Only the 997TT and the Carreras get it, as well as the Caymans/Boxsters and Cayennes, but NO GT2/3 engine has DI as of yet.

FWIW.
DI is the future and the technology is no doubt getting better but that doesn't help existing owners.
it ~ the same as the RS4 (and just about every other car 200F/93C)
hot oil would increase the issue, more vapor, etc.
not help it
cooler thicker oil would help
In other words, you have no answer. Ducking and diving as usual.ArthurPE wrote:I have, through other channelsSims wrote: How about helping all the other people on here for this is your main Audi forum, surely they would be interested in this important development.
I spoke to more than a few, and PM'ed with many more...
in fact I've spoken to people who have this special diagnostic servcie by Audi...
but you are outside the circle of trust

that's my wag, leaky valve guides/seals...
and the effectiveness of the seal has several factors, imo
break-in procedure, higher speed, better finished/polished surface, plus frequent changes for the first 10k miles
engine temp, the warmer, the more expansion, the tighter the sael...perhpas the reason for the RS5 revised +10C operating temp (if true)
oil cleanliness (particles willcause small gaps, ie, leaks) and oil weight, thick = less seepage...
that is very interesting info, thanks
He has an opinion, and you have yours - freedom of speech. I am sure he does not need your advice. And you are sensationilising again.ArthurPE wrote:...friendly word of advice, be careful what you post, especially when rendering a professional engineering opinion regarding a product liability assertion...that could affect tens of thousands of engines...
I have more faith in Audi's answers anyways, thanks2manytoys wrote:Not really interested in answering your questions Arthur. If there was split milk in front of the fridge you'd say a cow did it. How could a milk bottle jump out of the fridge and spill itself (you add lol on the end to imply others are dumb too).
ArthurPE wrote:no
and hotter oil will be thinner and leak MORE, not less...
although I do believe the deposits are valve guide/seal seepage...
as I have said numerous times
I am firmly convinced it is NOT blow-by
NO...

'if true'
I asked, it's not true...
after thinking about it, the block temp (and valve train components) are not really controlled by oil temp, as much as the water jacket temp...
either way, thicker oil will leak less...
I was trying to determine if the oil was 10C hotter, why would they do so...
it isn't, so it's moot
You claim "not according to Audi" but yet again don't really know do you. Audi does not need you to defend them, in fact you are harming them - they will step up to the plate when they have to as they have done before.Users browsing this forum: Google [Bot] and 118 guests
