How to adjust the timing on a 1.9 VE TDI Injection Pump: On two different engines (ALH & AFN)

[@cactusapesgarage6580]

I'm terribly sorry for the delay before releasing this video, to anyone that might have been waiting for it!

[@howtofrank502]

I haven’t posted in a year man lol life is busy

[@TroopThrowback]

The single most useful and informative video on KZbin on this subject. Even if manipulation isn’t in your plan, understanding these concepts hasn’t been explained anywhere else on KZbin. Your explanation is so clear and thorough! More alh tech and tuning videos please!!!

[@josepolanco4867]

Best description about timing specs in relationship to the TDI graph! Thanks 👍

[@cactusapesgarage6580]

Thank you for the kind words!

[@donthatedonate]

This video is extremely helpful, I just used it as a guide to adjust the injection timing on my AFN. However, some EU market controllers like to request up to 3 degrees AFTER TDC under low load conditions, so make sure you take that into account when setting the timing and checking the N108 percent value, so the ECU can make that happen, otherwise the start of injection valve will keep hitting the side of the pump and go bad eventually. Thanks a lot anyways!

[@donthatedonate]

Also, make sure you counterhold on the delivery valve (its a 14 head) when cracking the fuel lines loose, because I didn't and for me, the delivery valve cracked loose instead of the fuel line itself and I had to replace its seal because it kept leaking after that.

[@TheeDude12]

How do I know if this is the case? I have a AFN engine where I just replaced the injection pump because the pump had problems adjusting timing. I got a "00550" code and the hole in the bottom where the N108 is installed, that slot was full of metal shavings.. Is that a result of something that you are mentioning, or is it just normal wear? The car has 380 000km.. I have just replaced the pump for like a week ago, and adjusted timing yesterday after this guide.. It was really hard to get the N108 to 4-6% because it changed a little when tightening all the bolts. I did settle at 2.8% and kept jumping to about 3-5% sometimes. It was either that or 10-15% Maybe I could have tried one more time, but I hope it was close enough..

[@davidparker9676]

Your video is the only one I have seen so far that talked about group 004 and the settings there taking duty cycle into consideration. Thank you for a very informative tutorial. I appreciate the effort you have put into making the video and the simple terms you use to make it easy to understand.

[@theronnienstedt8734]

Great video my friend! You should be a teacher if you're not already! That's what I needed exactly now I'm going to go adjust the timing thank you!

You rock man..thank you vey much🙂💪

[@ernstmiller7472]

I have an ALH engine and my early 98-99 Bentley manual specifies a Phase I torque for the old adjustment bolts. Then when the timing is set, they say tighten to Phase I torque then an additional 1/4 turn. You didn't mention tightening torque in the video and I don't have recent manual. Is this the same tightening scenario for the new reusable bolts or was it just for the early style bolts?

[@christianfreisinger34]

Thank you, nice and helpfull video.

[@desneturado]

Hello. thank you for such detailed description. Would you have a standard value for fuel quantity on group 001?

[@stefann5502]

for 1,9 tdi AVB engine code gives me error on group 000,how can I solve thanks

[@wildwillscustomsexhaustvid9677]

So I'm working on a 01 Jetta alh. But the head was took off without setting TDC, what should I do. I got the car with the engine already disassembled

[@valdrinmehmetaj]

Mine stands 2.8% a little bit above the green is that a problem?

[@ChefKolyo]

Hello grate video but i have one problem on group 4 i dont have injection control i have start of injection i search every group but i cant find it the car is VW GOLF MK3 WITH 1.9TDI 1Z ENGINE 1996

[@dominiqueeybers9186]

Thx great video

[@OfficialELTB]

Awesome video! I was led here after fitting a new fuel filter... I didn't prime it and introduced air into the system. I think I have finally removed all the air but I think I have damaged my injection pump in the process. When I check basic setting 004 my rpm is fine but the next box says 'early' and fluctuates between 'late' btdc is 1.3 and duty cycle is 94%. Any ideas? Thanks in advance

[@OfficialELTB]

UPDATE for anyone suffering similarly. IT WAS THE PUMP. Although it would run on tick-over there was lots of white smoke and it wouldn't rev smoothly or above 2-3krpm. I cracked each injector whilst running and only number one was receiving enough pressure (2, 3, and 4 only had a dribble) So salvaged pump on and we're good. Just need to time it now!

[@MrDelvey]

I have a ALH engine that lost the auxiliary belt. Managed to get it home and replaced the belt and tensioner. The timing belt is fine, but it will not start. Could this solve this?

