Hi everyone, this is my first post 
.
I’m in charge of a 2015 DAF LF Road sweeper (family business), and I want to invest in a decent diagnostic tool.
I know Davy is the dogs ■■■■■■■■, but does anyone know of any cheap/generic/chinese diag tools that can get the job done?
I’ve had an engine light on all week and I don’t to take it into DAF 
, I have a mechanic mate who’s up for it
