2003 Vw Jetta 1.9L ALH that triggers P1248 Start of injection timing regulation. Seems like just setting the timing will fix it but after drives the timing goes out of spec again.

Very good logic about timing changing in either direction... I'll have to remember that!
None of us is as smart as ALL of us. Thanks for your help and supporting my channel.
Lots of time diagnosing the problem- and time is money. Hope your customer appreciates that!
I really appreciate your vids- (ordered auto valve body from you years ago). Donated to the vids.
Anyone who gets value out of these- consider that a small donation is a bargain compared to the value of the info.
Hey thanks for the donate!
good mixture of detail and useful diagnostics, I own a 99.5 ALH with 392 on the original engine, I bought the car new there in the Kansas City area, I live now in Central Oregon. I sure hope if I ever have major problems with that engine I'm somewhere in the midwest not too far away, I would really trust you to diagnose and resolve any problem, especially with the ALH engine I have seen you work on in many prior videos
thanks for the kind words.
Excellent video as always. I learn something new every time I watch one of your videos.
me too. I'd love to work with him. I've been working with TDI ALH and AHU engine for 7 years now.
@@Jesus-hx5vg Thanks!
Thanks!
I just noticed you donated. Thank you so much.
Just got this code on my sdi . Running wvo was thinking it was just cause ambient temp had dropped as had lumpy start but low performance and when flat out feels like Stavation. Gna check wiring and fuses for solenoid first but I'm now woundering if veg has made the piston stick hmmm
maybe....
@@CoolAirVw well it's not fuse or wiring . I advanced my timing anyway it's better but still there might have to try a fuel additive

Hi there i., having the same problem with timing , and de idle rpm is on 1200.
Thanks for your effort and time
Your welcome! I appreciate you watching and commenting.
Have a 1996 B4 Passat with cold starting issues lots of white smoke was told needs pump timed in.
could be.
I adjusted mine now ro exactly where you ended up here after mine was so advanced. It was way off the chart first. It this ok where you ended up, or must it be as close to the blue line as possible? Great video!
People say there are benefits to having it high and there are different benefits to having it low. in our shop or procedure is that its close to the blue.
What benefits for advanced timing and for retarded timing?
Is one for efficiency and the other for power?
I find that when the pumps sit around a while the QA can get sticky and cause the QA codes. Usually they will free up after a bit of running. That's probably what happened here.
QA and timing systems are different. That isn't what happened here. I agree though QA will sometimes stick like your saying.
Bonjour monsieur,
Tout mes respects a vous
Est ce possible de nous faire une vidéo montrant comment vérifier le bon calage ou la synchronisation avec l outil diagnostic vcds pour les moteur 1.6 ou 2.0 tdi
Ou au moins le lien de la vidéo au cas où vos aurai déja fais une vidéo en se sens
Et merci d'avance
Je peux essayer de faire ça. Avec le travail actuel et l'arriéré vidéo, cela prendrait des mois. Il peut y avoir d'autres chaînes qui ont déjà une vidéo pour cela.
Are there any symptoms of timing being out if we have no codes? The car ain’t running the way it used to and i’m suspecting the pump’s timing is indeed the issue..
Injection timing is very easy to check with VCDS so just check it or have it checked.
@@CoolAirVw ohkay sir! Will do it..Thankyou for the reply.
Hello good sir, apreciate the time and efort you put into making these videos.
I have the same error code on my alh even after distribution kit, injection pump replacement and yes the mecanic checked and adjust the timing on the replaced injection pump. Any thoughts?
Thank you in advance
Nice video!
thanks
I have Skoda Octavia 1.9 TDI ALH. I encountered P1248 after adjusting IQ using hammer mod. There are air bubbles in the fuel line from the filter to the pump. Rough idling, low power, diesel smell in the exhaust, engine vibration are observed. What could be the possible cause?
P1248 is for timing and wouldn't be affected by IQ adjust. Some air bubbles are normal. I don't know what is wrong. Use the techniques in the video.
@@CoolAirVw Thank you so much for the advice. I removed the fuse 29 and I could find the change in engine sound. I will adjust the timing using vcds and also make IQ adjustment using adaptation. I would revert if it doesn't solve the issue.
@@balajiparthasarathy9490 Thanks for watching and commenting on my channel
What would cause the timing to not be stable. Mine at temp jumps between 50 to 75. All the videos I have seen they are all steady. 200k+ Miles. Thinking about just installing the 11mm pump as I figured mine is pretty worn.
They jump around a bit. Vagcom even offers a "cloud" feature IIRC to show how much. If your not having a code I'm not sure if you have a huge problem. I have another timing related video you might want to watch. not sure if it directly applies to your "problem" or not. ua-cam.com/video/Q5AZ2iXbg4k/v-deo.html
@@CoolAirVw ya no codes. Just my first Volkswagen diesel. Got it for 250 bucks because of kid lowered it and hit his oil pan so I rebuilt the engine over winter and was kind of surprised how gutless it was. Slight blow by over 200,000 miles I installed a clacker pump as a lift pump and that helped immensely was just curious if I messed up the timing. Videos always show the timing is steady and mind bounces thanks for the reply appreciate the help. Can you believe that I work on turbine diesel engines and this little thing still gets me 😂
@@randomstuffwithporgy3879 cool!
After changing timing belt kit i got Fault code: P0252]
Injection Pump Fuel Metering
Control
"A" Range/Performance
(Cam/Rotor/Injector)
Any solution ?
did you adjust injection timing using vagcom on the graph similar to what was done in this video?
@@CoolAirVw I didn’t have it.but car is running totally fine no rough idling no smoke perfect cold start
@@arpan711 check injection timing with vagcom
Wonder what would cause the piston to chunk like that.
Things fail eventually. time mileage heat wear and tear.
Are their kits to rebuilt those pumps??
There are gasket sets that are easily available, but parts for repairs would have to be ordered through a Bosch authorized service center. The quantity adjuster is a expensive part.
Can I get your email? I have a question about mine if you wld take the time please thanks
