Common Rail TDI – Fuel Filter Replacement and Prime/Bleed
Procedure
October 10, 2014: Update to Information.
When replacing fuel system components on the Common Rail TDI engine (including the fuel filter), the fuel
system must be primed. The procedure should be available on most models through Guided Functions. If
not shown, then access through Control Module OBD. Run “Basic Settings block 35” three times in a row.
This activates the electric fuel pumps and bleeds the fuel system. Once the system has been bled, it will
be necessary to start the engine and idle for a minimum of 5 minutes before depressing the gas pedal.
