So I bricked my ecu awhile ago. And I got a used ecu out of a all road. It's a 4d0907551k. I plug it into the car. And it starts up and shuts down right after.

My car is a 2000 s4. It had a A box. I put a single turbo on. I also have a 85mm Hitachi maf. I had it running on my a box before. Vcds is only showing a code for open circuit 02 sensor.

I have a stock MBox file I can flash to it. But please help. I was told the ecu I got would not have an immobileizer. Is that right?Huh

4B0907551K is a 2000 A6 Bosch MAF 6 speed non immobilizer. If the car is shutting off, something else is up.
