Sometimes meaning you are wrong. We are talinkg about very old firmware 1.20.020 and today we are at 1.20.41 or 1.20.42. How do you expect that old firmware to work ok on new programs with another structure?
Do you think VAG and Softing are fools and did upgrade of firmwares just to play?

Shit bluetooth, want it to work ok, use old program not new one. All rest is just smoke

Want to use all programs new and old find one AMB2300 good module and use it or a good vas head.

Seems like you are wrong on this one... I own two interfaces, one with the crappy bluetooth module and a new interface with everything on it. As a matter of fact, the old module with crappy bluetooth module is functional on 4.2.3 when using the older PDU API file trick (don't know which version it was anymore). I tried this 'crappy' module with ODIS 4.2.3 on many cars, even newer ones. I'm not only talking about reading for faults, but also GFF, adaptations, offline interactive functions, reading measurement blocks, running test programs, flashing (in new ODIS-E) and so on... I never noticed anything that wasn't working on ODIS-S 4.2.3 with that 'crappy' module. BTW I never use the prehistoric technology called bluetooth anyway. So I'm sure for some people this could be a solution. Is it a good solution? Of course not. That's why I bought the new interface. But you can never say it's a good solution to use clone devices anyway.
