[autodestruct]

So, my battery died in my 2011 335is e93. It took the FRM3 out along with it (lost my windows and interior lights, headlights always on, etc). I ordered a programmer and was able to reflash the FRM3 successfully.

After I reinstalled the FRM3, everything looks like it is back to normal, lights work, windows work, etc. But, my idrive controller doesn't seem to work.

The idrive system itself works, I get a display, the radio works, and I can use the radio buttons to change functions and get new screens. I just get no response from the i-drive controller/joystick itself.

In Protool I get the following errors:
MASK/CCC/E1CD
MASK/CCC/E1CC

ISTA shows 'no communication' with the controller.

I checked the idrive controller, and it's getting 12V. There is also voltage showing up on the KCAN bus.

Before I look for another controller, is there anything else I should check? Is there any programming that is required to recognize the idrive controller? I copied the VO from the CAS to the FRM - did I miss something else?

Thanks!
