How to Change a VW TDI Fuel Filter 1.9 ALH diesel 

I love how these TDI's start right up, the starter turns over once and the car starts.

Being new to TDI's your video just saved me a ton of headache. Thanks!!!!

Just did this yesterday on my ALH. Get you some clamps/vicegrips and squeeze off the fuel lines, dont have to worry about priming or air bubbles. I usually run diesel purge directly from the can too. Also lol @ 9:07

You sounded just like me when I’m wrenching away. That’s why the kids have to stay in the house. 😂

Love it. I thought you might be UK due to your excellent language skills 👌. Good talk through. I'm about to do this. I was wondering where the priming was lol. Yours has done the same milage as mine

I always fill the new filter with Diesel Purge to give it a little cleaning with the filter change.

Thanks for the great video. Glad there were no kids around. Hahahaha.

Soon I will buy a golf tdi with this engine and your videos are very useful to me !!! Every how many kms should this filter be changed? Greetings from Argentina!

Lol, at the people busting on you for priming the filter with old fuel... it would be a pretty odd design for that fuel not to get run back through the filter anyway. And even if it does... these cars run long enough a little dirt in the fuel won't be what takes it off the road. I have to redo my fuel filter. I think it's been over 35k miles. She's at 379k.

What clearhose are you using from filter to pump? Mineare due for replacement would like to use clear. Thanks

Thanks for the vid

Leaving the outgoing hose off whilst filling the new filter is essential advice. I also filled that hose up with fuel before pushing it on to the spigot - started first time - runs so much better now!!

The names you called that clamp were classic!

Thank you, good video. And I use the same method you described to fill my fuel filter, use the vacuum pump to suck fuel into the filter.

Wrong.dont put the diesel from the old filter in the new filter. Dirty diesel you put in there

Thx for the video, i almost did the same mistake..😉😄

Prime that pls

Hi! What will happen if the yellow and black lines switch places on the diesel filter? (They are put correctly on the pump, my mechanic just switched their places on the filter). Please reply it’s kinda urgent..

Very nice good skill and useful tips i use to service my golf myself

Nozzle swap?

I hope you can answer this question I have, my 2006 tdi has a long crank start in warm conditions and I’m hoping that replacing my fuel filter will fix that issue, thanks

That's what I call those clips too.

What if you don’t fill the filter with diesel can you prime it and will it pull fuel? Or will you put air in the system?

I got 2 black rubbers instead like you got the black and blue, do those color rubbers make any difference?

Thanks for the video. I am gonna do this on my wife's jetta mk4 ALH. Should be same on mk4 BEW right?

Please don't put the dirty fuel out of the old filter into the new one not good practice

thanks for good work ,How can we tell if the valve called thermostatic tee is broken?

Greg love you but why say process like that. .. lol jk thanks you r a huge help.

Filtrul trebuia sa fie umplut cu diesel inainte de a-l monta, nu cand sunt yoate furtunele montate. Si nu era greu sa pui diesel curat, dintr-un flacon. Nu e mai bine sa introduci diesel prin teava de input?

I do a 50/50 mix

Ive done it twice and the first time I didn’t even think about. And i noticed air bubbles passing through that transparent hose, then second time Fuel filter change i did fill it up with fuel this time, and still see bubbles, did it messed it Up?

mine started right up. then died. then was a pita to start again but running smooth since.

Thanks for this video - very helpful. Doing this to my old Mk 4 Golf tomorrow - hasn't been changed for 9 years!

Doesn’t it needs have bleed the air first before start it? Like prime the fuel filter?
