We've never come across any instances of damage that have been caused by our Miles Tracker.
Mechanics and garages often use devices that plug into a car's OBD-II socket that can do a whole range of different things to your car.
Our Miles Tracker mainly uses the socket for power, and reads engine codes, but won't change anything on the car. The sort of functions it performs are standard and won't affect your car's electronics.
Of course, if you're worried about anything in relation to your car's electronics, do let us know over live chat and we'll look into it for you.
