hiya everyone first time post and could do with digging into your wealth of knowledge, ( 2014 leon 2.0 tdi 184) my problem is i cant get the vag dpf app to work (free version i should add , im a tight yorkshireman) the app connects via bluetooth and the obd icon lights up but then it doesnt go any further ,car icon wont light up, not great with tech but this should be straight forward should mention im connecting through that useless peice of plastic called carista, even tried it with engine running any advice you can give me would be greatfully apreciated
