So I have all of these notes as to what I am going to type to him when he sends the quote. Anyone wanna fix it for me?
"Could a High pressure fuel pump starting to go out cause this failure, and did you check to ensure that the high pressure fuel pump is still working correctly?"
In order for camshaft to break, something had to cause it to break. Jammed lifter? High presure fuel pump on its way out? Could this cause that to happen We need to find the root cause.
Photo evidence of what exactly. How did the cam break?
Also look into replacing timing chain tensioner?
Possible concering issues:
Tiny oil passages
Metal shards
I believe it to be a heat treat is due from the factory and vibration caused an internal small crack to make it all the way across. 100% manufacturer defect. Wonder how big of a batch VW got just like it. I also think there is some risk of the intake cam doing the same thing if it was manufactured at the same time.

For that to happen, something stopped it from rotating on one end.
Also, - camshafts don't just fail. Google VW 2.0T camshaft failure. You won't find much.
No way it was axial load guys. There is a chain at one end and bearings/races holding it in place. This is manufacturing defect.
He said torsional, not axial; words and definitions matter (aka english motherfucker ) . 100% a torsional load caused this failre factory defect or not.

I'd also ask for photo evidence of what exactly failed. Then share here. I'm legit curious how a cam "broke"
Wiped out a lobe? Maybe...but then something else major is wrong.
he did post a video, the fucker snapped in half in the middle. Its legit some shit I've never seen of or heard of. BUT... that kind of thing does not 'just happen' esp after 70k miles....
and the fact that they are telling him to do the intake is straight up robbery
Oh, I missed the video. Things move too fast. Oh well.

My guess would be that Chris took some time off because he has read the dialogue on this page 1,345 times and decided to spend some of his free time doing something besides beating a horse to death.

Hello. So basically service manager just called me, said they have checked for engine leaks, air stuff (i don't remember his word) and everything seems to be okay, no bent valves, etc. So I guess it broke in the best possible way? He is recommending replacing BOTH cams (since the other one could go at around 80k miles), instead of just one. He said even with that fuel pressure light there was no way they could've even detected it would have been a camshaft cracking, it's an extremely uncommon problem.
He is sending me a quote and his recommendations. Will post it here for some suggestions before I go to VWoA. They did open the engine up and not charge me because I take care of the car and have paid a lot for their services.
Why replace both cams, that makes no sense at all. Replace your broken camshaft and then replace the car.
Replace the broken one then drive the car over to :Zillerman: and trade for a nice Mazda3. Do this before the end of this month.
Where are these mangos?

don't be a sucker, please. This is now painful to me.
Don't do the intake cam. Cams don't typically fail, ever. And they dont fail in that way unless something is wrong somewhere else usually. I'll bet your HPFP is shitting the bed. I maintain there is other fuckery going on with your car and this
MAYBE do the timing chain tensioner since they will (likely) have to touch that to do the cam.
MAKE SURE YOU ASK THIS, IN THE QUOTES!!! "Could a High pressure fuel pump starting to go out cause this failure, and did you check to ensure that the HPFP is still working correctly?"
THEN POST THE RESPONSE EXACTLY, not some "blah blah blah i think they said something about the flux capacitor not getting enough volts and that it needs a better source of neutrinos" IF YOU DONT POST A QUOTED RESPONSE I'M DONE HELPING YOU AND WILL REVERT TO MAKING FUN OF YOUR SITUATION.BECAUSE IT WILL BE YOUR OWN FAULT.
We can't help if you don't give us accurate information.
, is spewing actual here. Listen to him and obey.

I don't agree on doing the timing chain tensioner IF you are going to do the smart thing and trade the car in asap.
Therefore, you should probably do the tensioner.

100% agree. I know the least about cars on here, but I think it’s time to get rid of this car because it will have more problems.

You got it man. When I get the quote I will respond back with that exactly. He did mention the chain tensioner or something like that too.
You need to do better with your communication.

Who wants to start a pool on how much forks over for his broken non-engine part? I'm going to say he's $1700 out of pocket.
There was a torsional fracture about halfway down the cam.

Also, - camshafts don't just fail as a wear item and don't have intervals. Google VW 2.0T camshaft failure. You won't find much.
All
Broken camshafts are a thing with VW though. Happened more often in FSI days where the cam follower would shit out and jam the shaft. But the TSI engine isn't radically different than the FSI, and still drives the HPFP off the exhaust cam, and as such is still subject to some bullshit type problems.
VW just recalled 92,000 cars for possible snapped camshafts from 2015-2016 model years. Apparently the vacuum pump was driven off the cam and if it broke you'd lose power brakes and possibly crash according to NHTSA, so they forced a recall.

Chain at one end driving it, fuel pump at the other, with 8 valves in between. Plenty of opportunities for things to fail and cause it to jam.
If this is what happened, as I believe it to be, what are the odds that the chain stretched at least somewhat as it encountered sudden resistance right before the shaft snapped?
Methinks fairly high...

Possible I guess. I'm thinking the cam phasing would account for that. But who knows and who cares crang should dump this piece of shit car.
