Part 2 - Did The High Pressure Pump Fix The P2293?
Вставка
- Опубліковано 10 чер 2020
- In Part-1 the check engine light, P2293, was diagnosed and we found the high-pressure fuel pump follower had excessive wear leading to a low-pressure condition under load. Part-2 dives into the data and the results from the pump being changed. Enjoy!

Nice Mike, I really appreciate the thoroughness of logic of the approach.
Hey Alex, thanks for watching!
Mike Becker, Senior Instructor
Thank you Mike. Good job. Have a blessed and safe week to you and your family.
Hey Billy, thanks! You as well :)

After seeing the cam lobe in the first video you dove into the river..... you know Da Nile. We've ALL been in that river a time or two. : ) I guess this is why Eric O. calls them Eurotrash. Looking forward to the repair video. Hopefully the donor cam is good. Thanks for sharing your knowledge with us.
Hahah that's good Rick! I was in Da Nile!
Mike Becker, Senior Instructor
Tough break Mike. Looking forward to the cam swap.
It happens :) Thanks for watching!
Mike Becker, Senior Instructor
Oh man, sorry to hear that, Mike! Was worth a shot, at least.You'd think VW would make that pump drive cam a separate and replaceable piece! Of course not ... that would make life too easy for techs and customers ...
Well, I guess on the bright side, the engine will be performing at its peak with a new cam, and the proper fuel pressure to feed it. Plus, I'll enjoy the upcoming video. :)
Hahah Smitty, you win some and you lose some...this one was a definite loss! Oh well, it's been a nice learning experience for this engine.
Mike Becker, Senior Instructor
Great diag as always😁
Thanks Philly Dee, wish this one was an easy repair...but oh well!
Mike Becker, Senior Instructor
Awesome vid thanks
So you’re saying that the code is triggered by a deviation of pressure from requested to actual. Do you have any resource that shows what the requested values should be at a particular engine speed or load?
Wow..its so important video
Thank you so much for sharing.
Greatings from Indonesia :)
Hey Bang MDP, thanks for watching!
Mike Becker, Senior Instructor
As a European, I don't drive European cars for a reason.
That makes perfect sense! ;)
Mike Becker, Senior Instructor
Good thing you have a parts engine handy!
Hey David, fingers crossed the rest of the cam looks as clean as the pump drive lobe!
Mike Becker, Senior Instructor
Wouldn't it be sweet if the cam eccentric was a keyed replaceable piece!
Ohhh Russel, that would be amazing! Fixed in under an hour then. You're onto something there.
Mike Becker, Senior Instructor
Welcome to VW
guess what would break and egg out non-stop then lol
That would be to smart and simple, replaceable eccentric, they probably thought of that and rejected it in favor of replacing the whole cam, maybe a roller follower on the tappet? That sounds too smart also. 😨😲😝🙅
Wow! I came in late. By the looks of the replacement engine, there was a lack of maintenance by the previous owner. I sincerely hope the bottom end doesn't look like that!
Are you installing a new cam, pump, follower and whatever else is needed? Will the head need cam bearings? I hope the oil pressure's well within spec.
Now you've got me curious. My 2020 RAV4 (2.5L 4 cyl engine) has this pump. I am definitely going to keep up with the maintenance (especially oil and filter) with this vehicle! Oil is cheap. Engines are expensive!
Hey Mike, better late than never :) Yeh, I agree It was poorly maintained. The more I did into this car the less likely it is that i'm going to be hanging onto it after it's all fixed up.
Mike Becker, Senior Instructor
Hi Mike like the video hope everything works out for you on the old engine camshaft wise did you have chance to watch Frank Massey top ten test
Hey, thanks. I did check it out. He's got some great info!
Mike Becker, Senior Instructor
i'm suspecting since the sprocket is on behind there that the slot may be the head of a bolt holding that lobe on. it may be that easy. what bothers me more is the exhaust cam hitting the cover. is the head wiped out in the cam journals???
Hey Richard, yeh it bugs me too! I tried moving/shift it...doesn't seem to have play. I wonder if something got stuck in there at some point? I'll know more once the covers removed.
Mike Becker, Senior Instructor
Any videos or info on which lab scope and diagnostic equipment needed, without breaking a crazy budget? I basically need to troubleshoot one of my vehicles with rough idle and multiple engine codes, p0101, p0008, 00720, p0017, p0054. Or is everything getting into this over $1000-2000? Sorry to go off topic, but trying to find a way to get info on lab scope for shopping. I have a collector car and just can't seem to troubleshoot a rough idle, but pretty good when driving.
Hey Filazee, I know some people have had good luck with the Hantek brand scopes. Maybe take a look there. I'm pretty certain you can get them for under $1000.
Mike Becker, Senior Instructor
GoTech wow, im surprised actually to hear such an open-mind to the super budget stuff. I think thats awesome that you are there to support all who try to learn such a cool set of skills that I didnt even know about until watching your videos. Im the type of guy who would do all the mechanical stuff and throw parts at cars. Now Ive been shown the way.
Interesting how so much on a modern engine can fail in such a manner! Speaking of wear, my daily driver is an old, high mileage Chevy with 4 bbl carb a with mechanical, pushrod driven fuel pump. The only real trouble I've had with the car is with the fuel pumps. After several fuel pump failures over the last 15 years or so, finally a new pump wouldn't fix it. When I took the pushrod out it had worn more than 1/4 inch shorter than a new one.
Modern engines are the worst ever. Great ideas on paper, but once the bean counters & engineers butt heads, you end up with low-bidder junk, like everything today. GM AFM failures (among many others), Ford timing chain, guide, and phaser failures, Ram DOD failures, and the list goes on ...
The list is sooo long. I guess the only positive to it all is it keeps me employed. But I agree, cars today just aren't built to live a long life.

