Не работает

Не работает в России. Зря отданные деньги за кодер. За несколько месяцев разработчик не предпринял никаких решений для исправления ситуации.

Работает с разными марками авто.

Очень удобное приложение

Это устройство Dfirst 201 BT (в народе «китайский свисток») подключается к машине и через
приложение в телефоне. Он объединяет в себе как базовую диагностику (чтение и
очистка ошибок), так и продвинутые возможности кодирования (одним кликом).
Например: отключить «СТАРТ-СТОП», русифицировать приборную панель и
др.50 функций. Интегрирована удобная SFD разблокировка; Привязка АКБ при
замене; Проверка всех блоков в системе по реальному пробегу в км.
