I thing extern Immo Box
Hello I need to disable immo on this 1995 Passat 1.6 Petrol,
BOSCH 0 261 203 686/687
037 906 258 AM
I have removed ECU cover and this is what 's inside (picture below), so what do I need to do to disable immo?
Tell me what to scan and I will scan it, and than upload it here (if it's needed).
Thanks in advance!

Hi thanks for help but where is 24CL02 eeprom located? I can't seem to find it anywhere on the board. Here is the picture of the PCB (other side):

27C512 ... i think that is the eprom you have to dump
I am not sure, and also i have not any tested solution to give you :/
check if there is any 27C512 chip around there ?!!

I don't think there is 27C512 on the board I can't find it. That eeprom has 28 pins and only 28 pin component is B 58 157 (you can see in the picture it's very big)
Google says that's the one ... you have to do your "homework" ...
by number and manufacter on google ... is that be able to re-programmable or "one time- fix programmable"
that means you will be able to read it but not to reprogramm it ...
maybe someone who has try to immo off same ECU as yours, got more infos to give you :/

I've found out that 27C512 needs to be erased with the UV light, and only then data could be written on it. Can someone confirm me that it is possible to turn off IMMO this way? If yes, can you send me the immo off files? If not, what are the steps required to do this?
Thanks!

Passat 1995 must have immobox
In that case, remove immobox and find mcu TMS or Motorola, read it with a programmer to find PIN wich one do you use for the programming one new chip(key) with VCDS
Must prepare one pcf 7935 before programming
