To help you (or anyone else who might have the file) identify the correct original TCU flash for your BMW E61 530xd LCI, we need a few more details:

• Which exact TCU is fitted — 6HP26TÜ or 6HP32TÜ? (The 530xd LCI typically has the 6HP26, but please confirm.)
• TCU hardware number (HW) and software number (SW) — you can read these via ISTA/D, Tool32, or from the TCU label itself.
• Converter code (Wandlerkennung) if available.
• How was the TCU read — OBD (K-DCAN / ENET), bench, or BDM/boot? Full read or partial (just the calibration area)?
• What tool are you using for read/write (e.g., Ktag, CMD, ByteShooter, ISTA/P, etc.)?

With the HW/SW identifiers, someone here can confirm whether they have a matching original file or point you to the correct one. Without those numbers it's impossible to guarantee compatibility — even within the same model, different production dates can have different calibrations.
