**Fec001** · 6th January, 2015, 05:58 PM

Hi!
I tried make immo off this car. Follow IUD 3.2 procedure, write immo off file to 24c02, lift up eprom PIN7 and connect that to PIN8, cut immo line pin 59. Result: car doesn't start and now pre glow light lamp is flashing too.
ECU details:
0 281 001 969
As I know there is 100% working solution but never done this car immo off.
Attachement, there is ori dump and what I tried.
I need some help!

use new eprom with WP function ST24c02/04WP and write ff from 40 to 5F

**gokey** · 7th January, 2015, 12:44 PM

**Fec001** · 7th January, 2015, 12:45 PM

Why use new eprom? WP: lift pin7 up and connect to pin8?

**Topman000** · 7th January, 2015, 12:52 PM

yes lift 7 and conect to 8.with an orig.eprom it didnt work.

**Fec001** · 7th January, 2015, 12:53 PM

Ok!! All clear now!! I have only 24c08W6 in my workshop now. Is that ok or MUST use 24c04WP

**Topman000** · 7th January, 2015, 12:54 PM

tested on 24c02/04WP - write protect

**Fec001** · 7th January, 2015, 01:18 PM

Tried with 24c08W6. Car starts fine but pre glow light flashing on IC and immobilizer fault in ECU. If delete DTC then, flashing stops until next restart. Is that normal?
