Title: I need a new HPFP (and quick) - any advice?
Post by: Fizman on March 27, 2011, 01:43:50 pm
Hey guys,

My '06 GTI hasn't been driving great the past week or so. I was getting a bad lag once I reached 100km/ph. Then over the last two days it really started driving like a dog. Really bad misfiring from early on, not just at the high end.

Brought it to my mechanic on Thurs night and he ran a diag. It returned the code P0087. Fuel rail / system pressure too low. He took it off me Fri night and rang me yesterday to say that I need a new High Pressure Fuel Pump. Any suggestions as to where I should order one of these from? The car is stock as it is, and I don't have too many plans for upgrading it in the near future. I do a lot of driving with work so the sooner I get my hands on one the better.

Any suggestions greatly appreciated guys!

Have you checked other things first such as cam follower and sensor.

Me personally no, I'm just going on what the mechanic has told me.

I did a small bit of searching and it seems that the cam/sensor/follower are made from softer compounds than the pump apparently (correct me if I am wrong). Would this mean they would typically wear quicker than the pump. Is it possible for them to be ok and the pump to be damaged?

Unlikely as the pump is damaged after the follower has been punched thru. The pump's plunger then rides "unprotected" on the cam lobe damaging it.

Therefore you must ask your mechanic if he removed the hpfp to physically check on the condition of the cam lobe and its follower.

If you do need a new hpfp I would recommend sending yours to PDT and getting the Autotech internals upgrade. I found them to be extremely professional throughout and I was more than pleased with the results.

Ok I'll ring and ask him if he has checked the cam lobe/follower. Any recommendations as to where I could source all of these parts online? I'm based in Limerick (Ireland), so I won't be able to bring it to any UK location (assuming that PDT is in the UK).

I've got a spare HPFP if your after one. I had a lowish torque figure after my PDT remap, PDT said it might be my HPFP , I put a new one on, and it made 5bhp less with the brand new pump on. I'll sell it for £40 delivered if youre interested. Its around £170 new from the dealers, could have it  posted tomorrow for you?
It would also be worth fitting a new cam follower while the pump is off aswell :happy2:

Just spoke with the mechanic. He will be checking cam lobe and follower in the morning. HeavyD, I may very well take you up on that offer! Is it in good condition? What kind of miles were put on it before you took it off? If I do go with your good self I might ask for a photo if possible.

I reckon I'll definitely be looking at a new cam follower alright, which isn't an expensive part. Fingers crossed the lobe isn't damaged!


Quick question regarding all of this work: My timing belt is due for change soon too. Would I be better off doing all of this in one quick, but very painful process? Or hold off another 6-8 months or so and do the belt then?

It had done 36k.
I had it on ebay the other week, so its still all wrapped up. it was this one
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=290536756173&ssPageName=STRK:MEUSX:IT
Up to you mate, it worked, It made better power than the new pump. I just wasted money on a new pump for no reason. Its a half hour job to swap over, and doent interfere with the timing belt, so I wouldnt bother changing that yet if I were you

That looks in good nick in fairness. I'm gonna wait until I speak with my mechanic again tomorrow after he fully diagnoses it. Decent chance I'll order it off you tomorrow night though. I'll keep you posted. Cheers.

Also as your car is an 06, did it have a recall for the low fuel pressure sensor?
Title: Re: I need a new HPFP (and quick) - any advice?
Post by: Fizman on March 27, 2011, 07:16:38 pm
Not to my knowledge. I only own it since Feb 2010. It has full VWSH alright but no mention of recall in the logbook. If I had to guess, it probably was not recalled. Would this be something else I should look into replacing?

Just looking through the cam follower options seeing as I will most likely need a new one, do you guys reckon I should by something other than the OEM VW one? Something along these lines....http://kmdtuning.com/?_a=viewProd&productId=1426

Apparently 20k longer life span.

No, stick with the oem one.

Any good UK/Euro sites to order from? Majority of the ones that are popping up for me are US based. I'm in need of this asap so the closer to home the better.

