Hi
Guys 
Please help
I have a problem with Audi A4 B8, when I scan with Autel Maxysys, no fault , all ECU's are OK, but when I enter ESP module to scan ESP fault malfunction popping up on dashboard, but there is no any fault code when i enter fault codes section to clear,

when I drive the car and same time scanner is connected ESP/ABS computer to see live data, ABS system working correctly,  but when I remove scanner and drive ESP/ABS system not working correctly, and after stopping again connect to check if any faults are stored on ESP, but no fault, 

fuses, wire connection all are very good, checked, 


What might be problem? 
ESP ecu is faulty?

Have you had a problem similiar like this one with Audi? 
its like when scanner is connected to ESP module its making a ESP work correctly, once scanner is out. ESP / ABS system works faulty

Another interesting thing discovered now
While driving if your scanner is connected and scanning ESP module. all ok,
and you start scanning engine for example. and drive, same faulty is back, and you can not enter again into ESP module while car on drive

Similar thing happened to me on Skoda Octavia 2 with that scanner.
After I cleared errors with VCDS, everything went back to normal.
Hope this helps!
