Introduction
Replacing the fuel filter on a Golf V plus 1.9 tdi 105 hp
-
-
The diesel filter is located under the cover connected by 4 black pipes located at the bottom left of the photo, just in front of the windshield washer filler cap.
-
-
-
Unscrew the bleed screw located in the middle of the cover then wipe off the diesel that comes out.
-
Then unscrew the 5 torx screws in stages, do 2 or 3 turns per screw then change screws and so on until completely unscrewed.
-
Also, so that the cover does not go up crookedly when unscrewing, start by unscrewing one screw then the 3rd, the 5th, the 2nd and finally the 4th, following the previous instruction, that is to say unscrewing in several times.
-
-
-
Once the cover is unscrewed, use a small flat screwdriver to lift it, then remove the used diesel filter from its location, just pull it upwards. Don't hesitate to force it a little, mine seemed stuck but by pulling hard it came off without any problem.
-
Empty the tank full of diesel using a hand pump (see 3rd photo) then insert the new filter and replace the two seals supplied with the filter (a small one made up of 4 small circles which is placed in the middle of the filter and a large one which is placed around and under the previously unscrewed cover.
-
You can screw the cover back on by repeating step 2 but in reverse.
-
Please note that you will not be able to start the car without having primed the diesel pump.
-
Proceed as follows: turn on the ignition (without starting of course), wait 10 seconds then turn off the ignition.
-
Repeat the operation 4 or 5 times and then you can start.

Hello Ali, this happened to me at home and I had to call the tow truck. It is in fact the fuel pump located at the tank that is HS. As soon as you empty the tank it can no longer fill up and your engine is no longer supplied with fuel. Apparently the mechanic who came to help me puts the fuel tank under pressure (compressed air at the filler cap, etc.) and the repriming is done. You can also try filling the tank with new diesel to the brim, even if it means overflowing when screwing the lid back on, hoping that the circuit will reprime.

Hello, I just took my 350,000 km Golf 5 for an oil change, they changed the diesel filter and the car won't restart, they say the pump is too old! I obviously don't want to spend money on such an old car but which was otherwise working very well until this incident today. Do you have a tip to give me to try to restart the car without changing the pump? This is not a Volkswagen dealership, it's a chain that does repairs for all brands but I don't think they're used to cars with so many km on the clock! If you could help me out, I would be very grateful, by adding this tip to your tutorial (which is also very well done) Kind regards,
no need for a pump to empty the diesel from the jar because the latter unclips from the support to be able to empty it

me personally on the golf plus I did not need to drain the diesel with a basin next to it placed on the engine without worries and to restart impeccable be really careful when screwing it back in to do it well as indicated to distribute the pressure also see if the seal that was already there is good if it is good no need to change it because the new one being thicker can cause a problem when tightening and cause a leak. exact also the filter can get stuck by suction and do not hesitate with a screwdriver by leaning on the edge of the filter tank to gently unjam it also check carefully no leaks over several days does not hurt either you can have a surprise after a day or two I would not say that it is that easy because if badly reassembled the pressure of the diesel is enormous and you find yourself stuck on the spot if you do not solve
