Mode under Address word 33:(VAG1551)







Mode 1 to 9 can be selected under address word 33.
- Individual measured values can be read out under mode 1. Mode 1 is not recommended for authorized Audi service centers, since the data can be obtained much more accurately under address word 01 function 04 or function 08.
- Mode 2 displays operating conditions, for which malfunctions are recognized.
- With mode 3 the DTC memory will be checked and with mode 4 the DTC memory will be erased.
