munched engine...ouch! not for the faint of heart

Arthur, give up on your paranoia and just enjoy the week-end. Do please ask John Roberts to do any checks you require, and then do please reveal the results on this thread. And apologise if required.

A newbie has come on to the forum, it's not good to treat them with suspicion and accuse them without any foundation. You did that with me, and you were 100% wrong as I am confident you are now.

so now I'm paranoid? lol
let the readers decide...very suspicious, especially considering your first posts concerning HP rating & deposits...
troublemaking instigator = sop

I will never apologize to you...you are the one who needs to...
to EVERYONE

funny you mention that...you were full of BS your first posts too
(not much has changed)

don't fret your pretty lil' head about me...my weekend is going just fine, lol
what a crock of shyte, your 'concern'

that post was a set-up...and I'm paranoid?
you're talking (posting) with yourself!!!

Arthur, just cool down and have a good week-end

[ArthurPE]

Arthur, just cool down and have a good week-end

are you drunk?

I'm having a great weekend, but again, thanks for your disingenuous feigned concern...

it's 72F/45% RH in my house?
that's pretty 'cool'...

2 engines, same issue...in a few days...
since all engines are the same, and all suffer deposits to ~ the same degree...
ALL engines will eventually, or have failed (scored cylinders)
this is not 'random', it is a consequence of the design, a 'normal operating conditon'
it's only a matter of time...

14,000 cars at $20k per engine...$280 mil to recall

this deserves investigation...

this is not a random manufacturing defect
it a consequence of the design, and it is an inherent problem applicable to ALL cars...therefore all will eventually fail!

it may be something like bad oil maintenance, improper break-in, etc., or even just a couple of manufacturing defects...
but both posters have stated that Audi confirmed it was damage due to deposits...their words, not mine...in other words Audi has acknowledged that deposits (whcih affect all engines) destroys them...again, their words, not mine...Audi has acknowledged the issue, according the the posters...

Look forward to hearing the results of your investigations.

As to k3kur, I would be interested to hear his story so give him the opportunity. I notice however his car is delimited so I gather this is only done with remapping so I wonder what other work has been done to his car? And could that contribute to his issue.

Did psg001 not get a new engine also because of engine scoring?

psg001
new engine or buy-back due to HP?

it's you who needs thanked
it's you who have stated that Audi has acknowledged all engines will eventually fail due to deposits and will be replaced at no cost...kudos

[ArthurPE]

I stand corrected, it was replaced, but not for deposits scoring...
appears to have been a random failure of hardware...not deposit related

update from Audi last week.

they think a bolt from the inlet manifold has snapped and caused the damage inside one of the cylinders (they reported earlier seeing some debris). anyone heard of this sort of thing on an RS4??

It was just an answer phone message that was left hence no more details, they are getting on with the repair. To be honest am just letting them get on with the repair

hopefully they can get this sorted out in the next few wks and I can have my car back. Got an Audi Q5 last week with the 2.0TDI engine & quattro, its much quicker than the insignia.

P_G ,I bought the car dec last year picked it up jan ,on the way home the epc light came on ,took it to dealers they said it was no3 coil pack ,when driving it it felt down on power compaired to others I have driven ,I took the car to dastek to be rolling roaded the car made 378 bhp and was also down on torque ,have the printout someware. I dont use the car that much but when I do I dont hang back ,It then went back to audi they said it needed three air solanoids and it had a split pipe ,the car then went back in two weeks ago and this is whare we are now ,they stripped the inlet manifold off and there was carbon build up ,very bad dont think it had ever been cleaned ,then they wanted to take the heads off to check the burn pattern ,when they had the heads off the scoring was then seen ,they phoned friday midday to say they were going to fit an engine ,thats all I know untill monday ,

P_G the car had the latest software update ,It did over 155 so thought it was delimited lol

which dealer?

and Audi said the engine was destroyed due to carbon deposits?

what year? still under warranty?

Unlucky throughout, sorry to hear your experience.

That said it perhaps does hark back to what was being said on how excess carbon build up happens and partly attributable to the way they are driven? It perhaps shouldn't be the case but maybe is. You say you don't use it often but give it the full beans when you do, whereas me I use mine daily but only occasionally give it full beans and touch wood don't have the issues you have with your car. Driving style may influence rate / quantity of build up?

[ArthurPE]

look closely at this picture...it's very revealing, very good eye to have caught it...

without seeing orientation we can't tell for sure
but this is either the rings being deformed and the gap edges doing the scoring (notice, nice consistent, parallel lines grouped tightly) or possibly the piston ring circlip has become dislodged...

all the other scoring runs top to bottom, full stroke, that is consistent with rings...deposits would be far more random (if they could scratch at all) and not run consistentaly full stroke...as most of these do

was this engine ever run on race fuel? 100 oct?

Ok, I changed my mind....

[k3ukr]

It is at the audi garage closest to me
It has done over 40000
Yes it is still under 3 years old and in warranty
Audi didnt say that, they wanted to check the burn pattern thats why the engine was stripped ,nothing to do with carbon build up ,when the scoring was seen thats when they said it needed an engine ,the car is in warranty with FSH so the cant really say that it cant be fixed due to not being serviced,and they cant fix the engine, probably could but it would a lot more money

what is the name of the dealer...I found 4 (relatively) close to your location

NOTHING to do with carbon build-up? thanks

.... both posters have stated that Audi confirmed it was damage due to deposits...their words, not mine...in other words Audi has acknowledged that deposits (whcih affect all engines) destroys them...again, their words, not mine...Audi has acknowledged the issue, according the the posters...

If I'm one of them you are referring to, Audi didn't say this to me. Be very careful accusing me of something I didn't say. I told everyone that Audi said it was wrong oil, but it's NOT wrong oil.

Also, if you pick the other picture you'll see the score marks are different. You know this.

Finally, a warning to everyone else. Be very careful what you post. Whatever the conversation Arthur had with Audi of America, it made it all the way back to Audi Australia, and then to my dealer. They have indicated they will not allow me to take more pictures. If you think for a second Arthur is working to help us understand the RS4 (like a contributing member of rs246 would) think again.

To the poster with the problem, be very careful what you say in Arthur presence. I wouldn't put anything to him in PM's either.

It's a shame, but becuase of this, I may not be able to provide everyone such detailed information anymore.

Mal.
