Update of how you now call me a mechanic not a technician now. I'm not one for swaping  parts without verifing but This car is my exception! I just swapped a brand new hpfp with low pressure sensor and high pressure sensor and now change.
So
o2 sensor
lpfp
hpfp/follower and check lobe, no damage
pcv whole system including check valve
ecu swapped out just to say I did
are all replaced!
I smoked tested the car, applied pressure to the system, checked every check valve, high pressure follows spec. Low pressure follows spec. all live data adds up, iat, coolant temp, calculated egt ect. No leaks, no kinks in the fuel lines. I called and made sure the parts were oem part numbers matching my vin as in 08 they changed some things on my engine.

Shit, this only leave fuel injectors and the fuel pump module, or this rear main seal
which I'm doubting the rear main seal because it would effect my idle trims= 2% at the moment. Plus I sprayed brake cleaner/map gas and it didn't seam to cause anything.

I'm thinking everything through!
only concerns I have is block 93 shows +9 and 94 shows 26, I don't know off the top of my head what these should be. I know on an rs6 you want block 93 showing 0.

So, what shall my next move be?

WAIT, 01011001 Lee or whatever your name is, you say simple fix, I agree. The difference between you and I
is that I am not sure whats wrong with the car, you on the other hand seem to be. So what is it, please just
name one part that has failed and is his problem. Since somehow my experience has come in to question I would
like to start by saying my first year with vw was 1998, before that I worked at a euro shop and a dodge dealer, i stayed
with vw till 2008 when I opened my own shop, since then I have been doing this for myself own my own.

Now I will continue to try and help this man, and you can do whatever you want...

Grease monkey or whatever you call me I still haven't given up. Actually every part was a well educated guess. It wasn't just swap this swap that. If data lines up it lines up. You explain how you would tackle this problem? This isn't a pissing contest. This is information to help people and help me. I'm not one to ask for help answers when it comes to fixing cars. This one just has me whipped.

Quick question for the Audi pros, when you give the car gas, and pedal position does the crank case/ oil pan go deeper into a vaccum?
In my reading this isn't the case. So this is why my theoretical thinking says rear main seal is fine. Also the fact I idle perfectly with once again 2% trim. Now if you guys are so educated on Audi's which I believe you guys are. Why hasn't this been solved with the very detailed info I've given?

Ok . After driving 5 miles or so i need readings from MVB 32 , 93 , 106 , 15 and 115  from Vag-com . DO NOT  erase the fault code before you look at the MVB ( MESSURED VALUE  BLOCKS ). 

BY ERASING the DTC ( fault codes ) you will reset all learned values ( fuel trims , boost learning curves , cam shaft crankshaft corralation correction  and many others ) . I am payed a lot of money every day for my diagnostic skills with Audi and VW  .  After you get screen shots of the MVB I REQUESTED i will be able to tell you what is wrong .

Dear, gman86

What the hell is a "  transmission>block gasket "  HuhHuh There is not one engine in a car out there that has a air tight seal between the transmission and the engine . What in gods name are you talking about ? If you can shown a gasket or seal that seals air off from transmission to engine in any 2.0T engine and stops atmospheric air  I will eat my word but this all so comes from a family ( my father ) that has owned a transmission shop for the past 52 years . I am sorry to say this mate but you dont have a clue what you are talking about .


Lee

Transmission gasket / block spacer / starter indexer, whatever you call it. It's not airtight but it's another obstacle.

You seem intent on proving that nobody has a clue, and you do. I've probably forgot more about MED9 than you'll ever know.

You're also a dick.

How have I shown that? The only thing demonstrated on here is that you're a dick who spends his life "replacing rear seals". You've not offered any "tuning" advice, just mechanical advice. You type like a fucking spastic as well, so retain your "silly little man" comments for yourself.

You know fuck all about tuning yet come in here with your preschool style of writing and slate other folk whom you have zero knowledge of their background or knowledge. Because someone disagrees with you, you say they are "a silly little man" and "don't have a clue"

I have FAR more experience of this engine and management system than your amateur spanner monkey paws will ever dream to see. Being a cunt doesn't make you useful, it makes you a cunt.

anyone else stop to think that since nothing else has fixed the car up to this point, that maybe he is actually right?

unless you want to keep bickering like school girls. by all means, continue on. i find it quite entertaining.

As far as I know we are waiting for the OP to supply the info that has be asked for so we can
all learn what is wrong with the car. I have decided to reserve anymore shit talking until after
the outcome. If its the rear main, it is what it is I was wrong but again considering idle trims
are what they are I doubt it.

The car has ran so many different software versions, chances are MAF scaling is off. We need to wait til the car is running again with the correct, factory, software and then diagnose.
