Does anyone happen to know if Audi nozzles and VW nozzles are compatible, meaning interchangeable?
I have a vague recollection that Audi pistons have a different combustion chamber geometry, which might mean the injectors also have a slightly different spray pattern.
Can anyone confirm this, or perhaps even deny it?

Thank you for the link.
I'm still not understanding things clearly regarding my question.

The spray angle (spray pattern) can be, for example, 150° or 142°. As long as the nozzle holder combination is not installed incorrectly, there should be no problems.
