The fuel filter on the Renault Captur diesel is hidden inside the driver's side front inner wheel arch. You need to remove the front half of the arch liner to access the filter housing, which is tucked behind the screenwash bottle.
This procedure is similar across many diesel Renault models of this era. The filter element sits inside a reusable housing — you replace only the internal filter and O-ring seals.
When You Need This Job
- Sluggish performance or hesitation under acceleration
- Diesel fuel filter change interval reached (typically 2 years or 40,000 miles)
- Hard starting

Tools You'll Need
Step-by-Step Guide
Remove the front inner wheel arch liner
Undo the T20 Torx at the bottom front of the liner and pop the push-fit clips along the edge. Pull the liner down and out to reveal the fuel filter housing tucked behind the screenwash bottle.
Remove the filter housing — three 10mm bolts
Two 10mm bolts are on the front of the housing. A third 10mm bolt is hidden behind the screenwash bottle. Remove all three and the cover comes off.
Disconnect the wiring plug and two fuel pipes
Unplug the connector on the top of the housing by pressing the tab and pulling. The two fuel pipes are colour-coded (green and white) — squeeze the coloured tabs and pull them up to release. Place a drip tray underneath.
Take the housing to the bench
Clamp the housing gently in a vice for stability. Undo the drain plug at the bottom and let the fuel drain into a container.
Remove the five T30 Torx bolts on the lid
Five T30 Torx bolts hold the lid onto the housing. Remove all five. The retaining ring will drop down but stays captured in the vice.
Prise the lid off carefully
There is a large rubber O-ring holding the lid. Gently prise it off evenly. Remove and discard the old O-ring.
Remove the old filter element
The Bosch filter kit includes a special tool — a small plug that screws into the bottom of the old filter. Once screwed in it acts as a handle to pull the filter out. Do not use a screwdriver as it will bend the top lip and prevent sealing.
Fit the new filter and O-rings
Drop the new filter element in. The Bosch kit includes a new O-ring for the bottom — fit this onto the retaining plug. Fit the new lid O-ring. Replace the five T30 bolts and torque down evenly.
Fill with diesel and refit
Pour clean diesel in through the inlet pipe to prime the filter before reconnecting. Reconnect both colour-coded pipes and the wiring plug. Refit the housing with the three 10mm bolts. Refit the arch liner.
When reconnecting the fuel pipes note: green connects to the centre port, white to the outer port. Mixing them up will cause starting problems.
