Dreadful
If you have an AP200 then you obviously use MaxiAP200 which can read live data but to use the Sprinter service options you must download this (free once). Sadly this app can’t read the live data like MaxiAp200 can so regeneration feature can’t be used either because it says my water temp is below 60 degrees but maxiap200 is showing the correct data of 75 degrees. When manually selecting engine and transmission it gets stuck at 70%. I know this was a stab in the dark but if you have an icarsoft system (that hasn’t got soaked in the rain, like mine did) then please stick to that and don’t waste your money on this junk. Now I need to buy a new icarsoft and work out how to get a refund on this useless crap. Will avoid Autel in fuel tire if this is anything to go by.
