Holy long winded.

Thanks for that

did you have to do a fuel sample test ? Same thing happend today on 2013 tdi. car wont start thry want to replace everything 4 fuel injectors, hpfp and etc. no metal shavings in the system but the car wont start. They told me my fuel failrd

@@brkbrk5205 I dont know how they determined it was the high pressure fuel pump, they just call me and said it was bad and needed to be replace and my car only has 60k miles on it so its definitely a VW faulty part its got to be from all the smog crap they have to put on U.S. cars

@@zydecbro good that they will cover that . I’m waiting an answer from Vw costumer care. Byers are the worst dealership here in Columbus OH. they don’t want to do any job under warranty. few years ago i had Vw passat 2012 that needed clock spring replacement guess what? they didn’t want it to fix it. Easiest thing is to blame water in fuel they literally set me up

did u say u will report them to the NTSB OR NHTSA ?

NTSB they basically knew I was willing to go the extra mile to make sure it gets covered

good to know guys around here seem to think that things are different there. I am changing mine on a maintenance interval of 100k miles so I never will have a bad one. too much money to change them after they go bad

in winter I used diesel additive on every or every other fill up and even my injectors were still OEM car ran as if it was electric so quiet and torquey

and yeah good point with your fuel filer I would replace it in between 10-40k miles depending on kind of diesel you use. at beggining I didint know about importance of diesel quality I had to change it every 10k mile/with oil change but once I started using additives without hesitation I would go 40k on filter and replaced it only as a precaution measure

I would sure try. Make sure the fuel was not contaminated they will reject it for that.....But the fuel station will cover it.

@@Mikefngarage already spoke with official dealer he said warranty will cover it

Replace the rail pressure sender and the rail pressure regulator. If those are clogged with microscopic metal particles it thinks the pressure is too high and opens the fuel bypass back to the tank. You will never reach a high enough pressure (2,000 psi) to spray the diesel through the injectors. The pressure sensor also has to be reset in the car's software via VCDS or it still doesn't work. You can buy both for $132.00 or buy the entire fuel rail assembly for much more. Make sure you wash out the fuel rail too. I am presently working through this on my 2009 TDI Jetta. Purchased a rebuilt HPFP from Bosch for $350 (same length warranty from Bosch as a new unit $1,600.00). Replaced fuel tank pump and sender, fuel filter, rail pressure sender + regulator, and blew out the lines. Last step is to replace injectors ONLY if needed. Car was running fine at 75mph when it suddenly died but smooth to the stop. 254,000 miles on fuel system. Loosing fuel pressure would do that more than 1 or 2 injectors clogged....it would have ran like crap until it died. Rebuilt injectors are ~$100 each. You can verify it is the HPFP with ease. Open the pressure regulator on the pump itself (top of the pump). It only requires removing two small torx screws. If there are metal chard in the pump under the regulator it is toast. The problem with the HPFP design is that the part driven by the timing belt is like a cam lobe. It comes across the pump rod pushing it forward to pump fuel. The circular shaft it is in is a smooth bore and the pump can wander up to 90 degrees away from the correct position allowing the pump to rub through the cam lobe rapidly. It could all be fixed with a key slot to prevent it from rotating out of position but that would cost 3 cents more to do.... but then they couldn't charge $9,000.00 for the repair. There is also an alternate HPFP that can be used (modified) CP3 in place of the CP4. the CP3 also does not have to line up perfectly with top dead center since the CP3 has 3 lobes and the CP4 has only one.

Potential Back pressure

@@niaedwards382 sure just put a big filter on. Back pressure only upon catastrophic failure.

It comes in my skoda superb and there is no engine sign .. I am not sure what to do

hmm I have never replaced it yet because it was already done when I got the car so I dont know exactly where it is. . I am replacing it right at 100k miles before it goes bad. on a maintenance interval. so I dont need to replace any other parts.

Mike F well you first need to know how to replace the timing belt and evrything involved because the hpfp is driven by the timing belt. It is not a easy fix thats why it is so expensive.

Mike F kzfaq.info/get/bejne/nKeZaZlorZ2xYo0.html

Yea I was just looking at the pump driven by the timing belt. I am 100% certain I could do the job. I just have never done it. Mistaken for the intermediate pump on the driver side of the engine.

Mike F i'm preparing myself for the same job. Already did the belt and evrything. Preparing just incase. And this problem also happens in europ. I'm from the netherlands

CBEA/CJAA

Any advice???

parts available at Cascadegerman.com really cheap for original equipment stuff....Not too big of a job but pretty big. .Also Look up cp3. the CP4 pumps are complete bosch engineering failures. upgrade. Change to the CP3 and its smooth sailing. No more issues.

genuine rebuilt" lol

@@MattBerrymotorsport and? 🤷🏻‍♂️

yea they are really good those hondas. Honest gas mileage. the only thing better on the tdi is the city mileage is a few miles better and highway is 1 or 2 miles better. More problems
