We first checked the hardware of MB STAR C4/C5 and found that the hardware works normally. The problem should be in the software section.

It turns out that the customer has set the hardware mode error to C6 mode.

If you set the wrong hardware mode, there will be some Mercedes-Benz models that cannot be diagnosed or some features that cannot be used.
