Removing and installing fuel filter, engine code CVCA, DEKA — VW

🧭 Before you start

With the ignition off, unclip the fuel hoses from the coolant hose and washer filler neck, pull off the supply line and lay the lines aside. Undo the retaining bolts, raise the filter and unplug its lower connector. Remove the upper section by unscrewing its bolts in the specified sequence, then release the hose clips and detach the housing. Refit in reverse with the retainer under its bolt and the guide on its pin, then bleed the fuel system.

Fits: platform codes A32, A33

Don't miss

• Undo the upper-section bolts in the numbered sequence shown, not at random.
• Have rags ready; fuel escapes both when the upper section and the housing come off.
• Use hose clips to production standard on the fuel hose connections when refitting.
• Make sure the guide is properly seated on its pin before tightening the bolts.
• Bleed the fuel system after the job, before attempting to start the engine.
