Below you can find a list of typical issues and how to solve them

Problem: When starting the “ABRITES Diagnostics for VAG” on the splash screen “Interface NOT found” is displayed.

Solution

• Please be sure that the USB interface drivers are installed properly. You can look at the device manager, the USB interface should appear as “USB Serial Port (COMxx)” where “xx” is the number of the port

• If the interface is recognized OK, then please try to unplug and plug it again into the USB slot and restart the “ABRITES Diagnostics for VAG”.

• If the interface is not recognized (the USB interface appears with a yellow exclamation mark in the device manager), then you can try to solve the issue by uninstalling and reinstalling the USB interface drivers (see sections “Installing USB interface drivers” and “Uninstalling USB interface drivers”).

• If there are bluetooth devices try to disable them

Problem: When starting the “ABRITES Diagnostics for VAG” “Interface not calibrated” is displayed.

Problem: The device connects under K-Line on a random basis.

Solution

• Try to increase/decrease the “Wakeup echo delay” timing parameter.

Problem: The connection with the device under K-Line is unstable.

Solution

Try to increase/decrease the “Inter byte time”, “Time between messages” and “Communication echo delay” parameters.

Problem: How to recognize whether the instrument cluster is A4 RB4 or A4 RB4 Crypto.

Solution

If the instrument is not crypt (this means it is RB4) the immobilizer number (14 ASCII symbols) is found at addresses 0x00, 0x100 and 0x200. If the immobilizer number is placed there, then the instrument is not crypted.

Solution

• Read the RB8 instrument EEPROM, and change the immobilizer status to 6.
