On bench, I primarily use KTM Bench for Tricore without any issues, rather than KT200. However, for tasks that KESS or MPPS don't support via OBD or that KTAG doesn't support in BOOT mode, I use KT200, which works well. Just yesterday, I successfully worked Full system on Ducato 2017/2018 MJD 9DF without SGW via obd connector read/write eeprom and flash, and it performed flawlessly.
 

In my experience, kt200 has more success. 

I have not had any problems with my KT200.
