N55 JB4 Circuit Board?

saranghae · 10-15-2014, 10:20 AM

Hey,

I bought a used JB4 for my N55 335i. I connected it up, started up the car and it gave me an engine malfunction code. I'm pretty sure I followed the instructions to a tee (my friend was there double checking the install every step of the way). Pulled it off and everything worked fine.

I just want to make sure I have a legitimate JB4 board. It doesn't say JB4 or stage 2 anywhere on the board.

Is this a legitimate N55 JB4?

Nope, that's an old Stage1 G2 board from 2008. Maybe he was using it as a Stage1 but its certainly not a JB4.
