Step-by-Step Instructions
Follow these steps carefully
1
Work out which Vito generation you have
Park on level ground, ignition off. The Vito's 1996–2024 run spans three completely different vans, each with the cabin filter in a different place: 1996–2003 is the W638 (filter under the center console), 2003–2014 is the W639 (filter under the hood cowl), and 2014 onward is the W447 (filter in the passenger footwell behind the fuse box). Check your registration document or VIN plate before touching a single trim piece.
🔧 Mechanic's note — Tom Becker
Three vans, three filter locations — the VIN plate is your friend here. I've seen guys tear into the center console of a W639 because they never checked which van they had.
2
W638 (1996–2003): strip the lower center console
Back out the side fasteners of the lower center console with a 10mm socket (some are E10 Torx) on a ratchet, then remove the front fasteners with a Phillips screwdriver, and lift the console assembly out. Keep every fastener grouped.
3
W638 continued: move the pedal and open the housing
With the console out, remove the bar fastening the lower center console, then unscrew the accelerator pedal fastener and move the pedal aside — the filter housing sits behind it. Remove the housing cover and pull the old filter out, noting its airflow arrow direction.
4
W639 (2003–2014): go under the hood cowl instead
Lift the clip-in cowl cover segment with a flat-blade screwdriver, back out the filter holder's Torx T25 fasteners, and lift the old filter out.
5
W447 (2014 onward): move the passenger footwell fuse box aside
On the W447 the filter hides in the passenger footwell behind the fuse box. Do not unplug anything, just move it enough to expose the filter slot. Slide the old filter out, checking its airflow arrow as it comes.
🔧 Mechanic's note — Ray Delgado
I've found that ease that fuse box aside — don't unplug anything. One forgotten connector on a W447 and you're staring at a dashboard full of warning lights wondering what you broke.
6
Fit the new filter for your generation
Install the correct filter for your generation with its airflow arrow pointing the same way the old one's did. The three generations take different filters, so do not assume one size fits all Vitos. Then reverse your teardown.
7
Reassemble fully and test
Put every trim piece and fastener back. Start the van, run the blower through all speeds including recirculation, and confirm strong airflow with no rattles. On the W447, double-check the fuse-box panel is seated and locked so no warning lights appear.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Following the wrong generation's procedure — the three Vito generations share almost nothing in this job.
- • On the W638, trying to force the console out without first removing the bar and moving the accelerator pedal aside.
- • On the W447, unplugging fuse-box connectors instead of simply easing the box aside.
- • Buying one 'Vito' filter without checking the generation — W638, W639, and W447 filters are different.