[@cactusapesgarage6580]

Hm the auxiliary belt itself wouldn't affect the timing of the engine. I would be concerned for any wiring that may have been damaged from when the belt broke of. Did you manage to solve it?

[@MrDelvey]

@@cactusapesgarage6580 unfortunately not. The engine turns over, there is fuel at the injectors but firing up. Could shout with the wiring.

[@K2edg]

Is there a way to ajust the timing just using the 004 metering blocks?? i ask as i've just done a top end rebuild and am a little out of money....... i have the unregestered VCDS so i can see my 004 line duty is about 55% but i can't see the graph. I am tempted to turn the pump slightly anticlockwise and see if it helps or not.

[@dissoc888]

very good tutorial

[@dboss1380]

So am guessing there's no other way to set timing for the AhU and AFN without using VCDS??

[@Aintegrator]

Thanks, Man.

[@gusja2501]

have you heard of the Timing adjustment with an Hammer on the ALH? whats your oppinion on that

[@gunnar1911]

The "hammer mod" is to adjust the fuel quantity, not timing.

[@gusja2501]

@@gunnar1911 oh ok, thx

[@StasK-kj2bf]

can you tell,please.where i can get info about AFN engine vacuum system? owner before me made awesome experimental vacuum system that nothing works good.that is why i want to do like factory .

[@Murray-e4f]

Maybe im missing something in this video You show how to adjust duty cycle on the AFN but not timing, You show how to set timing on the ALH but not duty cycle I have a 03 1.9 TDI ALH with help of this video I found out how to adjust duty cycle in the VCDS Adaptation

[@woxiduswoxidus1167]

Great video but it is only partly useful. It was more helpful if video include injection pump tuning, when pump mounted on engine after injection pump repair, i.e. when you need adjust stroke values acc to the specification. And after that final tuning with VCDS. If you plan to make video about ho to make bosh VE inj pump fully mechanical, it shall be very interesting as well.

[@v2point0]

Does this also apply to the 2.5 5 cyl TDI? I assume yes as I see the engines listed in TDI graph.

[@rimmersbryggeri]

FRom what I have seen you need a dial guge for the 2.5 rail pump. Much trickier.

[@andy2a2m]

I hope i am not too late to ask questions. I don't understand the purpose of watching the graph if the fuel pump adjustment is based on the actual and specified start of inject and the duty cycle? I mean, can i just use group 004 to time it without reading the "TDI timing" graph? Thanks in advance

[@davidgray3621]

X2. I've just installed VCDS lite and found mine to be pretty much bang on specified vs actual.

[@WillThePlank]

I’ve managed to get the TDI timing graph on my ASV to be spot on but the cold start valve still floats around 2.8-3.2 with the IQ value floating between 3.2-3.4. Will it being at this value damage anything because the specified and actual timing is only 1.0 degree difference and the car runs incredibly well and his much better fuel economy than when it was retarded. Just worrying about damaging the injection pump or the cold start valve.

[@burdazza2711]

I gotta ask, what is that vw. ive never seen a tdi mounted like its driving the rear wheels

[@cactusapesgarage6580]

It's the older generation of passat (B5). They have a longitudinally mounted engine despite being either front wheel drive or awd.

Hello! What values ​​should the advance have on a 1.9 Tdi AXR PD WV Golf MK4 engine?

[@arpan711]

After changing timing belt kit i got Fault code: P0252] Injection Pump Fuel Metering Control "A" Range/Performance (Cam/Rotor/Injector)

[@rkan2]

What if I cannot retard the timing enough by moving the pump? Crack loose the pulley and and rotate it? I don't have access to TDI graph yet - but the duty cycle was 45 and when advancing the pump it went to ~70... BTDC changed by 0.5deg or more.

[@StasK-kj2bf]

super!!!

[@rkan2]

14:35 - Isn't this the opposite? "Pushing the pump towards the engine advances timing and moves it higher in the timing graph. Pulling the pump towards the radiator retards timing and moves it lower in the timing graph."

[@pawep8860]

what is the correct injection quantity (mg/str) for an AFN/AVG engine?

[@davidparker9676]

it is very low at idle. I don't have the exact numbers but it will be around 1.5

[@tonykollar6870]

I dont get why we need to adjust high presure pump ...when you changed timing belt ...isnt there a locking hole where we lock the high presure pump? Now if you try to lock crankshaft in tdc and camshaft then pin for high presure pump wont fit in....did I misunderstand something here?
