I couldn't tell you if the new one would burn out, sorry, there are too many things that could have caused the last one to burn out! at the time it burnt out, was it a hot day? was it around the same time or shortly after spilling drink on the console?
I'd open up the I-Drive control knob and check for corrosion on the board before installing a new CCC, as this spill seems to be the only thing I can think of that could possibly cause that.
As it burnt before the fuse blew is, leads me think that it was corrosion on one of the boards (probably the drink spill) creating a 'close to zero ohm' short on the power, which in turn loaded the power supply circuit to max, but not enough current to blow the fuse, and then it cooked itself.
I'd start with the I-Drive knob next and then and confirm there is no corrosion
All the best,
Matt

Thank you, I'll go check out the i-drive knob and see if I can find something there.

Then I believe it would be safe to install a new or repaired CCC.
Best of luck mate,
Matt

Not a problem at all!
Good luck and I hope the new one doesn't cause you any grief. Its still strange how it burnt out like that, its possible the drink dried up now and won't cause any more issues

Hey teh_pledge,
I'm an electronics technician and do lots of fault finding to component level, if you upload a pic of the board (I've never looked at a CCC screen board before but am very familiar with complex circuits) I might be able to help you identify an issue and possible fix for the current board. Like most circuits, heat is the number one killer, followed by water. of course any short circuits, voltage spikes or component failures can also be the cause.
I think it sounds like component failure, being its just the CCC screen (I assume I-Drive is still working like the radio and voice) and could be an on board power supply which I can fix and test (I have an 04 545i too) or somebody whose electronics savvy can fix
More than happy to help a fellow enthusiast out, just need clear pictures of the PCB and in particular the area around the burnt spot (as clear as possible so the component values are visible)
Cheers,
Matt
