I bought this scanner for full access to the "coding and service" system for activating the hidden functions of the Volkswagen Polo car using the CarScanner Pro application via iPhone, but it is not possible to create a pair when connected via bluetooth, writes it is impossible to create a pair, somehow connected through the CarScanner application itself , but there is still no access to coding, which means the chip does not match the description. The functions are exactly the same as on the Chinese Deshman ELM. It's a shame it's a waste of money!
