Quick and dirty log pulled. Only pulled in 1st gear on a very local street, trying to not annoy the neighbors. I added lambda and tried to record multiple runs, so I think the log is a mess. As before, at part throttle, it doesn't trigger limp mode. The last pull definitely triggered it, but much higher up than I expect, now somewhere near 4k. What isn't clear to me is why it triggered- suddenly the actual fuel rail pressure and the lambda begin dropping, but that's before there's a spike in the nominal quantity. The ITT keeps rising, though- is that normal for there to be a lag? Looking at the timestamps it's less time than I expected, so I guess that's normal. I tried to use a steady throttle application to avoid creating transients.

Log #828882
Usually I wouldn't bother logging anything unless you're able to do it in 4th gear (even 3rd would be ok). The load just isn't there in 1st gear to get much meaningful data, and it happens very quickly. That said, obviously you want to fix that large gap between requested and actual rail pressure when you start pushing the pedal down. Also, don't worry about lambda until you're able to do fully floored 3rd/4th gear pulls.
I wouldn't jump to any conclusion about a hardware issue until you've gotten some updated files to try out, it's very easy to think you have an issue when it's actually in the tuning so just wait till you have new files.

As for the 2700bar rail sensor (stock CUAA sensor BTW), you don't need it at the moment and would only be an additional variable thrown into the troubleshooting process. It's not the "adaptation" for it, it's about knowing where the map lives in the ECU to change the linearization values. The stocker measures 2200bar at 5v, whereas the CUAA reads 2700bar at 5v. The only purpose that it serves as an upgrade, is to be able to push up the rail pressure thus injecting more fuel for the same injection duration.

The boost log looks a lot like the "symptom" I had when doing a bigger turbo. It was all tuning related, and mostly due to incorrect requested airflow. I'd be logging lambda as well, anything below 0.9-1.0 is going to take a toll on your oil over time.
The fuel pressure issue could very easily just be simple tuning adjustments needed vs hardware issue. If you log the regulator in addition to the high pressure sensor nominal and actual, you'll get the full picture of what it's trying to do.
Interesting point on the lambda, I started looking at that as I was out driving today (safety inspection and now plated down here). Under light or moderate acceleration (I did not floor it, was in rush hour traffic), lambda will go below .9. Most of the time, if it went below .8, that's when I would get limp mode. I'm pulling codes right now, and I'll drop them in. I must have gotten it four or five times, maybe more, trying to sneak up on that point looking for correlation. However... when lugging it in 5th at low speed, I got it down to a steady .8 without kicking limp mode.

What does a low lambda like that do to the oil? Do you mean, under full acceleration, or any time? That's just a different expression of the fuel/air ratio, correct? I'm dropping the entire autoscan below, if it needs to be trimmed just ask and I'll pull anything.

Something else to put a pin in: The battery died three days ago. It would not charge bove 4.5v, so I figured it was dead-dead. My new battery was too low on volts to power the car this afternoon, only showed 4.87v. I was a dips**t and left the VCDS cable plugged in for over 24h, but I don't think the hex cable itself draws that much. I'm wondering if I have something sucking power, and for now I'm going to pull the terminal when not driving. hate to treat it that way, but I can't take the chance of being dead after a 4 day trip.

I notice a code for the sat radio coming up repeatedly, 5F. Volts and everything on that looks normal but the antenna amps are 0. Why would that keep coming up? Could the head unit be staying powered, even though the screen is off and it gives the appearance of not being on? I wonder if there's a way to check current draw in vcds, but I doubt it.

Messy logs. I started with the rail pressure set, then added lambda (missed the comment in the post) and fuel regulation. I'm not sure what the relationship of everything is, but I can see that in some places there's a inflection point where "fuel pressure regulator: specified value rail pressure" goes up while "Fuel Pressure Regulation: 2" goes down in lockstep with "Fuel high presure sensor: actual value" and then tracks along with it. I can't see the trigger on here, but something leads to a big, ongoing drop in fuel pressure. Could it be that the pump isn't able to supply enough? I can't see that being the case, because at the end I did one final run in 3rd, from 3000 up to almost 5000, and it was at almost full throttle at the end without getting limp mode. I didn't pull a log for that, I might further on.

This is a graph of a pull in 3rd gear (I was tripping limp mode too easily in 4th):

Log #829303

In order, the seven different logs. All were from about 1500 to either limp mode or about 4000. Any idea which VCDS fields might be more useful? What will get the data needed to make this reliable enough to either get to full throttle or determine if there's a hardware issue?

You're guessing too much about possible issues with the car/hardware when it's likely all in the tune. Have you had any revisions yet, or are you logging all from the same file as before?
Lambda <0.8 should look like pitch black storm clouds coming from your tailpipe, all that extra soot over time will get into the oil and cause extra wear. Lambda of 1.0 = 14.5:1 AFR and is an ok target for full-pedal pulls, and 1.17 lambda is generally considered a good smoke-free target. Depends on the exact motor as well, I think mine at 1.0-1.05 is really light haze out the back.

Maybe start a dedicated thread for this or shoot me a message if you like.

20K service on my GSW:

Oil change isn't the most fun, but not horrible. Fuel filter replacement is dead easy. And what's with all the screws in the airbox? MKIVs have 2. I think this one has 10.

And they strip out so readily...

I used a 1/4" rachet. There are a lot of opportunities to make things too tight in the routine service and break things. Oil pan, fuel filter housing, airbox. Belly pan screws too, I guess. When putting the cap back on the oil filter I tightened it just enough (I hope!) to let the o-rings do their work.

I take the odd "25-5Nm" marking on the oil filter main cap to be 25Nm for the big boy, 5Nm for the junior cap.

I use that attachment that screws in to the oil canister drain plug. Works, but not perfectly. I almost always spill a little.

Not if you just use a hand screwdriver. But to @IndigoBlueWagon's point, who has the patience to do that with TEN of them?
(I always use my small M18 impact driver and yeah - a couple are stripped.)
That's why I love my M12 fuel 1/4 on number 1, it spins at a moderate speed but hits like a limp noodle. perfect for belly pans bolts and other stuff.

I'm in no rush

Not TDI related, but the Mk7 TSI is about to hit 120K about 400 miles away. All ready for its 3rd DSG service and oil change.

I started my mirror renovation project where I replaced a broken driver's side mirror on my 2015 Golf TDI SE held together with gaffer's tape. Bought one from a salvage yard and I have fitted it with carbon fiber caps and dynamic mirror blinkers.

don't get him going, before he knows it he'll be adding kessy to the rear door handles and AID cluster swaps.
