2008 sprinter ecu

[chrono122]

Does anyone know if galletto2 can read flash for sprinter ecus 2007+ 3.0 diesels without opening it? k line or obd, I want to do more tunning but scared as hell to open them 3 died so far..... Not right away a few months later. Don't want to make holes either since it sits in the engine bay.

Or does anyone know if I can use anything else that could read/write these without busting it open? Vediamo, mpps etc.

Thanks in advance!
