It works with the 95080 eprom for a Mercedes W369.?

• Read the 95080 dump with a suitable SPI programmer (e.g. UPA, Orange5, VVDI Prog, etc.).
• Use a tool that actually supports W639 95080 mileage calculation — for example Mileage Master, Dash Explorer, or NEC/Renesas-based cluster editors that handle SPI EEPROMs.
• If you want manual help, post the dump (or at least the relevant hex range) and confirm the exact cluster part number (A 639 xxx xx xx) — someone may be able to point you to the correct offset and encoding.

Hi,
I need to change the SSID of the dashboard A639 446 03 21 eprom 95080 KLM 53499 Mercedes W639 Vi...

1. Confirm the total dump size — the 95080 is 32Kbit = 4096 bytes (0x1000). If your dump has a different size, tell us what it is.
2. Post the dump in .bin or .hex format (not RAR), or paste the hex content here (at least offsets 0x000–0x0FF and 0x300–0x3FF) so we can search for the current SSID.
3. Which programmer are you using to ler/escrever program the 95080? (VVDI Prog, UPA, Orange5, TL866, or another?)

1. Read the complete dump from the replacement cluster's 95080.
2. Locate the current SSID of the donor cluster in the dump (search for the corresponding hex pattern).
3. Replace it with your EZS SSID: 5869C1148 — which in ASCII hex would be
   Code:

   35 38 36 39 43 31 31 34 38

4. Write the modified dump back to the 95080.
5. Install and test — the cluster should recognize the EZS and display the KLMs.

• Always back up the original dump before making any changes.
• In addition to the SSID, the donor cluster may have different mileage — at the moment it displays 0 km, which is normal for a cluster that is not communicating with the EZS. After correcting the SSID, the mileage stored in the cluster will appear (that of the donor cluster, not your car's).
• The DASH Calibration tool does not support this cluster/chip, as already mentioned in the previous post.
• More suitable tools for this work: VVDI MB + VVDI Prog, NEC Key Adaptor, or manual editing of the dump with a hex editor.

1. Confirm the target SSID — your EZS shows SSID 5869C1148. In 5-byte hex, this can be encoded in two ways. I need you to confirm: when you read the SSID with the diagnostic tool (Launch/Autel), does it display exactly 5869C1148 (9 hex characters)?
   
2. Read the SSID from the dead original cluster — if you still have the original cluster (the one that failed), ideally you should read its 95080 as well. This would confirm whether the SSID in that dump matches the EZS's 5869C1148, and we would know the exact format and offset.
   
3. Before editing — make a second backup copy of this dump.

• Can you read the EEPROM from the original cluster (the one that failed)? Even if the cluster does not work, if the 95080 chip is OK, the Autel XP400 Pro can still read it.
• Is the SSID 5869C1148 exactly 9 characters? Please confirm from the diagnostic photo (the photo is partially obscured by glare).

No, I don't have the original. Is there another solution?

                      2A 10 B9 11 DB 0B

• Opção A (nibble alto primeiro):
  Code:

  58 69 C1 14 80

• Opção B (com prefixo 0):
  Code:

  05 86 9C 11 48

Antes:  2A 10 B9 11 DB 0B
Depois: 58 69 C1 14 80 0B

1. Abre o dump num editor hex (HxD, por exemplo)
2. Vai ao offset 0x0274
3. Substitui 2A 10 B9 11 DB por 58 69 C1 14 80
4. Grava como novo ficheiro (não sobrescrevas o original!)
5. Escreve o dump modificado na 95080 com o Autel XP400 Pro
6. Monta o painel e testa

• Se o SSID ficar correcto → o painel vai comunicar com o EZS, os KLMs desaparecem e o odómetro mostra a quilometragem (a que estava guardada no painel doador)
• Se não funcionar → o formato pode ser a Opção B, nesse caso tenta substituir por 05 86 9C 11 48 nos mesmos offsets