Have you not got a local vw dealer?

Indeed I do. I just would have thought prices would have been far better online. I'll give them a call in the morning anyway and compare to the online equivalent.

I think I only paid £20 for a cam follower from the dealers the other month?
Title: Re: I need a new HPFP (and quick) - any advice?

Cool, I'll check them out in the morning. I'll be in touch re that HPFP.

Ok, I'm f**ked by all accounts.

Mechanic rang me this morning. He said my cam shaft has a LOT of damage. The cam follower is completely disintegrated and he said that the  push rod on the HPFP drove into the cam shaft.

In a nut shell, I need a new cam shaft (€237 ex VAT), a new cam follower (€26 ex VAT) and a push rod for the HPFP (apparently the HPFP itself is fine). However, he spoke with the local VW dealer and the push rod cannot be sourced individually, it comes only with the pump itself apparently.

HeavyD.........does your HPFP have it's pump rod in tact? If so I'll take that off you, and as soon as physically possible.

Post by: Fizman on March 28, 2011, 12:27:34 pm
Guys, just in case HeavyD isn't back online anytime soon..........do any of you know if the pump rod for the HPFP can be sourced on its own??

I need to get the wheels in motion with this thing asap as my mechanic is on hols on Friday and I don't really want my car sitting up while he's away.

Post by: martziniuk on March 28, 2011, 12:50:32 pm
I would get the pump as a whole kit, if the rod is bust chances are the seal inside has split or deformed. You don't want petrol in your oil as there is more chance this could happen again.

Not necesaceralry , i was reading a post on the American forums the other day and it says that VW has warranted cam followers up to 120,000 miles , because of so many foller failures and all work if 1 fails is paid by VW.
Would be worth checking out VW customer services mate.
Title: Re: I need a new HPFP (and quick) - any advice?
Post by: heavyd on March 28, 2011, 01:10:51 pm
Contact VW services first then, you might be lucky :wink:
Yep, the pump rod only comes with the pump. the one I have is fine. alternatively, there was a pump rod in the for sale section the other week if you want to rake through the for sale section, but then again, if its being running on the cam lobe, I would have thought it would have been running at all sorts of angles so the seal would have been damaged I would have presumed.
Like I said before, if you definitely want it, I can have it sent by royal mail recorded post this afternoon, just let me know.
either PM me or just send me an email

Right, spoke with VW Ireland today (customer services). The guy made out that he has never even heard the term, cam follower. Surprise surprise. Spoke with him for 10-15 mins and was just going around in circles getting nowhere. Rang three local VW aftersales garages and none of them came across a cam follower issue before. I'm hardly the first Irish case! Wouldn't surprise me.

Anyway, took a spin out to see the car tonight. Mechanic showed where the outer part of the cam shaft (possibly the lobe) was worn from the rod. Am I correct in saying that the follower is a pretty small part? I had imagined a much bigger part going on the pics but if what I had in my hands was the follower it was pretty small. It's 'cap' completely worn too.

Looks like I need a new inlet cam shaft, follower, and pump rod (so essentially a HPFP). I think I'm also going to take the hit with the timing belt and get a full kit (tensioners, water pump, etc). Bad times.

If you do a search for "cam follower", there's pics of what it looks like and what it's like when it wears. Looks like a thimble to me!  :grin:

Post by: bacillus on March 28, 2011, 09:53:44 pm
Sorry to hear of this outcome!   :sad1:
You should also get your oil changed as there are probably pieces of metal from the perished follower mixed in with your oil.
Title: Re: I need a new HPFP (and quick) - any advice?
Post by: Fizman on March 28, 2011, 10:40:49 pm
Yup a thimble would describe it. Yes, my mechanic said he will do an oil change for this very reason.

I know that this is an expensive time but do insist that he uses longlife oil (e.g. castrol edge 5w-30) for the refill as apparently poor oil choice may hasten the follower's wear rate amongst other things.

Already done! :)

Looks like bread and water for a few months!
