HELP! Bosch MSA12 0281001316 Immo problem (Audi 80 TDI 1Z)

by **xmirko** » Sat Feb 14, 2015 1:03 am

Hello everybody!

I'm new on the forum, please forgive me because I cannot speak french! I'm trying to disable Immo on Audi 80, 1.9 TDI engine 1Z, ECU 028906021AP, Bosch MSA12 0281001316/317, eproms 2 287 357 875 / 876. The original eeprom contents is lost because it was mistakenly read in 8-bit mode instead of 16-bit mode before programming. After several failed attempts, I've written eeproms from 028 906 021 CQ golf TDI and the car starts, but it starts slightly more difficult than with old ECU. Also, there is 65535 - Internal Control Module Memory error which cannot be cleared. Tried logging in with 12233 and resetting all settings to factory, didn't help. Could anyone help and send me the images which wouldn't have 65535 error code, work OK and would permanently and reliably disable IMMO?

Please help! Thank you.

Thanks for the quick response and your help! The problem is, the owner did a remap/tuning so he doesn't want to change the firmware. Do you have any other solution, or maybe other tuning maps?

I don't know how to do that. Is there any way to disable immo by altering the immobox dump (93c46) ? Thanks!

Read immobox and make a transponder with zedbull

can I change the MSA 11 ecu with a MSA 12 ? How is the problem with the immo ? Is it possible to install the immo too?
Beside of the immo, are there any other parts that need to be changed ?
N75 needs to be changed, anything else ?