Why is the cam journal worn.? Is it the kind of oil thats has a very low shear strength. Thus the journal is wearing? Do you need to find a oil that holds up better.?
Hey LJ, yeh i'm not sure. Again, this was a used engine, so I don't know its story. I only use quality oils, usually synthetic.
Mike Becker, Senior Instructor
Dang..missed it live again Mike. Your just gonna have to send me a text next time. Lol
Cheers Bro
Better late than never dude! ;)
Mike Becker, Senior Instructor
Not to ruin your day, but I'd consider dropping the oil pan and searching for ANY metal flake. I'd recommend inspecting the oil pump counter shafts for bearing surface wear/free play. ALL of this happened to my friends 2006 Audi 2.0t Quattro because of the destruction of the oil pump balance shafts. The overall cause was failure to change the oil frequently enough, causing a catastrophic failure of the entire oil pump assembly and total loss of oil pressure/flow. These engines are SUPER vulnerable to neglect.
Edit: Reach out to Charles, "The Humble Mechanic". THIS is his forte.
Yeh, you're right. The entire motor really should be torn down. I'll reach out to Charles and see what he thinks.
Mike Becker, Senior Instructor
Could high pressure pump failure cause ECM fuse to blow 🤔
Usually solenoid control valve is on low pressure side (intake) of high pressure pump, at least what I saw on Euro cars but everything has a variable probably.
Hey Ivan, thanks for watching!
Mike Becker, Senior Instructor
@@GoTechTraining Thank you for sharing knowledge and procedures
So Mike. Are you implying that the cam is worn so much that the pump is not being stroked sufficiently and therefore not building enough pressure? Because although the cam is marked up it doesn't look so bad as to really affect the pump stroke i.e. I don't think the lift of the cam has really been affected that much (nor the duration). Just my observation. That said I have no other explanation for the issue.
Just wondering?
Dave, yes that's what I'm implying. I agree it seems subtle but we are talking about a pump with a 1.5 MILI second on-time at wide open throttle. The smallest variations are increased in those cases.
Mike Becker, Senior Instructor
att least it looks much easier to work on the back of the engine in this transverse config compared to the longitudinal setup, but it might be harder to get to the belt and the rest on the front?
Hey G E, actually the belt man not even need to come off. The belt only drives the exhaust cam...you'll see in the next video. It's a weird engine haha!
Mike Becker, Senior Instructor
@@GoTechTraining that's true, but the belt is guaranteed to need changing at some point either way, and that's a breeze in the longitudinal cars. But the chain, tensioner, cam phaser and really the intake cam itself, imma just pretend they'll last forever in my A4.
👍 it's in good hands
Thanks for watching James!

