Complete useless scam. Nothing works. For example Opel Insignia 2010 - health report is not available, connection to parking sensors is not available, service functions doesn't work. you take old DS150 and everything works, but this app and dongle is useless. Money wasted.

Can't read transmission module on all Toyotas. Auto VIN also doesn't work on Toyotas you have to manually input VIN, year, make, engine type, which is very exhausting and time consuming. and now the app takes long to open and freezes, and cars like Citroen, Peugeot, Haval, Volvo, Range rover, Mahindra/Tata are totally unavailable and also system scan takes way too long especially on VW.

The Bluetooth device is great but the app lacks the ability to log data and export it to a .csv file for example. It works great with Car Scanner but Car Scanner does not read all PIDs at least on a 2011 Hyundai I30 1.6 CRDI. Can a logging option be added?
