I do not have the part number for HPFP. I just replaced the seal on it. I tried finding it. and i am not sure, but it looks like all 1.4 tsi with 103-125kw use: part number 03C127025T. I think you would be best of asking a VW dealer to be sure its the right number, before buying anything, they are not cheap parts
Hello, I have a question about the vw golf 5 1.4 103 HP 2007 auto (1k1). Is the small cylinder inside the high-pressure pomp the same as the one we can see in the video, or does the production number 711024410 fit?
I didn't know at first.. but it has a fairly small needle bearing in the roller. I checked because I thought it was a little noisy from hpfp. And the bearing was quite worn and noisy when dry. Thought it was best to change it.. My local vw place never sold one before this.. so it might not be a common thing. Just made sense to change when it was already out..
at first it was because of tapping, and I was told it had same follower as the 2.0 gti. When I got it out it was the roller type follower. But the bearing in it was worn quit alot. IT had a lot of play in it. so I chose to replace it. If it fails the cam will take damage. My local VW dealer never sold one before this. So it might not be a common thing to do
@@r.tran2 I just changed mine today, same exact cam follower as yours, it's a 3.0 Tfsi and the same exact tapping noise. I'm yet to see if the tapping noise is gone on a cold start. Did the new follower sort your tapping noise issue? Excellent video btw, great content
And they would be right. But looking at live data. You'll get an indication of what state it's in. Cam advancement or timing advancement, I think it's called. Between 0-4 with smooth idle, everything is good. Above 6 , indication of chain stretch. Idle will be affected, and codes start coming. This is what I was told.
@TzouPhotography I think it's more likely the pumps doing that. Low side not providing enough to hpfp at high rpms. Or clogged filters. But if that little bearing fails, it could destroy the cam and/or engine. That's why at high mileage, it's a good idea to renew the cam follower.
I've got the exact same engine and I have a fault code of P2293 with the HPFP (mechanical malfunction - intermittent). From 40% engine load it throws this out. Also - I'm limited to 3K revs and it jerks violently if throttle is more advanced. So, I'm not sure if I have a low pressure issue, or the HPFP itself it not producing enough pressure. Also, i'm not sure if the HPFP is a combo of solenoid activation or purely cam lobe-driven actuation. From the looks of things - it only has one thrust sensor, unlike the 2.0T GTi variants, so probably the latter? But my specific issue here is a likely out of timing ( - I have all the symptoms of a skipped chain). I'm having a new timing kit installed soon to see if it will remedy this (obviously also checking the low pressure upstream fuel delivery) if not - I will rule out this hypothesis and would be down to an actual mechanical malfunction on the lobe/roller/HPFP. Keep you guys updated.
What's the part number on that HPFP? I can't find a replacement anywhere.

I would think it has the same one as in the video. With the roller.
Only the 2.0 have the other one.
@@r.tran2 thanks for the info
and maybe you can tell me from which site I can buy such a type, because I think this type is very rare
@@KekszMorzsolo69 only available from VW dealers. I couldn't find it anywhere else. It's about 110€. Or 800DKr.
Where can i get that custom air filter?
it is a K&N filter. it was already on the car when I bought it. I don't know part number for it. you will have to find your local K&N dealer
@@r.tran2 thanks i found one on eBay
How did you know it needed to be changed?
I didn't know at first.. but it has a fairly small needle bearing in the roller.

@@r.tran2 Det lyder godt. 1 mindre ting at skifte for mig ;)
was that loud tapping the reason why you change the follower? it was quite happy after start probably until it was all lubricated?
at first it was because of tapping, and I was told it had same follower as the 2.0 gti. When I got it out it was the roller type follower. But the bearing in it was worn quit alot. IT had a lot of play in it. so I chose to replace it. If it fails the cam will take damage.

@bogathlorant yes it did remove some of the tapping. Still some in the high pressure fuel pump. But that's normal I think.
I have the same engine and just rewatched the startup. Mine does not have Any ticking. Has the chain been done? And are you using 0W/30?
Using 5w/30. I think the chain has been done. But not recently, I think 🤔 chain value is within the recommendations still.
@@r.tran2 On these engines I don’t think you Can measure the values? It will only warm you when the timing has been skipped
I can look for how much it is adjusting the timing. Same as the 2.0. Atleast as far as I know.
@@r.tran2 I did not know you could do this on the 1.4 TSI… VW says to take the entire side of the engine off to check it

This is what I was told.
They say this can cause fuel cuts at high rpms
@TzouPhotography I think it's more likely the pumps doing that. Low side not providing enough to hpfp at high rpms.
Or clogged filters.

@@timbitzzz HPFP is purely cam lobe-driven. mechanical only. hope you get your car sorted.
Nice broo
