I actually described the cleaning process in the first post of my cleaning thread.
for 3 EUR, I went inside the washing machine and used a pressure washer (be careful, it spits back

).
Then I spent two days driving around with a broken breast (likely referring to a car).
The grime cannot be removed simply by the presence of diesel; it won't dissolve or wash away. You need to use your fingers and brushes to work on it.

Do you have a new throttle body installed? The black part with the four intake openings?
It absolutely has to be replaced.
Is everything alright? / Is everything okay? / Is everything sealed?
You shouldn't rely solely on the driving feel; do you have any data showing the Z-axis values before and after closing [something]?
Okay, please provide the German text you would like me to translate into English. I will only provide the translation.
