Hello together! In some Freds you could read that some of you have an OBD2 plug in the car to read out vehicle data via the app. E.g. water and oil temperature, regeneration cycle etc., But of course also to read out the error memory. I would like to add something like that. After a bit of research in the net I came across Carly or Pace. But there are also independent plugs, which then work with some app. At Carly and Bimmerlink have read that a lot can be done especially with BMW and VAG. What do you use this kind of data? Which live data can be displayed at Volvo and can be made with it also settings that you could not do otherwise? Thank you for your tips and recommendations! VG, Timo
