Question:
Is it safe to write on OBD for this Mercedes-Benz CRD3.10 ECU using Foxflash?
Solution:
If need OBD, better use KESS V2 or KESS3.
KESS is better for MB CRD ECUs.
Better bench MB CRDxxx with foxflash.
If do it on bech, try it with 13.5 voltage, and the button on mfc cable let it on.
We read on bench every time without problem. Check conection, also power must to be connected on the bench box.
