Hi, 


please, help me to solve my problem on MB Sprinter 2019 2.2DCI with ECU CRD3P.C0.
I wrote to the ECU mod file and when I put the ECU back to the car I can do only one start. Second start and other is not possible and in ECU is DTC p3102bc - memory int CVN. 
When I put original file back then car does not have any problem. 

I found some people who have the same problem but never see the solution.

could anyone help me? Where is the problem? 

thanks

I use original fgtech galletto tool and I made read and write in boot mode on the table.

problem solved by support fgtechnolgy.

After write via bootmode with patch ECU (for OBD writing) has problem with checksum. after OBD write all is OK and car works like a charm!

thanks to all
