That part number pins it down — 8K1 820 043 AG Continental Climatronic from an Audi A4/A5/Q5 (B8/8K/8T platform), MCU is a Renesas V850-family 70F3633. So we're talking CP on the AC control head, not the cluster/gateway.

First, be clear on your actual goal, because the method differs:

  • Replacing the unit / donor from another car → the clean way is a full clone: read the complete internal flash + data flash from the original working module and write it into the donor. The car then sees the same identity and existing adaptation, so CP never has to be "removed." This only works if both boards are the same HW and the donor can be fully overwritten.
  • Genuine CP removal on one module → normally that's an online SVM/GeKo job through a dealer, or editing the CP status directly in the dump once you know the byte location for this software.

Your two photos showing two boards side by side suggest you're going the clone route, which is the most reliable for this Climatronic.

Before anyone can point you to the exact CP byte or confirm the clone flow, post:

  • Did Multiprog actually read the 70F3633 full internal memory? What total dump size did you get, and does it also give you the separate data-flash region?
  • Are both modules the same part/HW/SW index (8K1 820 043 AG, same Continental A2C number)?
  • Is this a clone into a donor, or CP removal to run this exact head in a different car?

If Multiprog can do a stable full read/write of that Renesas, the clone is straightforward; the CP-edit path needs the software version and a known map first.
