How to choose a good VAG diagnostic tool for coding

Collected from some forums which share the info about VAS diagnostic tool. After checking the function and feature about the VAG diagnostic interface. What to do next?

1)      Quality depends on the inner board

VAS6154 china clone interface comes with inner boards updated & improved a lot.
There are two 6154 versions: one with wireless network & USB modules and the other without wireless network module (the wireless network module can be retrofitted at any time provided national regulations permit).

2)     VAS-PC vs ODIS
You can't to use any older Odis version for GEKO, you need latest 4.0.0 and also if you are erwin user you need to have and to replace the dms.trust.keystore with the new supported one..........
If you are erwin user all this info you can read when you logon with your acount......
But of course you can try to use the older Odis 3.0.3 with the new keystore file........

3)       ODIS or VCDS or VCP: which best?

ODIS is OEM, so it fully supports every VAG model, and it’s best for flashing

but it’s slow and you need online connection for being able to do a lot of things

Vas 6154 head should run faster with ODIS than 5054A

VCDS is super fast, best to read DTC’s and do basic stuff (diagnosis) and some simple coding

but it doesn’t work well with new MQB platform.

VCP is little bit a mix of those, best for parametring and quick eeprom read and DTC fast read

every feature (coding & programming) is done offline

Doesn’t need engineer codes for coding or programming

work very well with MQB
