Fixed obc backlight...but

[mark///m3]

i used the diy and soldered in some new bulbs from radio shack for $2, so far a home run. i even fixed a couple bad connections on my cluster board while i was at it.
now for the bad my obc doesn't fully work. i have clock date and timer functions but no others, temp avg mgp mph... it just reads pppp. i checked the wiring harness and all is good. i also tried to reset but it did not work. my only other thoughts are that it might be a bad code plug. wondering if anybidy else has come across this problem and has a solution

With the key in the "Radio" position (Radio and OBC light up, but not the instrument cluster), press the "CODE" button. Then push the little reset-hole with a Pen and hold it, 'till the computer blinks in the display, and it will ask you for a time and date entry. - You now have re-adapted the coding plug to the computer. - Normally the computer goes into a PPPP mode when the car has been boosted, or some other very drastically voltage changes have occurred.

Also disconnecting the battery then reconnecting it usually sorts it out.

i tried that but only m mph light blinks, maybe i need to hold it longer?

the reset stuff didn't work so i ordered up a working used obc from a 325e. my only other thought could be that i swapped clusters for a higher tack and maybe this has something to do with it

Removing the fuse for the OBC works also
