Changed the battery and now I have 2A3F, 2A77 and 2E8E codes.

I changed my battery in my 2011 328i with a Duralast Gold battery from AutoZone. I plugged everything back in and rechecked but I am now getting a 2A3F, 2A77 and 2E8E codes. I checked the vvt fuse in the front of the DME box in the engine bay but it looked good. I cannot find a good answer online so I thought I'd ask here, I also attached the INPA code screen to this post. Any thoughts are appreciated.

It looks to me as if you missed re plugging in one of the IBS connectors or if you didn't, then one got loose.
