Pictures of my inlet ports....
Arthur, you said you have a document that states you can't publish what they say... I'm just a customer, as you claim you are, yet I don't have that document??
I agree with the comment about power loss over time. This is exactly what happened. You don't notice 0.5-1 horse power loss a week (yes, I lost power over a year!). I thought it was ok, and I just got used to the power (as I do in most cars). It's wasn't until the Dyno, and then ultimately the pinging that got my attention.
Again, the flaps were fine before. Long story short, the manifold was replaced due to one of the plastic arms breaking during one of the manifold removals (I think it was removed 4 times in total). The flaps have never been a cause of the power loss (expect when the manifold was put back on with a broken arm, but that caused an EPC and engine light). I hope that clears it up (for the enth time!)
Remember Audi Australia replaced my PCV to try to reduce the carbon buildup, thinking that may be the cause. Looking at the scope, I don't think it has helped, but the guys will remove the manifold again to check (hopefully next week?).
At saying all this, I was really disapointed initially with Audi, but now, I'm really impressed at how they are dealing with this. I can only recommend talking to your dealer, getting them to drive the car and if you can maybe compare it with a clean one. That will at least have them looking for a cause. It wont take too long for them to realise it's carbon (get them to send the air volume logs to Germany and I'm sure this will help).

We had a very similar debate a few years ago on here about how widespread the DRC problem was - some insisted it was "every car" that was affected, others that it was "only a few".Sims wrote:I recall you mentioning DRC was hardly an issue in the US, but it is here in the UK so maybe there are differences.
The threads still exist on here - check the numbers, out of approximately 3000 RS4s in the UK we only have evidence for about 100 (the exact numbers are unimportant, the scale is what I'm commenting on) having DRC failures. So that's 1 in 30 - and Audi UK HAVE stepped up to the mark and extended the warranty to 5 years/75,000 miles (although there is some dispute whether that's a goodwill gesture or not - the letter I have from Jeremy Hicks makes no mention of goodwill).
It took a long time before the DRC debate finally agreed that DRC is NOT an "every car" issue, but tempers were longer and minds more open in that debate than in this one - which makes me think this debate has become utterly pointless since there are too many minds stuck on opinions and unwilling to look at facts and science.
all documents by any corporation have a disclaimer...this is correspondence/communication between myself and them...
that is how it was offered, not that I would post it in the public domain...
have you corresponded in writing with Audi AG (and US) asking specific questions? by ensuring I will not blab all over the internet wouldn't that possibly allow them to be more candid?
I do not speak for Audi, and anyone who tells you they do is lying, unless of course it is directly from them via email, regular mail or on their official website...not thru some anonymous 3rd party on a forum....that is ridiculous...
there is no way in heaven or hell deposits cause a 90-100 HP power loss in a lifetime, let alone months...
your power loss, as was obvious to me, and many others, and was absolutely the intake flaps/vacuum leak, many others have suffered the exact same curve, in fact there is an SIB out on it...
obviously you're not going to convince me, and vice versa, so let the reader decide

Absolutely in agreement....you must be pretty gullable to think this "qisha" dude works for Audi, unless he's the mail man ! LOLArthurPE wrote:

isn't that a bit silly?
they all have deposits
deposits don't cost power due to Q loss or timing <beep>...

Qisha has been posting on the RS4, R8, RS5, TTRS well before the information became available generally. And is very well respected on other forums, and has more than just a handful of followers over the 7 years.
If he is the mail man, it's probably for Reil.

Others in the meantime claim Audi said this & that, did this and that, but then hide under confidentiality so....

Here's one thread on this forum:

123 people. You say numbers are not important, but already we have 4% instead of the 3 you are offeriing, and the less than 1% offered by your mate. But never mind.
Now, do you believe every one of those 3000 owners is on this forum, and would post if they had a DRC problem. Get real PD, support facts & science, not people. Speak to a few Audi dealers.
You say Audi stepped up to the mark - that's nonsense, they had no choice. In fact I maintain, they should offer all RS4 owners an option to switch to coil overs as a final settlement or otherwise the design fault has not been remedied.
If we have a big issue with DRC, and I absolutely 100% believe that, how come the US does not suffer such fate according to Art - he too is an engineer and so would not make inaccurate statements, would he? Is their suspension different, are their roads better (that can be

On carbon, you say the debate has become pointless. I say the debate is healthy. Are you 100% convinced that the carbon does not affect more than 2% on power or fuel consumption, and will not be a long term issue?. A Yes or No answer will suffice.
As you say, let's look at facts & science.

Yet you keep claiming a cosy relationship with them, getting candid explanations, being told Qisha does not work for them - your information and assertions are worth nothing for you even further away in the food chain.ArthurPE wrote:all documents by any corporation have a disclaimer...this is correspondence/communication between myself and them...

On fine form this morning aren't you Sims? The crystal meth not worn off yet? Out to gun everyone down that doesn't comply with your line of thought.
As said previously you have a canny knack of manipulating comments and data to suit your own version of events, get yourself into politics and give us a break.

quisha does not work for Audi
he does not represent Audi
that stuff you post is NOT from Audi
if he says the rings are in the head, he IS less believable

not a representative example, most owners are not on forums
and only people will 'issues' tend to post/complain
less than 1% of all cars have been affected so far
but even using your 3-4%, that is far less than EVERY car...
deposits
normal
no mpg impact
no timing impact
no mixture impact
<2% power impact, worse case

You really ought to read posts properly before hurling abuse and accusations, mostly attempting to defend some cause in a misguided belief.
