If I code an A4 RNS-E for an A3 but don't have an A3, will I be able to code it back to A4 or A6? Or is it like the phone interface where you can't tlk to it anymore if you code it for CAN only but don't have a CAN car like the A3 or B7?

I'm trying to understand how the diagnostics over CAN works in the A3 compared to diagnostics over k-line in the B6 and C5. If I would code my A4 RNS-E for an A3, would I still be able to talk to it via k-line?

Thanks,
Dirk

I'm pretty sure you can do so, as I talk to A3 mdels on my test bench over K-line
