I later phoned the hotline and let me explain exactly why this particular error of VAG CAM bus systems can not be read with the OBD2 Tester Launch Creader V. Such. As parking sensor or tank ventilation were not recognized. For the following error (oxygen sensor defect) but were recognized for it, and this is true also with the info about the Hotine and later Original VAG tester that emission-related fault and can be viewed with ODB devices and matches.
This is another mistake that have nothing to do with the exhaust system or engine management. As I said that these errors only work with the VAG bus system together and not with OBD 2, and the errors are stored somewhere else where the OBD 2 device can not access it.
Very good I liked the OBD2 tester Creader V Launch of that you can not always take a list like the other OBD devices or consult the Internet has what exactly is the error. Since the error sebst directly from the error code in the device in a brief description (big display - Matrix DOT) can be viewed, and the whole works without battery because it is powered through the connector to the board voltage.
Conclusion:
Thanks to the hotline for the declaration, unfortunately I had to return the unit back as it as already explained, a better solution with VAG bus systems are also recognizes the error that the device unfortunately can not display.
