Question:
For Dacia Duster with EMS3155 ecu, no problem to read write via flex full obd ?
Here is the clue.
Just read a normal obd protocol.
For full obd, flex patch during ~45min
Full obd, first time patch is long maybe 45 mins to 1hr but after that is quick
Be careful if the car has the keyless system, if during reading or writing via OBD the dashboard turns off the control unit could remain in PROGRAMMING MODE even in bench mode it still remains in PROGRAMMING MODE, and it is not easy to reset it afterwards
Keyless in Renault/dacia is pain in the ass.
