VAG-COM programming codes wanted

Hi,

I also built my own diagnostic adapter V2.2, and after overcoming various difficulties, it works great!

It's strange. It's always reported that there are problems with the T3, which delivers more than 1V on the C channel and then stops working. 'On my device, I'm even measuring 1.2...1.5 V, and that doesn't seem to significantly affect the operation.'

Here's an experience of mine. Older engine control units (ECUs), like my Marelli ECU, only work if I set the start baud rate to 9200. Everything else works with it.

Okay, here's the translation:

Now, my question:
Reading and clearing error codes is not a problem without instructions.
'But can I also write to the control units? Doesn't that require codes and specific numerical codes, and setting things up?' Where can I get them from?
The 'Official Factory Repair' manual from Bentley, which costs 99 euros, is a bit too expensive for me to experiment with the electronics.
'You won't find something like that on eBay either. And Erwin (siehe Fehlerdatenbank) is a bit too stressful for me.' You need a credit card for that.

If anyone has a tip for me, that would be great! Sure, no problem.

Otherwise, have fun scanning those cars!

Regards,
Florian.
