Good evening,

Thanks for taking out time to read my post. 

I have a 2009 BMW 328 IX 2 door coupe

Ok. The facts:

- I hit a pothole and it started losing accelerating power, have a stall while acceleratin and would cut off

Lights on the dashboard: 4x4, ABS, triangle with an arrow going around it, check engine light

- but would reverse with NO problems

- Eventually drove after allowing to sit and then key put in to restart it but would cut off and did so several times and then I had to restart every time

- after getting diagnostic, I was told I needed a new battery and got it changed 

- drove it with it off and on cutting off til one day it completely cut off

- No lights on dash. fob stuck in ignition. 

So what do you think is wrong?
