96 PASSAT 1Z Tdi TIMING PROBLEM

[@cal82252]

The 5th gear trick is genius! Its great to watch a master mechanic at work.

[@CoolAirVw]

5th gear trick I learned from others on internet.

[@jarnovanrooij2484]

i replaced my pump got it running for about 3 seconds tomorrow i am gonna use this method this video was great to watch! very useful

[@fredflintstone8048]

Great video. Great diagnosis. Wow, what a PITA adjusting the fuel injection timing on those vehicles. Whatever you're charging the customer he should be very grateful. It sort of reminds me of the old mechanic's TV commercials where he states, 'you can pay me now, or you can pay me later'... Thanks for sharing. You're a man with a lot of knowledge of VWs.

[@CoolAirVw]

thanks for being a regular watcher of my channel.

[@dboss1380]

Due to the amount of testings you went through, after 1yr 6months, i finally got my 98 jetta 1.9tdi to run the way its suppose to. Recently changed the n75 valve, but somehow the boost temp sensor and needle lift sensor were both wrongly connected the same way. I swapped them around and went to test drive it, and can finally feel the difference driving it all because of your indept explanations.

[@CoolAirVw]

Ah, it feels so good when my videos help someone. Thanks so much.

[@Markb8608]

Richard appreciate your patience with customer in order to bring us this video. I appreciate your dedication to VW family. I have 2006 VWM Jetta MK5 5spd BRM with 400k trouble free miles. Normal maintenance is done of course to get me to this point. Dont forget everyone to donate to KansasCity . 10-20 bucks in return for being able to save thousands. Great Video Richard. Happy New Year

Your fuel system is totally different from an ALH diesel

[@davidparker9676]

I love these TDI videos, especially the old 1Z & AHU ones. Great catch with the swapped connectors, I am sure most techs would be ordering a #3 injector and scratching their head why it is still throwing the lift needle code. I'm considering buying a '96 Passat TDI wagon, such cool cars (except the whole door handle issue)

[@CoolAirVw]

Thanks! I would have broke out the scope if I wouldn't have found the swapped connectors.

[@SFlores1979]

Thank goodness for the ALH engine! Seems much simpler in them than this engine. Great work!

[@CoolAirVw]

[@kevinpalmer7452]

Very interesting I have to say that your very knowledgeable on those TDI’s brilliant how you found the fault with the mixed up connections. Used the TDI Checker on VCDS to set the pump timing on my 2006 LT 35 -2.5 TDI after replacing the belt I must have had 25 attempts before I got the graph right very frustrating but well worth the effort.

[@CoolAirVw]

I get lucky every now and then. I wish various makes wouldn't use matching connectors in areas that are close to each other.

[@davidparker9676]

The timing can be adjusted while the engine is running on these pumps. You only keep one bolt tight and watch the graph as you loosen the last bolt enough to change the timing to the desired setting.

[@CoolAirVw]

@@davidparker9676 good tip! Thanks!

[@Idk-fo4cp]

Yeah this is the way. Leave the easy bolt tight, loosen the rest. Start it, loosen easy bolt and adjust timing while the engine is running. Kind of frustrating watching someone do it the hard way

[@CoolAirVw]

@@Idk-fo4cp Excellent tip.

[@loumontcalm3500]

Thanks for the wheel trick! I'm surprised you took on "somebody else's" job.

[@CoolAirVw]

I like the customers that brought us this car. Great guys.

[@aware2action]

Diagnosis well done and explained. ❤👍👍. Not sure, if live adjustment with a pipe wrench on injection pump could have reduced the time to iterate, to get things right.

[@CoolAirVw]

Maybe!

[@danman9017]

wow you are the guy for vw .thanks great video

[@CoolAirVw]

thanks.

