Title: a harsh lesson
Post by: gazon69 on January 20, 2013, 03:49:00 pm
This was checked back in may, hence my fueling  problem, now i got all sorts of sh*t to replace.

That is unbelieeeeeevable!

My fears would be around where the bits have gone! :scared:

Have you had a look at the cam lobe?

Dropped the oil and done a flush?

Changed the filter?

What does the hpfp piston end look like?

Well he hasn't said it's a cam follower yet.

Fooking disastrous if it is. Couple of oil flushes at least and sieve for the bits.

Post by: gazon69 on January 20, 2013, 04:52:59 pm
Right, yes that WAS a follower. The cam is totally f*cked. I can see through the head and yes hpfp is also f*cked. Yes it was replaced 18 months ago and checked last may and all was sweet with it. Just goes to show, from now on it will b changed every 6 months. Very harsh lesson indeed. Been told bits that broke off should be in head still as there's no where for then to go. Dont know if thats right though so dont quote me on that.

Post by: vRSAlex on January 20, 2013, 05:11:50 pm
The bits can get everywhere.  

Cam is around 150.  I charge around 4 hours labour plus parts plus oil and filter.

I check the follower on the vRS every 5k.  Any wear at all and it gets a new one.

All new customers to me get the option of having the follower checked when the come in.  Most say yes when I show them what can happen witth the worn and broken ones I keep.

Renew my cam follower at 5k regardless.  Going to make sure its checked after any track time or hard use too.

Post by: gazon69 on January 23, 2013, 02:06:29 pm
Yes mike. If i knew how easy it was to check in the first place then i would have prob done it myself rather than go on the word of other people. Shall also be replacing mine every 5k now regardless of whether is worn at all or not. Its a costly mistake to make i can tell you that. Put it this way, its my rod and piston money down the swan ffs  :sad1:

Makes sense really as the uprated HPFP produces up to 130BAR pressure and its powered by the cam so more fuel to pressurise, more pressure on the piston = more pressure on the follower and therefore more wear. Simples

It's opposite side of the engine to the cambelt and nothing really to do with it. Just a design flaw in the engine which VW resolved on the later TSI engine

Thats truly shocking

i thought VW America was honouring any cam foolower failures and associated failures like camshafts and replacing free of charge?
i know this is America im talking about but surely could argue the toss with UK vw?

I dont see how its the uprated HPFP that causes the wear? the map is what sets the fuel pressure not the pump?

If you have a mapped car and are using a standard pump it will still try to request the upper limit , it might not meet it.
Its still the same pump on the same spring and same cam follower , the piston is slightly changed to create more displacement / pressure.

Thats my understanding anyway

this is a concern!!!!!! my follower which was replaced November 2011 failed in December of last year.......exactly the same as yours has! split in half and not worn just literally the bottom fell off :driver: maybe there is a dodgy batch going around!
cost me a new cam
new set of autotech internals
hpfp housing
and my sump to be removed to get all the other bits of metal out

Nice one, ive been looking through my reciepts and i have nothing to say this has ever been changed. Do i get vw to do it (as i have 11month warranty left) or do i just order the uprated one and do it myself? As i don't want to void my warranty (although they wouldn't be able to tell i had changed it) or just leave it and if it goes they'll have to cover the cost of the damage it causes?

This must be more of an issue for remapped cars cause i'm sure mine won't have been changed in the 33k miles it has done.

But seeing as i'm planning on remapping in the next month or so I guess I should get it changed now.

why. Its a solid engine, depends how you push it i suppose. I know i'm pushing the boundaries with mine and it'llnonly be a matter of time before something else goes. The money i have spent on the repair for this was for rods and pistons . Knowing my luck i'll get those sorted and it'll bend a feckin rod  :sad1:

Please correct me if I'm wrong but from what i have read the 3 main causes for excessive wear/ failures on the follower are 
A revision 'a' cam that is worn where the uneven surface will literally eat away at the follower.
Uprated HPFP that put more pressure on the cam and follower
High revs which put more pressure on the cam and follower

It doesn't as far as I know.

It uses a roller follower (like a wheel) that rolls over the cam rather than slide over it like the TFSI one does.

IIRC someone made a roller follower for the TFSI but was £MEGA so cheaper to keep replacing your follower  :sad1:

Correct on all 3... well maybe the first 2 unless the rev limiter has been raised then 3

As an engine builder for 7 years this is my take on the fueling issues and fuel pump wear.

A worn cam lobe will give you less "stroke" to start with and putting a new follower against the worn lobe will not last as the surface hardness has gone from the lobe and will eat the new follower very quickly. I think some of the fueling issues on mapped engines will show up when the stroke of the cam is starting to diminish resulting in less fuel delivery, So the first port of call is to fit a HPFP this puts more force on the already worn surfaces and will in the end wipe the lot out just has the OP has found out.
I'm afraid if your follower has worn then the lobe is to... Eventually a new cam shaft and follower will be needed to be fitted at the same time.... The roller follower kit looks like it would be the way to go... very nice.
We were always told it is not good practice to put a new follower against an old cam shaft...  Well that's my take on it anyway  :wink:

Please correct me if I'm wrong but from what i have read the 3 main causes for excessive wear/ failures on the follower are 
A revision 'a' cam that is worn where the uneven surface will literally eat away at the follower.
Uprated HPFP that put more pressure on the cam and follower
High revs which put more pressure on the cam and follower

Correct on all 3... well maybe the first 2 unless the rev limiter has been raised then 3

As an engine builder for 7 years this is my take on the fueling issues and fuel pump ware.

