Notes on display zone 4:

For a defined fault finding the Oxygen Sensor (O2S) control is switched off when selecting display group 99 under "04-Basic setting" or switched on under "08-Read measured value block". When the function "04-Basic setting" is exited the Oxygen Sensor (O2S) control is automatically active again.
It is possible to switch between the function "04 -Basic setting" and the function "08 -Read measured value block" by pressing the buttons 4 and 8 on VAG 1551/1552.