[@BertGraef]

Brings back distant memories of me timing my 79 Rabbit and 89 Golf. Was wondering if that 96 Passat has the same system where you check for TDC at no. 1 Piston, then do the cam setup with a flat bar and stick a round bolt into the pump drive pulley to get everything timed right and rock steady? Only thing different is before there were computers in these things , VW wanted you to set up a dial indicator on the injection pump , and of course you had to run out to buy the "special adapter tool" just for that purpose , then you had to loosen the pump bolts and rotate the pump. I never bothered with that, but just trial and error until the thing started and ran without smoking under heavy acceleration. And I would never have thought to check those misplaced wires. Ah.... probably owned by one of those farming kids who think they know everything about VW diesels just because they were brought up on John Deere tractors..

[@CoolAirVw]

yes it is the same where you lock the cam with a flat bar.

[@my85cats]

Great video! And the 5 th gear trick also!My question on my 1z Passat also is hard starting on cold days and takes the engine way to long to get to operating temperature. Coolant system has been serviced and new thermostat was installed.Also I was wondering if you can change the glow plug settings for what temperature they turn on and how long and that goes for the coolant glow plugs also? Thanks again!

[@CoolAirVw]

there is a glow plug duration change for ALH but I'm not sure if it works on your model or not. you can google "glow time duration" for vw tdi and probably find the procedure or email me your phone number and I'll txt you a pic of the procedure.

[@ryangilley2880]

Fantastic video good to learn about the old 1z that I have In my Passat I learned a lot thanks 🔥

[@Verschlimmbesserung]

Yep, I always turn the wheel when doing a timing job with one or two exceptions. Once I got lazy and used a spanner on my Audi afn engine pump to turn the engine and I suspect it was then and there that the pump's shaft developed a play.

[@CoolAirVw]

thanks for watching

[@jaietor5101]

to adjust the timing on advance always remember injection pump has to lean on the engine block.

[@CoolAirVw]

Lean! GOT IT!

[@gulfy09]

Those motors are the best TDI i had many

[@CoolAirVw]

cool.

[@chasingcapsaicin]

Nice work. Making me sad, got a project in and lost it due to bureaucratic mayhem. If I knew where it went I would have tried to get it back. Just about perfect wagon with a BEW, only thing stopping it was the clutch, took me too long getting it back together and getting the last parts. I just hope it did not get crushed with a fresh clutch in it. Took a ten foot breaker bar to get the axle hub nuts off. Found clutch bearing pushed through the pressure plate, after forcing it that way just to be able to start it. Was bound up like a fully ceased block, ran on first crank sounded like an old slot hit jackpot for a second but smooth as butter. Basically got stolen while recovering from the plague, no registration, on stands in apartment lot and flagged as a hazard. Only needed the axles, and wheels, bumper put back on. Cant stay mad forever.

[@CoolAirVw]

damn! i hate it when that happens.

[@chasingcapsaicin]

@@CoolAirVw It was all the barrings bouncing around in the bell housing, Bought it not turning, Got her home, and the clutch felt like a brick, so I just pushed till it broke through. started right then, ok new clutch and golden. Didn't do the paperwork,, life.. ill take it

[@mahirzuko]

Hi man, what software did you use to get the diagrams for the wiring like shown on 16:42 ? I really need to take a look into Diagram #2 for the fuel sensor wiring thank you

[@CoolAirVw]

This is a common question. Mechanics subscribe to services to get schematics and other repair info. Pro-demand, identifix and All-Data are the big ones.

[@mahirzuko]

​@@CoolAirVw Thank you, yeah I googled it latter with a screenshot and saw you were using alldata. I found a crack but did not download it since its a couple of hundred gb and I had not time for it. Read out from the basic vw diagram. The VW default diagrams are so unclear since there is only a list of sensors by abveritions and then you need to search everything out.

[@aygwm]

Doing the timing belt on these is easier than the ALH for sure

[@CoolAirVw]

yea

[@rossconverse9067]

Thanks for the informative video. I've had lots of diesels from different manufacturers over the years and all old cars that had no electronics. I'm spoiled by the simplicity and reliability. I know they pollute much more and aren't as good for fuel economy. Since I'm a retired mechanic I think I'll put my money and time into keeping my 300SD roadworthy. I still enjoy your videos though. Ross

[@CoolAirVw]

thanks for the "super thanks".

