My only suggestion is to look through the FR to find under what conditions that error condition is set, and log for those conditions.
I will dig through the FR again (time permitting) and try to give you some pointers.
Alternately, compare the two files (NEF vs working mod) and look at each change and see what might cause it.
You do have quite a bit of overshoot, so you could be hitting DLULS. Pull a bit of IMX and try to get the overshoot under control.
What do you mean by "FR" I do not quite understand you.
The error as I have already said appears arbitrary, mainly on 4-5 gears with low engine speed and up to 3000-3500 rpm.
At this time, when I go with VCDS, I observe the increase in pressure up to 2400-2450 milibar in the 115 group.
The error manifests itself - you press on the gas and the car gets into an accident, releases the gas and immediately presses - the accident disappears
Now I have a new engine from Japan from Audi Allroad with a mileage of 70 thousand kilometers, the old engine was APB (the one with which I bought the car in the USA)
It had the same mistake, but I bought a new engine completely assembled with turbines and sensors, and the same thing on it ((
From the old motor only remains:
Clutch RS4 (Flywheel, basket and disk)
Engine wiring
ECU (with firmware)
Air filter (it was almost new)
Spark plug
Maf (I have 5 of them)
Exhaust RS4 B5
Lambda probes (I bought them new bosch)
Spider ventilation system for crankcase gases behind the engine and Valve of the sentiment system that is inserted into the Y-pipe
