Cam lobe wear on GTI

[ukdub]

Hello people

I have been a DUB head for many years and also a member of many forums.  I have posted the below topic on the UKMKIV's forum with no reply.  I think this is a big issue which hasn't had any response on that web site

Below is an exact copy of the UKMKIV's post.
Please read and take in

I have known about this for along time as I am sure so have many of you.

Awesomegti's demo car has just had it's cam changed under warranty as they inspected the cam lobe before fitting APR's High pressure fuel pump as it showed excessive wear.  All this in less than 20k.

Some cars in America have gone in 10k.

I think this is going to be a big big issue.  So give your local dealer a ring and show them the TSB in the link above, as the dealer who replaced Awesome's cam had no idea about the issue.

At this time it doesn't seem to affect the early GTI engines  AXX engine code.  (American's never got this engine code, only the BPY )

Could be very pricey out of warranty to replace.

Please search on the American sites about cam lobe wear as the above link doesn't show or tell a long long story.

Whats a cam lobe?

Sorry
The cam lode in question is the one that 'drives' the high pressure fuel pump.  There was a bad batch of cams that VW used in the BPY engine code GTI engine.  Not all BPY engine codes are affected but many are.   This is a 1k plus fix at least.  Some of you guys could only do 7k a year.  3 years and 21k on the clock you are out of warranty, could be a big bill that could be spent else where.

EDIT
The link in the first post seems to be dead

Please read the installation instructions for the APR high pressure fuel pump.  This pump in NO way is at fault for the cam lobe wear.

Ah i see, *nods and smiles*, so if my engine code isn't BPY im fine?

From what I understand its not just the cam at fault, the bucket that the fuel pump shaft sits in which rubs against the cam can also wear causing the same type of damage on later 2 piece cams, so I think this needs to be checked periodically to.

Hello Garry, this is where you hang out now.

Jim at Awesome is going to offer an inspection of the cam lobe as an extra to a normal service.  As Gaz says it is a cam lobe follower as well that is also part but not all of the problem, but problem non the less.  Many people say that the after market HPFP(HIGH PRESSURE FUEL PUMP) makes the cam follower fail faster with the bad cam.  That is a £20 part and 1/2 hour to change.  Glad to see the new 2.0t has a different design where the high pressure fuel pump is driven off the exhaust cam with 4 lobes on the cam and not 3 off the inlet cam as in on the AXX and BPY engine

Should add that the bad cam causes the excessive wear on the cam lobe on the standard high presure fuel pump NOT the cam follower.  The aftermarket HPFP could cause quicker wear on the follower but by much.  It is my guess and guess alone that the ED30 engine is fine as VW/AUDI have known about this for a long time.

So far so it seems.  I am AXX engine code with 60k with no problems running APR stage 2 for over 40k.  Still a worry though as I am out of warranty.

Hi Gary,

Did Awesome say anything about any lobe or bucket wear on your car when it went in for the fuel pump mod?
Did they swap out the lobe as they said they might or was all okay?

How/where do you find out your engine code guys please