Hey,do you know if code P2593 could be related to a faulty HPFP?
Sorry I type code wrong, is P2539
Sir can you tell me that how a person can become a coder and software developer for automobile after fsc pre engineering
Sorry, I'm not sure.
Mike Becker, Senior Instructor
hahhah the sad music at the end
hahaha gotch right in the feels, huh!? ;)

Why is this Gasoline engine have a vacuum pump? Whats its purpose? Is it because its turbocharged?
Yes, because of the turbo.
Exactly, because of the turbo. When a car is under "boost" there is no vacuum in the intake manifold.
Mike Becker, Senior Instructor
Dang, wouldn't it be nice if the follower had a roller like the gm one do?
Hey Bobby, a roller would have been ideal for this thing!
Mike Becker, Senior Instructor
After watching the video is it too late to change my vote?
Haha that would be cheating!!! ;)
Mike Becker, Senior Instructor
Looks like VW engines aren't big on longevity even with proper maintenance.
...or at least the 2.0t
I'm not sure it's all their engines. The 2.0 GDI Turbo is known for being problematic. I've definitely learned my lesson!
Mike Becker, Senior Instructor
Great Video other that all the Data that didn't reveal much of anything helpful? It apears that Manufacturing process of the 2.0T Camshaft(s) isn't as good as the 3.2L V6 Normally Aspirated Engines? or is it a case of Lubrication differences between the Engines? My point is that the 3.2L Engines don't appear to suffer the same high failure rate as the 2.0T SB? Randy AKA randog311 Retired Professional Wrench, Audi's are my Specialty
well that suck,need the cam ,i wonder it because of cam problem defect or lub issue
Hey Dan, judging by the TSB and the cam revision, I'd say VW has a cam lobe issue.
Mike Becker, Senior Instructor
See I had my hpfp and follower replaced and injector 1 after a new motor and still am getting this code. Car did sit for 4 years so it's a process. Shop said it is getting fuel so maybe the lpfp is not sending enough fuel now? I can't keep playing the parts game lol
Also had the sensor rail code show up replaced that too. It's lovely owning a ve product
That would be a good thing to check, make sure the Low pressure pump is putting out 3.5 - 5 bar (50-72 PSI), also make sure there is no damage to the camshaft lube that drives the follower.

Very common for today's cars to be almost disposable to certain point. Where get x miles past warranty and does it!!
It's frustrating, right Bernarda?
Mike Becker, Senior Instructor
Sorry it didn’t work out,but a good lesson nonetheless... 👍
Hey Nick, the main lesson in this one is not to buy a 2.0L turbo vw !!! hahah!
Mike Becker, Senior Instructor
an inspection mirror to see the cam lobe would have said forget it right off or just seeing the follower in rough shape.
Yeh, another viewer commented that I was in denial...I think that's true. I didn't want to have to replace the cam lol!
Mike Becker, Senior Instructor
hi i came accross your channel witch i subscribed to i highly recommend you watch one of rainman rays videos he shows step by step every bolt he takes out and boy he has a lot of subscribers you should make your videos a hour long maybe more im saying this because i think your a very good manhanic and im going to starting watching your channel will you please make your videos longer and go into more detail. by the way looking at taking out bolts is not boring thank you
That design of pump follower was bad from day one and they made you buy that goofy oil as a band aid to slow down from it tearing up.
Hey Jim, gotta love when they throw you band aids, right?
Mike Becker, Senior Instructor
Like your videos, but imagine you hit a sore point with customers that are so flush with cash that they would not prefer to try the same diagnostics and possibly save some $$$'s as you would with your personal vehicle.
Hey LSmiata, I'm not sure I understand what you're saying here.
Mike Becker, Senior Instructor
All these metal shavings.... not good. Some good oil system flushing is in order. Hopefully no other componends were harmed by these...
Yeh...i'm just hoping at this point it's gonna be ok.
Mike Becker, Senior Instructor
@@GoTechTraining its funny, because thats what every VAG owner is saying at some point. ;-)
Me is rocking a 2001 Audi A3 petrol with 241k km on the clock.
the pictures of it, someone didn't change the oil/or ran it out until idiot lights....
or someone dosed the fuel and all the bearings are matching that mess and should start hammering sooner than later, coin it a bum engine and try another, sorry to say that. but that's what my gut says
I wish I could. I really wish I was still within the 90 day warranty. This thing would have went back and tried another...but now i'm stuck with it.
Mike Becker, Senior Instructor
do you need any help at Go Tech > I'd love to get paid to fix my own vehicles (: (: (:
Hahah Russell, it takes 3-4 times longer having to film it :(
Mike Becker, Senior Instructor
Hope old cam is good condition ( $ave you from this.
Fingers crossed Over Load :)

Dorman Doesn't have a OE Solution ! :)
BOOO... I wanna see it as of 6 days ago :)
Haha sorry to keep you waiting :)

Vw junk lol
Hey Robert, live and learn, right? I had to learn my lesson the hard way on this one lol.
