What's wrong? It should be okay. Or did I misread the target values?
I'm more concerned about the start of the injection.

@Golfmann:

The numerical values you read from display group 0 are dimensionless, meaning that the numerical value of 140 for the fuel temperature does not represent 140°C, but perhaps 43.57°C. Do you understand what I mean?
You would first need a table or a characteristic curve to be able to translate this "raw data" into standard units.
However, if you use the correct diagram for pump adjustment, then it doesn't matter whether it displays 140 (???), 43.57°C, or 795 apples.

@RalphViewing profile: Ralph:
I think you are right icon_redface.gif.
Purely from a logical perspective, the following connection arises:
Assuming a German engine has a clockwise rotation (when viewed from the clutch side), then the timing pulley on the crankshaft rotates counter-clockwise.
Similarly, the camshaft and the pump shaft then rotate counterclockwise.
If I rotate the pump shaft relative to the ESP wheel counter to the direction of rotation (i.e., clockwise), it results in an advance in timing, and vice versa.
You then need to rotate the pump housing in the direction of rotation of the impeller to achieve the same effect (early timing).

Thanks for the improvement!! We don't want our golfer to get even more misaligned.

Regards,
Alex.

Hello,

Assuming that a German engine has a clockwise rotation (clockwise, relative to the clutch side), then the timing pulley on the crankshaft rotates counter-clockwise.
Similarly, the camshaft and the pump shaft then rotate counterclockwise.


wrong again!
Clockwise: In the direction of rotation, as viewed from the side opposite to the power output. (DIN 73021)

@golfmann
Read Garth Brooks' post again; he wrote it correctly!

Best regards,

@donalexo

Okay, thanks for the tip. I was wondering how the engine manages to reach a diesel temperature of 140 degrees. Now it's clear to me. By the way, I'm using the diagram from 'Dieselschrauber.'
I'm going to adjust my fuel pump this Saturday afternoon. Let's see what happens. I also have a VAG Com for checking. And I'll mark the original setting. At least it's running now.

I'll get back to you.
