VW Golf 2.0 1995 immo off

[Bane992]

Hello to all,

I have golf 3 2.0 gasoline with SIEMENS 5WP4 152, 037 906 024 F ecu, and I need immo off.

Please could you tell me which eeprom to read and to upload dump ?

And one more question, is it possible and how to do chiptuning on this ECU, which eeprom to read, and should buy the new one to write the mod or I can re-write on the old one ?

Thanks you in advance to all.

Use old one. Just save ori file first

Use old one. Just save ori file first

shouldn't old be erased first with uv light if it is windowed?
