As I understand it, he's talking about everything you could potentially try until you resolve the problem.
Starter, battery, VP37 engine, fuel injectors, and then there's the issue with the compression.

Exactly like that... Unfortunately.

It's not a problem to change it via a chip modification, but I haven't had any cars with a 'start problem' yet.
However, it works perfectly well with plant-based diesel fuels.

Is there a chance to achieve this without reprogramming the chip, perhaps through adjustment channels? Or is it unavoidable? If so, are there any known offsets in the memory where this can be influenced?

not that I know. Otherwise, I wouldn't need to tinker with the chip, but I would just briefly connect a VAG-COM .

The 'offsets,' as you call them, are, of course, familiar to me; otherwise, I wouldn't be offering this service. Fortunately, they are different in almost every engine control unit/software version .

Best regards, Rainer.

Things like the battery can be easily tested. Just try bridging it and starting the other car. If it starts better, you've found your problem.
