Hi,

I'm reading on the interweb that you must use VCDS to run the fuel pump(s) after replacing the fuel filter. Is having VCDS 100% necessary?

Is there a DIY trick of locking/unlocking and opening the door to replicate this without VCDS? Or simply just fill the new filter with diesel?

Also the websites I found saying you must do this VCDS procedure show a different fuel filter setup with 4 connections. Mine only has 2.

Asking cos I'm planning a DIY fuel filter change and don't have VCDS.
2010 engine, CFHD engine code.

thanks for any guidance smile

I have the 4 pipe version with a removable lid and i can confirm it does not need any special treatment after you have changed it. I just filled it with fuel as full as i could and it started straight up.

The problem is not so much whether it will start but the damage that can be caused to the high pressure fuel pump by pumping air and not diesel, the VCDS purge gets rid of all the bubbles.
