ODIS + VAS 5054A, What’s possible? (Coding)

car diagnostic tool

Hi guys,

Is coding possible with ODIS + VAS 5054A clone?
I wanna change something (one or another bit) on an Audi a6 4g on the MMI

Replied by fellows at mhhauto.com:

Yes it is. But not every control unit / software is shown as textcoding. Some are not translated and you can only see them in raw bit coding (binary / hex). So yes, of course you can do coding, with ODIS-E and ODIS-S. Where I suggest to use ODIS-E.

With ODIS-E you have a slightly higher chance that coding schemes are implemented as text, than you have with ODIS-S. Whilst ODIS-S supports Guided Function where you just tell him what to do and it sets adaptation channels and/or codings for you (so actually in the end you don’t know what it did).

If you really know which bit you wanna change it doesnt matter what you use. But in case you wanna change things manually I think you should better go for VCDS. It has a lot of coding schemes, I’d say more then there are open as text in ODIS-E.

In the end it is all just a matter of what you need or wanna do.
