audi A8 2000 3.0 diesel fuel bypass valve

[darius89]

Hi, today I scanned Audi A8 2000 3.0 diesel engine, and got error 19472 fuel bypass valve open circuit or short to ground.
Car didnt starts.
Where located that valve ?

Fuel Bypass valve N312

The Valve is integrated in the bypass of the electric pre supply pomp.
It opens for 40 seconds when the ignition is turned ON (terminal 15) and closes during the started cycle (terminal 50)

Check the wires and connections. And the valve 312. Its near the supply pomp.
