Peugeot 307 Siemens SID801 5WS40030B-T original software. Some tools use line swapping and some tools program different zones in the software section before the map area. This software was made using MPPS. If using other tools we recommend that you import the project over the top of your original software in WinOLS and then reset any software zones which are different. All checksums have been fixed in this software, of course if you change anything the checksum will need to be calculated again.
