Help Needed: IMMO Off for Simos 9.1 (Polo 9N) Due to Cluster Swap Issues

[tobir91]

Hey everyone,
I’ve been struggling with a cluster (tachometer) swap on my Polo 9N, which uses a Simos 9.1 ECU. After multiple attempts to get everything working correctly, I’m looking for a reliable IMMO off solution.
I’ve attached my ECU read file in the hope that someone here can help me remove or disable the immobilizer. The cluster replacement has caused a lot of headaches, and I’d really appreciate any advice or assistance on how to make this work smoothly.
If anyone has experience with Simos 9.1 or has done something similar on a Polo 9N before, please let me know. Any recommendations, software tools, or even direct file modifications to get IMMO off would be incredibly helpful.
Thanks in advance for your support!


Best regards

Thanks

read pin from old cluster and replacement adapt with VCDS match keys

[tobir91]

I've been trying for several days to read the PIN from the old cluster. I purchased both an Iprog and a UPA-USB adapter, but unfortunately, I'm still unable to read it. Any further guidance would be greatly appreciated!
The Cluster is a Magneti Marelli
so I´m struggling with it

you will need to open them and read it directly off the board

[tobir91]

Yes, I opened it,
I have acc Rst gnd and bdm I Connect all, but nothing can read or did you mean soldering out the mcu ?

MM dash have motorola not 93c86 as VDO.

[tobir91]

Yes that’s the problem, the other one are fine

Choose OSC 6000Mhz and use this connection

Hi everyone,
First of all, thanks a lot for all your help so far – I really appreciate the support from this great community.
Good news: I finally managed to read the EEPROM using UPA-USB! 🎉
I feel a bit dumb now for trying all this time with iProg – lesson learned the hard way 😅
Anyway, I’ve attached 4 files to this post – two reads each from the old and the new cluster (just to be sure, I read each one twice).
If someone could please help me extract the PINs from these files, I’d be super grateful!
Thanks again in advance 🙏
Cheers!

In my mind, it hink both files not complete, can i read with the upa - usb a secured mcu

[lupu_sandu]

Is not secured MCU. You choose wrong in UPA
