Be careful, use rag to catch the fuel, make sure the o ring sits right and check it doesn't leak afterwards. And if you want it to start within 10 mins of changing it, fill the housing with fresh fuel after you've put the new filter in.

The internet makes a “big issue” out of doing this job by suggesting it can only be done using a laptop & VAG software. I’ve done it without, and had no problems whatsoever. As deanshaw24 says, on the transverse engine make sure you pack an old towel or similar around the filter housing as you do not want to spill diesel into the area of the auxiliary belt and cam belt.

I would suggest hooking the filter canister top, by a bungie cord, to the wiper area to keep it out of the way. Carefully lift the old filter into a suitable container (if will be full of diesel). If required empty the canister with something like a turkey baster and wipe the interior clean. Insert new filter and carefully pour clean diesel fuel into the canister until the new filter is submerged – from memory about 1 inch from the top of the canister.

Replace the new o-ring into the specific gap in the canister lid – as said above it is very important for it to be lubricated. Personally, I found that diesel was not sufficient and ran the o-ring through my thumb and forefinger applying a thin film of petroleum jelly. Carefully press the lid onto the canister body so that the central supply pipe goes into the centre of the submerged filter. Important to ensure the lid is pressed down squarely and uniformly as it is easy to twist the o-ring and have a subsequent leak. Finish by gently tightening the lid screws in a star pattern – they do not need to be that tight as they are not providing the seal

Mine started first flick of the key.

I did not get a separate seal with mine it seems the filter housing top forms the seal some how I just got filter element in box min is a 2014 2.0 tdi
 
Apologies for my confusion - the 8v TDI fuel filter appears to have an integrated sealing ring standing proud above the filter body.

I was also told that the 8v tdi needed to be primed or can I avoid doing the primming.
 
Couple of vids on YouTube covering 2012 & newer VAG TDI fuel filter changes. I suspect priming via software is recommended (as it is also for earlier cars like mine) as it avoids any risk of contaminated or dirty diesel being poured into the fuel filter canister.

My plan was to empty canister of diesel and clean it and pour fresh clean diesel in before putting new filter in and putting top back on and then starting as I don't have vag com or VCDS to prime it.
 
Here's a video for what looks like the same filter as yours - I wouldn't advocate the mixture he is using, I'd suggest just simple, clean diesel from a clean container. There are several approaches to saturate the new filter. I put mine in a clean plastic container that was just slightly wider than the new filter and filled the container to the level of the filter - left it to soak whilst cleaning the filter holder. Then I quickly moved the new filter to the holder and just added a tiny top up - admittedly not being too fussy about it going into the middle hole. Everything was fine for me. Surprising how dirty the old filter was after 40k miles

Did you prime it or just start car what year is your car .
 
2010
I didn't prime - this process is to avoid having to do so.
Car started first turn of the key as usual
 
I've had some intermittent starting problems. Battery OK, so garage suggested replacing the fuel filter. Not sure if this was changed recently. How old does this filter look? 3 weeks? 3 months? 3 years??

It looks more like 50,000/5-years :chuncky:. Have a look at this vide0 (at around 1 min 50 secs) this looks like a filter that has enjoyed regular maintenance. I changed mine last autumn (which had done 4-years/40,000) and it was similar to yours.

Thanks, really helpful. Another garage claim to have changed this filter 3 weeks ago! They say this is expected discolouration after 3 weeks. In that time it has only had Texaco Supreme diesel flowing through it. The area in the engine bay beneath the filter was pristine and dry: as your video shows, it's difficult to change the filter without dripping a little fuel!
 
That does not look 3 weeks old :whistle2:. They have date of manufacture on them which give some indication (not absolute proof) of when they were inserted on the basis that garages do not usually keep stock for years. I can see the dating circle/arrows on yours - one should be the year and another the month.

Thanks. Looks like 8/14 to me. Also has a date stamp on the base 1.10.14. Would be consistent with when the car had its last service - Jan 2015.

Thanks again Retroman. Will be asking Audi HQ Customer Services for their opinion next . . . .
