In my opinion C4 is the superior interface, clone or OEM.  Better to just use C4.  I don't know how good it is actually on DOIP, but there is information about how to make it work on those vehicles.

I've used real C4/C5/C6, C4 seems faster, and C5/C6 absolutely have issues on older cars.  I've seen situations where dealer says they need to replace a module because of no communication, but C4 communicates fine 100%, C6 problem.

P.S. Sorry, I know this wasn't your question.  Forum often considers VXDiag/Allscanner as "Allscammer".  I disagree a little about that opinion, and think some of the work they do is quite clever, but your better buying a clone from somewhere else, because VXDiag interfaces are often limited by software licensing etc, and while its a pretty easy thing to bypass, why buy from a company that puts that extra layer which requires you to give more money, for a product that is not even as good as other clone options that have no time limit.

How about eCom device's Softing?
