When using VAG-COM with VAG models you have to select the “Turbo” button and the “UDS” button (this button is left from the “Turbo” button [But it isn’t always available on every car] ) after choosing the Value’s you like to log.

Left in the VAG-COM screen you can see the logging speed. This value should be at least 4.
If it isn’t you have to select less value’s and make a second log with the other value’s you would like to log.
