Need immo off

Your file looks like it's already been modified – the extensive 0xC3 padding throughout and the 0xFF block in the middle are typical of an immo-off or virgin file rather than an original read. The TSW V2.40 string confirms it's EDC15C4 firmware, but I can't verify whether this particular file is complete or compatible with your 2001 E46 330d without seeing an original read from your actual ECU.

For bench writing with your tools:

• MPPS16 or Kess V2 can handle EDC15C4 on bench (BDM connection required).
• The file size (512 KB) matches a full flash, so if this is the correct variant for your hardware, you'd write the entire bin.

Before writing, confirm your ECU's hardware and software numbers (usually on the label or readable via OBD). If this file didn't come from your ECU originally, there's a risk of mismatch. Do you have the original dump, or did this come from another source?
