Questions about this file
Is this original file compatible with my Scania R124?
Compare the hardware number (20426) and the software number (1071) with the identification your tool reads from the ECU. The software number must match; a different hardware revision usually means a different file. Continental/Siemens EMS S6 and EMS S8 controllers (Scania) are identified by a 7-digit hardware number and a 7-digit software number read by the tool or shown in SDP3.
What exactly do I receive when I buy the Motorola EMS S6 DC1203 original for €25?
