Poor guy says he thinks the cam and pump are ok :doh:

Problem is the cam and pump MAY look fine to an untrained eye.
There may not be any chunks missing out of it, or obvious wear, and the angle you can see the cam doesn't make it easy to spot the obvious rounded shape of the lobes etc.... Forgetting about the rest of the follower which will have made its way around the engine for a minute...
Some people don't realise how little the pump actually moves and how much difference those few mm can make to fuel delivery etc.
-
That is really bad ouch !! What type of damage may this of caused ?
-
At least a new hpfp and cam, poor bugger, thinking it was ok.
-
Dropped the sump off a friends GTI a few days ago to clean the pick up pipe and found pieces of his cam follower in the corner of the sump. They'd been in there for about 8 months
-
If the roller follower conversion wasn't so ridiculously over priced, I'd be doing it. You can change the DLC tappet 18 times for the same price :stupid:
-
I'd rather stick to my annual follower change. They come out looking almost new and it's a small price to pay. Don't think I'll be owning the TFSI for another 18 years to get my moneys worth
Downside is its a much heavier setup too, not great for high revving builds... but then again neither is the balance shaft assembly
-
Two horrible failures mentioned by Dan there which I why I wished I'd never bought the tfsi and stuck to my Audi cars lol
That picture of the Facebook guys follower is definitely a worry but he seems to think all is well but only time will tell or he will anyways :signLOL:
-
His new follower will be chewed to pieces if his cam lobe is fooked!
What I can't believe is how often this subject & carboned up valves come up! I'm sure if we were to look in a dictionary under carbon, it would say "See VW direct injection".
-
I've been in the same boat when I went to service my car and found my follower in the same state.

its because people don't know about them and find out on due course

and then?

New fuel pump, follower, cam and whilst there got the chain, tensioners, belt and water pump done.
But now have a p0011 code which the garage can't diagnose...I've narrowed it down to the vvt unit
-
Let's be fair - the follower isn't in any way deemed a servicable item by VW. Which is questionable. Some cars seem to barely score the surface after miles and miles, but others get this mess. Unless you're on a forum like this or you're into your cars you wouldn't think to check/replace it.
These cars are simple A-B jobs for lots of people out there. Plenty on long life intervals too, cheap service parts etc, pretty much getting the bare minimum care. I wonder how many are driving around completely oblivious to impending failure?

thankf for sharing as other will know if they read into this on here. :drinking:
Guy on Facebook seems to think all is well :thinking:
-
AJP you're right as I wouldn't have known about these failures if I didn't read up about them failing or firstly when joining this group and the guys who were kind enough to mention these parts may need replacing and checking :love:
Not everyone is clued up on cars hence we have these issues and expensive learning curves for some of us sadly but that's how it is an experience.

I did :smiley: I always thoroughly research a car before I buy it. I deemed the risks worth it against the cost of the parts and labour involved. The day after I picked up my Eddy, I went straight to the dealer and ordered a tappet, all filters, front and rear PCV and ordered a DV+ online, and they were all fitted the day after!
And armed with the knowledge of the common faults, I knew what to look for on the inspection / test drive too!
But yep, most of the google searching I did lead me to this forum, so it's been a brilliant resource!

Hear Hear Pudding... :congrats:
This forum has provide me with more knowledge about my Eddy and TFSI engines than I care to admit to colleagues at work . They already think I am slightly left field and a bit anal about my car but...
Its already lead me to :-
- Change and check my follower
- Change my oil from 5W30 to 5W40
- Book in to have the Thermostat and Cam chain done
- Refurb and replace my rear calipers
- Buy VCDS
- Replace and refit a genuine water pump
- Replace the cabin filter
Oh and be proud I have a lovely car and lots of fun with more to come ... Part of the enjoyment of these type of cars is the community and amazing things people do and share.

@ Ripstop
What made you change the oil viscosity? I have always used 5W30.
-
Reading the various views on running a lean burn engine and being able to drive mostly on dual carriage way allows me to get more benefit from a slightly thicker oil under temperature. I also reckon it would burn less than the litre per 5000 miles which is something I worried about until I found out these TFSI's are actually diesels in disguise :smiley: And also a very noisy cam chain which has quietened down a little since changing. 5W30 is a little too thin... and me coming from a traditional 10W40 camp was a leap of faith. I know its the VW specific oil SAE standard after years of testing but I feel better about just tweaking it.
Other than that no other reason. :wink:
-
5W40 (502.00) and 5W30 (507.00) are both specified by VW for use in the TFSI.
502 for fixed 10K servicing and 507 for variable 20K servicing. 507 has a lot more anti-sludging, anti-thickening and anti-wear additives than 502, simply because it's in the engine for twice as long as 502. Well, that's the theory at least but we all know TFSIs don't get 20K from a sump of oil! 1litre per 4000 miles consumption is considered good for a TFSI!
So in other words, there is no need for enthusiasts to use 507 because we change it out frequently, therefore a much cheaper 502 is plenty good enough. I use Mobil 1 0W40 at the moment, which seems to have a great performance / cost ratio and the engine seems to like it too!

Got an update for this a day after it was put on here but forgot to post up.
Chap pm'd me asking a few questions as he is going to need an inlet cam as the lobe wasbadly worn.

Hi friends, I have a question for you. I recently made an Instagram profile, at the moment I have around 3000 followers. But my goal is to reach 250,000 within 1 year. How do you think this is possible? Is it worth trying? I thought about what I can do about it, apart from unique content and beautiful pictures. I thought to buy real instagram likes (https://famoid.com/buy-instagram-likes/). Have any of you tried this? It would be interesting what the result was after you bought likes if your profile improved.
