Title: 008 VW Polo Dashboard (Magneti Marelli) Nightmare - MCU MC9S12H256 Pin Extractio Post by: tobir91 on April 17, 2025, 12:05:02 AM Hello Experts!
I'm currently fighting an epic battle with a 2008 VW Polo dashboard (part number: 6Q0920823T), featuring a notorious Magneti Marelli unit with a stubborn Motorola MC9S12H256 MCU. This dashboard is proving to be tougher than my mother-in-law's Sunday roast! Here's my story so far: I tried using my trusty UPA-USB programmer to read the full flash dump (files attached). However, instead of the PIN I was expecting, I got...well...nothing. It seems the MCU is secured better than Fort Knox. Desperate times call for desperate measures, so naturally, I went ahead and bought an Iprog+ programmer. Turns out, this fancy gadget is about as useful as a chocolate teapot. Money officially burned! This dashboard has been haunting my dreams and draining my sanity. I'm desperately trying to get the PIN so I can code the new dashboard to the car—the old one has decided to retire early with multiple failures. Could anyone here enlighten me or suggest a different method, or maybe even save me from further financial embarrassment? I appreciate any help—my sanity (and wallet) will thank you immensely! Cheers! |
