Magneti Marelli 4HV 3C0906024H

**mislav88** · 7th January, 2015, 10:37 PM

Here is the file that seems to be working without immo in Marelli 4HV ecu with BWX engine. Tried to start the car without dash several times (Ibiza 2007) and works even after waiting few hours and disconnecting battery.

Ecu is 3C0 906 024 H

Anyone who can test this please report.

Just tested on another car with same ecu and starts fine!

Looks like we now have immo off solution for marelli 4HV!

Only thing you need to do after writing file is write protect 95320 (just write 8C in status register with UPA).

I know this is an old thread, but thank you for the file.
works on a VW Polo 2002 with IAW4HV.F.
I used TL866CS (MiniPro) to program with the 'Status Reg' option to protect.
can you tell me if this 'status reg' is the same als upa?