Good post.  I think it's worth noting that in an ideal situation it would be great to replace cam and cam follower at the same time, but simple economics would dictate that for the vast majority of people this simply isn't going to happen - and replacing the cam follower regularly is still the most cost effective way of getting the most out of the cam and engine.

.
Broader question: Have there been any failures on mapped cars with standard fuel pumps and Rev.B cams that anyone knows about?

i guarantee that if you went to your local main dealer and asked them to check the cam follower for wear they would look at you as if you were talking marshon !

i asked my dealer for a price to check it , said he never heard of that part before then came back with a price of £150 !

Great info ARV_90,

I was more referring to high rev from track-days and such where the engines are really put to there limits and a lot of 2.0tfsi owners have spoke to changed to follower after each track-day.

Totally agree with you on the economics side of things fellas... probably do the same myself as the cost of replacing both cam and follower would be rather expensive. Come to think about it I have warranty from VW with mine .... so if it does fail they will be having it back. 40k and counting so we shall see.

Get what you mean on the track day   :wink:

I wont go down the route of fitting a new follower just for the sake of it as the new follower will not have the same bedded in contact area and would possibly make things worse.

I'm not to familiar with the revisions of cam shafts but if there are revisions it shows that the load on the lobe contact area was obviously not up to it... and would probably be a wider on any revisions, At a guess the earlier cams with a narrower lobe wont like having a HPFP on as its just to much surface load for the cam.

Just to clarify, its actually LOAD rather than high revs - you can rev a car on light throttle which will not require a lot of fuel pressure.

Foot to the floor (where the map is requesting lots of fuel pressure) puts the most strain on the follower.  :happy2:

R32 doesnt have the same fuelling system as the GTI and doesnt use a HPFP so you dont need to worry  :smiley:

@MIGHTYMULLET - If your car has 60k+ miles it will be worth replacing as a precaution as standard cars have failed also. The part is about £28 and can be replaced by yourself with one of the how-to guides on here, or a local specialist will do it for an hours labour

Good question... depends on how the fuel system works it may make a certain pressure constantly to a fuel rail then electronically meter it as required depending on demand of pressure and volume of fuel required.  If this is the case then load makes no difference the pump makes its design pressure regardless.

I wonder if the HPFP is able to give a bigger flow rate as well as a higher pressure, mapped engines would require both wouldn't they...

Maybe one of the tuning companies could shed a bit of light on it for us.

Fuel pressure is determined by your map. Increased pressure is requested when you increase load on the engine (ie put your foot down), and the pressure is adjusted as per the request. You can see the differences by logging on VCDS.

Generally at idle and light acceleration fuel pressure is low(er), and raises as you increase load with the accelerator pedal .

The fuel pump has a chamber which is filled with fuel and compressed by a piston which is powered by the follower. The higher pressure required means more fuel in the chamber to pressurise which takes more force to pressurise which in turn means more pressure on your follower.

Now, looking at the new pump im thinking to myself where the fook do the collats go. Hmmmm lets see. Looks as if my cam has chewed the fecker up along with the spring retainer :scared:.

There you go then ... the more power you request the higher the load.  

As to this problem only applying to engines that have been mapped or std that depends if the car you own has ever had a HPFP fitted in it's life.... how do you know as you see a lot of cars on here being "returned to std" to sell on .... nah then  :smiley:

Good effort Gaz.  That has been running on the cam for quite a while then.  Never seen one that worn before.  So the retainer and the collets were missing?  I'm fooking shocked tbh.

Are there revisions on these cams then ? I think someone said the earlier engines had a narrow cam... if that is the case do you know when the revision took effect. be nice to know if mine was going to suffer eventually.

that was towards the end of its life that it was going into limp mode. It was actually still making decent power somehow. If it was as quick as it was with a fooked cam and f/p, daren't think what its gonna be like when its all fixed up. :driver: knowing the luck im having at the moment it'll prob bend a frickin rod.

05, but the A cam has been found in 07 cars with the newer BWA engine code.  Nothing is consistent.

Listen guys. I think people need to relax a little. I never had a moments trouble in the three years i have owned the car up until now. If you are running a stock car or even a mapped car then tbh i dont think you have much to worry about. I am sailing very close to the wind at the moment with the mods i am running. I know this. As said its only a matter of time before rods let go i presume. I am thinking while sump is off shall i just bite the bullet and stump up for rods and pistons while im fafing around later, rather than take another blow later on.

Up until now i haven't heard of a cam follower go on a stock hpfp. I dont know if any of the tuners have heard anything or seen anything though.

