WTF is "By"? Post is by who ?. Are you "BI"? Just generally figure There's no useful communication here for you either because folk will say "Bye Bye" if you can't at least provide some bare minimum of relevant information on your posts like WTF Tool you are using and current software level, make model , year of vehicles you tried so far. You already Confirmed no communication issue trying it on other vehicles of same makes, but it still communicates fine on every other make you tried it on? You still have a current update subscription and good high speed internet and You have created enough storage space on unit to delete corrupt Benz, Sprinter, App, plus other car apps you rarely use and redownloaded the Benz Sprinter App software over again and it still won't communicate with those makes?
If people need to ask all these questions then it just seems to just be random trolling rant or you're just lazy, not providing any relevant details and didn't try anything so far to figure out if it's the car, the software or the VCI on your own, to create a relevant post people will want to invest their time trying to help you out. This applies to everyone posting on here. I think Autel should actually require certain fields are filled out completely when creating a post including the poster's screen name, platform used , car app software version in use . Year, make , model of vehicle. What specific modules it don't communicate with , what you have tried so far to fix problem before getting other's help.
