Fault code 00561

[Audi-Porsche Avant RS2]

Hello, now on my RS2 I have new original MAF, new lambda probe original from Bosch but I have check and the code is the correct code for the RS2, new original Audi fuel filter and also new original N75 and pop off valve, I have try also to change the original 3,8 BAR FPR for ADU engine with a 4 BAR FPR for ABY engine but I have always the knock problem when the overboost turn on for some second, than probably the knock sensor resolve the problem, I think that the car is poor in fuel because is very slowly for me and I 'm sure that I have less that 370 PS that I can have with the PKM chip that I have in my ECU, I have the impression that the car was faster with the original Motronic chip for 315 PS that now with the PKM chip for 370 PS, with the original chip I was the 00561 error too and also another error code that I don't remember but car run fine and without knock problem when overboost turn on. Which other parts can cause this problem? Fuel pumpe? Injectors? Air inlet temperature sender? Water temperature sender? Or what? My car is also without cat but also with original cat I have the same problem. Thanks a lot! Bye

Nothing? I really don't know which other parts can cause this problem. Where can I find the value that I must see if a check the lambda, maf, inlet air temperature sensor, water temperature sensor, ecc? Thanks a lot! Bye

had this code come back over the last week (ambient temp probably a factor), upgraded to wider banded ABA clips (previously Norma) on TB and IC/PP connections, error cleared, rerun no probs, changed back to older clips error came back, well worth a check/change, the clips I had on were less than a year old, I'm guessing the mechanism just slacks off over time, easy fix if it works for you..


usually takes a few days for clips to settle, always check back after a week when cold and see if they still tighten

from a while back now (forgot i had pics) intermittent 561 code can also be generated from this old favourite, split hose, unmetered air, (note the split is on the lower half of the turbo inlet), you'll never find it without taking the hose off and inspecting, visual inspection in place hose looks good and clamp tight.

crank breather hose also on its way out, dunno about it being a 561 error condition but it wouldn't help