I think you've hit the nail on the head there mate! :congrats:

This isn't a new problem and people/VAG have been aware of this for a long while now. It is obviously an oversight by VAG whilst designing the engine hence the reason they released a Technical Service Bulletin detailing the problem and what/how to change (even though most dealers won't have a clue about it!) :stupid:

That being so, it is still a bit of a PITA and so quite rightly people like us are concerned about it. I've changed my follower every 5k miles after I first heard about this problem and every time there has been literally no wear on it. The first follower was changed at 20k and that only had very minimal wear too after 15k of Stg 1 REVO. It really is a simple job and even for a retard like me it only takes 20 minutes (including a brew!) :happy2:

To the OP, I am truly gutted to see that this has happened to you. I do think that your making the sensible decision of doing the Rods etc whilst the sump is off (however expensive it is) as you sound like your running some serious power!???

Listen guys. I think people need to relax a little.I never had a moments trouble in the three years i have owned the car up until now. If you are running a stock car or even a mapped car then tbh i dont think you have much to worry about. I am sailing very close to the wind at the moment with the mods i am running. I know this. As said its only a matter of time before rods let go i presume. I am thinking while sump is off shall i just bite the bullet and stump up for rods and pistons while im fafing around later, rather than take another blow later on.

Up until now i haven't heard of a cam follower go on a stock hpfp. I dont know if any of the tuners have heard anything or seen anything though.
I think you've hit the nail on the head there mate! :congrats:

This isn't a new problem and people/VAG have been aware of this for a long while now. It is obviously an oversight by VAG whilst designing the engine hence the reason they released a Technical Service Bulletin detailing the problem and what/how to change (even though most dealers won't have a clue about it!) :stupid:

That being so, it is still a bit of a PITA and so quite rightly people like us are concerned about it. I've changed my follower every 5k miles after I first heard about this problem and every time there has been literally no wear on it. The first follower was changed at 20k and that only had very minimal wear too after 15k of Stg 1 REVO. It really is a simple job and even for a retard like me it only takes 20 minutes (including a brew!) :happy2:

To the OP, I am truly gutted to see that this has happened to you. I do think that your making the sensible decision of doing the Rods etc whilst the sump is off (however expensive it is) as you sound like your running some serious power!???

Best of luck to you and I hope you get it all sorted as soon as possible! :happy2: :pomppomp:

I don't think anyone is panicking about it m8 certainly not me I wont be changing any follower that's for sure... certainly not every 5k ...
All I was pointing out was that you may suffer this problem when you go to far with the mapping as it sounds like the earlier revision A cams "may" suffer damage due to the extra pressure when mapped past stage 1.

And as the OP said himself he is running close to the edge anyway so is expecting problems to arise.

Go on any make forum and you will only get to here about things that go wrong .... Plenty of people on here that have 100k plus miles on them mapped and still going strong ...
Very very true mate! That's the thing about a Forum, it's mainly used for problems and queries so can be alarming if you let it! :happy2:
I'm glad you're happy with your motor, that's all anyone wants. I wouldn't totally dismiss the idea of changing the follower now and then though! :wink:

I will see how it goes with the follower... Mine is a 58 plate DSG I bought it from a VW when it was just 3 years old and for peace of mind DSG and all that I took an extended warranty out with them. Had my days of playing with engines... although a stage 1 map is on my mind, and I blame this forum :-)

Sure is a dam fine car... Love it  :smiley:

I changed my follower in my 55 plate in the summer as it kept going into limp mode under load, mine was pretty worn and my cam probably needs changing going by what others have said on here, mine is completely standard with 107k on the clock, it's been driving fine since I changed the follower but will still go into limp mode if you say floor it going up a hill on the motorway at speed.

I bought my car from a non vw dealer and paid extra for a lifetime warranty so will have to have a look into it and see if I can get the cam changed under that.

Careful we aren't jumping from one extreme to another in this page. One minute: PANIC, next minute: DON'T WORRY.

Best advice is if your running big power, check it every 5-10k. Stock, every 40-50k sounds sensible.

It's a cheap part and for the peace of mind and to reduce the risk of big bills it's certainly worth keeping an eye on .

Sensible??  :smiley:

So here's where I'm at. I've just been offered on what I think is a great deal in an ed30 lump fitted. Instead of going down the repair route I'm going to bite the bullet and just swap the whole thing. Thanks to all who have given advice and helped me out in this situation. At the end of the day i think it will be better in the long run. At least the whole situation has given others insight of what can go wrong and how to avoid the same happening to them. Once again thanks guys

Two revisions on the cam, the earlier A one that has "soft" lobes and the more robust and later B one.

Has anyone had a quote from VW to buy the later 'B' Cam??

I've had 2 followers go, Stage 2+, one with Autotech and one with APR pump, car only gets used for track days though.

i guarantee that if you went to your local main dealer and asked them to check the cam follower for wear they would look at you as if you were talking marshon !

i asked my dealer for a price to check it , said he never heard of that part before then came back with a price of £150 !
lol lol



Yes, my local, dealer said the same thing, they have never changed one.

Wow, didn't expect that Gaz, but I must say I think you'll be faster and safer with the ED30 power plant. :happy2:

I gather the WMI and hybrid K04 will be staying?
