I’m all for making the job easier, less chances for mistake especially when it’s hard to access the timing belt tensioner. My recommendation for anyone doing this job just remove the engine mount and make sure u have a jack with a block of wood up under the oil pan, I believe they are stretch bolts but you can buy a complete kit for like $40.
Hi, I watched your video and thank you for doing it. About the timing belt. It is not necessary to remove it... Just loosen the tensioner. Yes you are correct that "most" of the slack is on the opposite side of the engine but there is enough slack to remove the idler pulley to the top left of the HPFP and the belt is way loose enough to remove the sprocket with ease. :o)
You could and I'm sure there more ways to do this than the one I have shown. That said as long everything lines up and you feel confident do this my friend any way that makes since. 👊😎

the fogs were stock on Canadian TDI and optional in the US, so people were picking them up when the crushed the Canadian TDI's and owners pulled them off pre crush. to resell
Great video, thanks for putting it together. I just had this happen and was wondering how to take the pump off. I have the timing kit but not the same one you have. What's the kit called?
did you have to change the fuel injectors I did the same without changing fuel injectors no start low fuel rail presure . just wondering if the injectors are bad
did you have to change the fuel injectors
Very informative, thank you for a well made video =)
Hoped it helped my friend. Thanks for the 💚
were you able to find replacement parts for these pumps? IF so where can I purchase?
Car went into limp mode on me and engine stalled going around 20mph, pulled over and my car wouldn’t start at all. Battery went dead too so I called my mechanic who told me my alternator blew and then ruined the battery. I had similar symptoms to a hpfp failure, I’m praying to god it’s not that though I can’t afford a 6-7k repair on a 2011 golf😭
Hi mate, I’m replacing my timing belt on my 2.0 tdi CR engine which has had a timing belt done in the past. The issue is I’ve locked the crank and cam shaft in place but the tab to lock the high pressure fuel pump is about 45 degrees away from the hole, almost as if the last mechanic who replaced the belt didn’t lock the fuel pump in. Do I pull the fuel pump back round and lock it in before putting the new belt on or do I just mark the old belt and replace it as it is without locking in the fuel pump? Some people say the timing is important on these pumps and others say not so I’m not sure how to go about it. Cheers
So first off the fuel pump on these has nothing to really do with the timing the engine.(there is torsion system that is involved with it but that on the cam side of thing and it requires vcds or equivalent to mess with ). The only reason you need to lock up the fuel pump is for removal of the pulley stack on it.
I include a write up you will probably find alot of value you and should help you. It help me when I learned how to do these the first time.

I’m doing this on my girlfriends audi a3. My bottom most timing tool is lined up, but the uppermost sprocket is 180 as if a previous mechanic installed it upside down. Can you please help
That is a touchy one. Send me a dm on the gram, with some pictures and will see what's what.
Where do we get this kit to time in the pump?
There should be a link in the description for the kit I purchased it off Amazon so it is an affiliate link.
@@TheRwdyAudi there is no affiliate link. If you have a name of yhe kit or anything I can look up
I'd appreciate it
Maybe the pin on the follower broke ? and then its worn away ? because why wouldn't they have a pin to keep it aligned ???
You would think they would have, but they didn't.. only the gas cars had a follower with pin. I'll post a photo in the community tab with the different gas follower vs. tdi cp4 follower
Do you have a link to the counter hood tool you used for the pump?
My bad I thought I had this in description, thanks for keeping me on my game.

So you dont have to drop and clean the tank and replase the tank fuel pump a secondary pump
Very rarely have I had to replace the intank pump the amount of metal that returns back to tank is so small(not to mention it would get trapped in the pick up sock on the pump it self) and even if it where to come up the line it would get stuck in the filter before ever being able to cycle back to the hpfp... it physically not possible.
As for the secondary pump, "dirty or contaminated " fuel would never enter the aux pump as it only feeds its filter, and fuel can't go back wards.
One thing I didn't cover that should be done is that both the fpr sensor needs to be clean and possibly replaced if they are showing faults.
All of this typed out each case is different and should be treated as such.
Best of luck, my dude, I hope this helps
Do you have video of the rebuild?
Sadly no we didn't end up doing a rebuild the only parts supplier I could find to get the guts was in turkey and the lead time was about a month to get the what we need, which didn't line up with the customers needs. 🤞maybe in the future we will get and opportunity to do it
Do you need to program the new pump with a scan tool ?
No you don't need to program or adapt for the new pumps
You are supposed to prime the fuel system with the vcds tool though.
Open internet. Print all. Throw printed stuff out the window. Grab hacksaw and start cutting
😂😂😂
Can the cam follower be replaced?
Yes!! it can be
@@TheRwdyAudi have you rebuilt yours or just bought a replacement pump
This was service work for customer. But in this case we had to replace the pump because the follower turned side ways(common failure) it completely ruin the unit(there is a company in Ukraine that sell parts to rebuild my customer decided not go this route). Ultimately replacement of the cp4 pump was a better option. Hope this answered your question
oh now that its for views you can work on a TDI? cringe
Not exactly... but it is alot easier when it in my shop. Get your on tow truck and I'll get it figure out.
