Introduction
'''The steps are the same for a 1.6 TDI engine (>2010) as for a 1.4 TDI engine (<2010, 3 cylinders)
Please note, however, that the CAYB (1.6 tdi 90hp) and CAYC (1.6 tdi 105) engines require a diagnostic tool for step 7 '''
Parts
-
-
Open the hood with the crank located at the bottom left under the steering wheel
-
Locate the fuel filter
-
-
-
To remove the filter, you must start by disconnecting the 2 diesel hoses (inlet and outlet).
-
They are attached by small metal clips, which you will need to move using multi-grip pliers.
-
-
-
The hoses are no longer pinched, they are free... well, more or less... They haven't been touched for years, so they are a little stuck to the filter connections.
-
You must therefore pull the hoses in the axis, slowly but surely!
-
Be careful not to damage them, but you will see that you will have to force a little... You can possibly use a tool (thin flathead screwdriver?) to achieve your goals.
-
Be careful of the diesel that will leak when you go to unclog the hoses. Thin plastic gloves will protect your hands while giving you dexterity!
-
-
-
With the hoses removed, there remains a filter attachment in its housing.
-
It consists of 3 lugs that come back on top of the filter. You just have to push them outwards so that you hear a "click".
-
The filter is then free to be removed from the top.
-
-
-
The long-awaited moment: comparing the filters! Here they are, both next to each other, so you can compare height, diameters, inlets/outlets, etc.
-
The top view allows you to see that both filters have the 3 housings for the 3 lugs that will hold it in place in its housing.
-
Please note that some filters do not have these black plastic housings. When purchasing, I advise you to check the photo of the new filter you choose to ensure that this black plastic is on the top of the filter.
-
-
-
We proceed in reverse order, first the 3 lugs in their housing, with the characteristic "click" which assures us that le nouveau filtre à carburant is well in place.
-
Then we put the hoses back in place. First, insert them into the filter inlet/outlet, then bring back the clamps to seal the connections.
-
-
-
The new filter is in place, the hoses are securely engaged and secured by the metal clips which have returned to their place.
-
Now you need to fill the fuel filter.
-
To do this, turn on the ignition (without starting!!), then turn the key back to off. And do this a good twenty times! This operation activates the diesel pump, which will send the diesel into the filter.
-
Please note, this operation is valid for 1.4 tdi 80hp (BNV) and 1.6 tdi 75hp (CAYA) engines. For 1.6 tdi 90 and 105hp (CAYB and CAYC) engines, the fuel pump must be controlled by a diagnostic tool! -
It is best to provide a diesel pump even if you have a 75hp engine (CAYA), in case the manipulation does not work.
-
The best thing to do for this manipulation is to be 2: one to turn the ignition on and then off, the other to listen to see if the fluid is circulating in the hoses. This is easy to hear, no need to be an expert!
-
Once the action of switching the ignition on and off no longer causes anything to circulate (you can no longer hear much, possibly a slight build-up of pressure), this means that the filter is full, you can start!
-
Be careful, to hear the fluid circulating, you have to be next to the filter, in front of the steering wheel, you can't hear anything!

Hello, I just bought a Skoda Fabia II phase 2 scout 1.2 TDI FAP 12V 75CV for my son.
Could I know if the procedure for priming the diesel circuit is also suitable?
Thank you for your reply.

Good morning !
I don't have all the Skoda Fabia II engines that exist!! (2 is already not bad!)
So for the same question, I would give the same answer:
- have a small hand pump ready before touching anything
- do as indicated in the tutorial
- if this proves unsuccessful, use your hand pump to fill the new filter with the pump.
It is better to plan the hand pump before starting operations, because once the old filter is removed and if you have emptied it, you will not be able to restart to go and get material!
Good luck !
Hello, I can't answer the question precisely, but I did exactly the same thing on the diesel filter of a Fabia 1.4 TDI 80hp (engine code BNV). And the BNV and BNM engines seem very similar (it seems to me that only the power changes).
At worst, try to find some kind of small hand pump (with a suction bulb, they are easy to find) to fill the filter manually, if the first procedure proves unsuccessful... This is what is done on HDi engines, except that the suction bulb is already present under the bonnet!
So, what I would do in your place: try as in the tutorial. If it doesn't work, remove the filter and fill it with the pump, then put it back in place and try again...

Good morning,
I just changed the filter successfully, in fact, turning the key 10 times was enough to fill the filter. Thanks again for your advice and for the tutorial.
Hello, thank you for this very well done tutorial. I have a 1.4 TDI engine of 70 hp from 2007 (code BNM). To prime the diesel circuit, is the procedure which consists of switching on the ignition without starting also valid?
