Changing the fuel filter on Auris 2.0 d-4d

disconnect the flow meter

unclip the air box connector

unscrew the air intake hose clamp, 10mm wrench, and release it

undo the 2 metal clips on the air box cover and remove it by tilting it

remove the air filter

remove the air box, 3 screws to undo using the 10mm key

pinch the diesel hose clamp and slide it down

disconnect the hose

proceed in the same way for the other 3 hoses

Have a rag ready because some diesel will leak.

disconnect the electrical plug from the diesel filter

unscrew the 2 filter holder fixing nuts, 12mm wrench

remove the whole thing

compare filters (reference)

open the bleed screw under the filter

and empty the diesel into a container

we will take the diesel to the recycling center

I do not recommend reusing it because this diesel probably contains a lot of water.

undo the 2 clips that hold the connector

I use fine-nose pliers.

unscrew the clamping screw, 8mm key

remove the sheet metal

Disassemble the water presence detector using multi-grip pliers

Place the filter/filter holder assembly in a vise and release the filter using a strap wrench or similar tool

finish unscrewing by hand and remove the filter

remove the o-ring from the water presence sensor

and replace it

A new gasket is supplied with the filter.

Lubricate the gasket and screw the water presence sensor onto the new filter

Don't forget to tighten the bleed screw.

clean the scope on the filter holder

lubricate the new filter's O-ring

tighten the filter firmly by hand

present the sheet correctly: there are 2 arrows to align (I applied yellow marker on the filter holder mark for better visibility)

screw in the sheet metal flange screw, 8mm wrench

clip the connector onto the filter holder (2 clips)

position the filter/filter holder assembly

connect the hoses

I didn't think it was necessary to mark them. The diameters and orientation mean that you can't really make a mistake when reassembling.

put the collars back in place

connect the connectors

fill the filter by operating the priming pump

The filter is full when resistance is encountered while pumping.

screw the 2 nuts holding the filter holder, 12mm wrench

install and secure the air box, 3 screws, 10mm wrench

install the air filter

place the cover (be careful to position the 2 lugs at the bottom correctly) and clip it

Make sure the air intake hose is in place and tighten its retaining collar, 10mm wrench

clip the connector into its housing

reconnect the flow meter

start and make sure everything is working properly
