Nyet, if you're in here, should I be posting this in the 5120 hack thread, or just PM tao until we get this resolved and then update the 5120 thread? I don't use forums much and I don't want to cause clutter.

this is most definitely not clutter. keep on.

I have done basically no analysis of this log other than glancing at the laptop while logging.  While doing so, I noticed a bunch of "drop outs" of data in the log while driving over bumps and when the powertrain loaded the engine mounts.  I saw a bunch of really bizarre knock retard, sometimes indicating knock during engine braking or return to idle while turning, stuff that doesn't make sense. 

I have a purple trace for lamfawkr in visualme7logger and I know I saw that going off the bottom of the screen over bumps.

I would never have known there was a problem without the laptop hooked up, the car drives fine.

rl_w (not rl, lesson learned) is still doing it's own thing.  Charge pressure, similarly, is following a profile I'd expect from a fixed WGDC.  I know PRJ mentioned you could blow the wastegate open on these K04-001's real easy, and it's making 25psi according to the boost gauge...maybe I'm just asking for too much.  I have a lot to think about.

I'll have a drink and pick up where I left off tomorrow.  Thank you all for your help and support.

Hi. I saw the problem with bts when i left stock TABGBTS. I disabled BTS but on the idle i saw a very rich afr, aproximatly 11.0-11.8. I changed the fuel pump, but without any changes. I will change the fuel pressure regulator to see what happen, because from the software nobody must make this afr request.
I saw the problem with vvt to from time to time, but i change it and again nothing modified. I have this error intermitent witch can affect the idle rev:
16396 - Bank 1: Camshaft A (Intake)
            P0012 - 35-10 - Advance Setpoint not Reached (Over-Retarded) - Intermittent.

check VCDS MB093 and report findings

Hi Rogerius.
From 2 days after i changed the spring from inside of vvt and the selenoid of vvt, the error doesn't appear.
I made a picture with block 90/91/83 (92 is not available) and i have when coolant temp is 75degree an idle adjustement -3kw (like in attached picture) and -1kw when coolant temp is 90-85 degree.
I specify here i have a DSG DQ250 mounted on the car. I tried 3 different file , 032hf(from automatic car) , 018H and 032HS, nothing happen, all make the same bad idle rev from time to time, only 032HF (from automatic) made the works , saw i think is not a torque intervention problem.

After another 2 days error come back.
Made a DPUPS stock not devided and the idle rev is much better, but the car feel without power in low rpm before 3500-4000 and the boost is made too slow, after this the boost is made.
Strange things with this 5120.

Dude, that's so cool!  I had no idea a DSG bolts to a 1.8T, that's a very interesting project.  I just had a look at the self study program for that gearbox, I know nothing about these. 

What's the mass of the DSG clutch/flywheel like in comparison to like a flex plate and torque converter or a typical dual mass flywheel and clutch? Were 1.8Ts ever offered with this transmission from VW/Audi?  I imagine a DSG behaves differently enough to a torque converter automatic during transient load/rpm fluctuations that maybe it's contributing to your problem?  I figure it's a question worth asking, I have no clue.

You should make a post in the project cars section, I'd love to follow your build, tao. 

My car generally just acts weird around idle when load changes.  It sounds like a KFMIOP/KFMIRL problem based on research I've done here.  I've read plenty of explanations of how those maps relate here but it's not clicking for me. I just need to find the time to bash my head against the FR until it does.

Mine 'lopes' in a periodic fashion when the AC is on, or when creeping forward by slipping the clutch.  I know the ECU is cracking the throttle because I can see fluctuations in manifold vacuum on the boost gauge, and I know the timing is fluctuating a lot.  It actually will start knocking at idle if the weather is hot enough or sitting in a lot of traffic (!).

I hope I have time to get to this before the season is over for me, once they salt the roads I park my Golf until spring.

My car works ok one year with dsg without that problem with idle rev. Now i have some issues/ problem witch can cause the all shits (cut throttle and idle rev)
First i have the camshaft overretards error, even if i changed the solenoid and spring , but it is intermitent , i will see when i have time to buy a new vvt and change it.
Second maybe my dsg clutch is over, even if i don't have error about them. I had only once gew weeks ago about maximum pressure exeed. If they are gone maybe when the car make power the throttle is cut because the clutch sleept.
I want to change the fuel pressire regulator maybe there is other cause at idle rev , because when goes to idle the afr goes very rich 11.2:1 and all my fuel maps are ok and request higher than 11.8:1 amd at idle bts is not active , temp is rised and is not touched to activate it. I don;t know from where this afr goes too rich and like i said i will try to change fpr. I found a topic somewhere where somebody wrote if clutch are gone in dsg can make this shit with idle. I ried to rise pressure in dsg but nothing happen.
And the last thing what i saw in my log , i have actual boost higher than boost desire  but load specified is higher than load actual , but load request is lower than load actual.....maybe must touch KFUR, or kisrm/kvlad......BUT again i tell, my car works ok 1 year, 10000km with this file and dsg and all hardware without other modifications. This is strange.

About yours questions:
-dsg fly is lower than dual mass of manual transmission
-dsg gearbox is heavy, somewhere 90kg so.....
