.. I just happily signed up here (and apparently passed the test ).
and then to read that this is about turbo diesel engines.
I was just hoping to find out if anyone has any information about the ESP (Electronic Stability Program) settings for the AAB engine (VW 2.4-liter naturally aspirated diesel), specifically regarding idle speed and the temperature-dependent behavior of the idle speed.
Well, maybe there's at least a link somewhere...
The problem has been solved.
The Bosch diesel injection pump specialist 'twisted' a spring during assembly, after sealing the control shaft. This made it impossible to adjust the idle speed and caused a slight 'sawing' noise. Now everything is okay, and it idles smoothly at 810 rpm instead of shaking like before at 700 rpm.
