Bosch part number: gasket + screw for cover, quantity adjustment mechanism?

Hello,
"This coming weekend, I'd like to verschandeln my volume control knob because it's been acting up. My initial plan is just to remove the cover of the volume control and verschandeln it that way. Since I assume the seal shouldn't be reused anyway, and it doesn't cost much, I want to replace it. Also, I'd like to replace the triangular screw with one of the other Torx screws."

Could someone please tell me the Bosch part number for the gasket or screw? I'd like to know the number beforehand so that the Bosch service center doesn't have to search for it for too long.

Greetings.

So, for the seals, there's a repair kit available from Bosch that includes various or all of the seals for the specific pump and costs around €6.50. You just need to tell them which pump it's for, for example, the VP 37.

My BOSCH always finds what it's looking for quickly.

They're sending me an exploded diagram with numbers indicating the parts, like 1, 2 (not part numbers).
I'll tell them I need the numbers 4.174 and 23, and then I'll get them.

It seems to depend heavily on the individual using the BOSCH computer as to whether they want to and are able to do it.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hello everyone,
ich war gestern bei meinem Boschfuzzi. Eine halbe Stunde hat der Bosch-mensch gebraucht um die Teilenummern rauszufinden mit dem Ergebniss das ich für einen Satz Dichtungen und eine Schraube 14,64€ latzen musste. Was für eine Abzocke!!!

Let's hope that after the signal box is cleaned, the jolting will stop.

Greetings.

PS: Is the entire fuel injection system (including the circuit board) exposed to diesel? I mean, does diesel immediately come into contact when you remove the cover, or is it only located underneath the circuit board?

all in diesel

'...Well, 14.64€ is still manageable...there are worse things...these sentences were already sold and bought privately on eBay for 30€...'