[@mr.t2585]

Wouldn't charge only 50 bcks for this job. ;) .. i adjusted timing on this old 1Z with engine running and vcds plugged in. Slightly loosen bolts and moved pump by tapping front or back to the engine. The job was done in 15 min.

[@CoolAirVw]

yeah, thats what I charge for ALH "timing adjust". but I charged diag fee for finding the swapped plugs. It was still a super cheap repair for this customer.

[@aygwm]

Doing this is even trickier when you’re supposed to have the car up to temp. Rotate the engine to line up the pulley, make an adjustment, then start and test again…. Oops it’s too cold now. Terrible! It’s actually easier to do the adjustment tilting the pump while it’s running…

[@CoolAirVw]

you know it!

[@TIIRONC5H]

I have this issue on my mk4 1998 tdi No acelerator response And Get rpm itself 10+and stuck there

[@FJ40Brian]

Does this procedure carry over to the AHU engines for timing?

[@CoolAirVw]

yes.

[@davidparker9676]

The 1Z is nearly identical to the AHU.

[@FJ40Brian]

Except the internals/pistons and rods are ALH and much better!

[@davidparker9676]

@@FJ40Brian The main differences I have heard of are the thicker 8mm valve stems and the Garrett turbo on the 1Z. Everything else I was under the impression was exactly the same as the AHU.

[@FJ40Brian]

No they made changes in the AHU engine and carried that over to the ALH.

[@dboss1380]

What exactly does the code 38 means in the second field?? I have the needle lift sensor connected correctly, but somehow it just doesnt accelerate the way it should. I tried in on a friend's vcds, and the second field reading wasnt constant. It was jumping around from 38 to about 110 and just keep on changing, but for the most part would stay at 38. And it was showimg the yellow lines on the graph. I advance and retard the pump and still no lines didnt appear. What could be the problem? Could it be a bad injector #3?

[@niviuk8335]

I had the same promlem days ago with the similar 1.9 AFN engine: no power under 1000rpm afer change of injector nozzles. I measured needle lift sensor resistance (98 Ohms) and put another one in that measured 80 Ohms. Worked fine. There may be different versions.

[@jasonfonnet9493]

Where are you located

[@CoolAirVw]

kansas city area. Go Cheifs !

[@guapo4518]

Why, did you not check for pump lift first? What your are doing is a shot in dark without first knowing what pump lift, whether retard or advanced.......????

[@CoolAirVw]

Pump lift? Can you explain what you mean by that? In english I think we would say "lift pump", and this car is not equipped. no Vw diesel came with a lift pump till 2004. If you mean something other than lift pump please explain.

[@guapo4518]

@@CoolAirVw English? What does language have to do with what you are FAILING to demonstrate? Moreover, again, read over what I am questioning about what seems at best "your vid simply is a text book example that illustrates your lack of understanding how to time an injection pump" Also, your turning the injection pump without loosing the tube rails........"that is a wanna be mechanic thing" for a Jokeswagen!

[@CoolAirVw]

@@guapo4518 Oh, the internet is so tiring. You didn't watch the whole video. If you had you would have seen at the end. At the end of the video we explain and loosen the tubes. With regards to Language, you told me to check a "pump lift"?? since your name is guapo an obvious spanish word and since you said, "pump lift" putting the adjective after the noun" which is how its done in spanish,. Whereas in English we put the adjective before the noun, I assumed you were a person who spoke spanish as their first language, is that not the case? Care to adddress why you asked about a lift pump when the car isn't equipped with one? I asked a simple question, " what did you mean by pump lift"? Of course you couldn't even answer that.

[@CoolAirVw]

And if your asking about the stroke of the plunger in the injection pump that would be how a earlier diesel (non-tdi) would be timed. For instance on a earlier Vw IDI diesel. So that again shows your incorrect. I do have a video on that but that is irrelevant on a tdi where you can check advance and retard on the scan tool.

[@niviuk8335]

@@CoolAirVw You can do injection timing on TDI tree ways: the traditional way with dial gauge in the back of the pump, electronically via VCDS or with an diesel stroboscope. I'm no professional and did it several times with the dial gauge on my 1.9 AFN engines (even when I had my own VCDS) - but with VCDS its way less time consuming.
