Cic controller back lights

Burny · 01-25-2018, 11:51 AM

Hi,
Recently got a 330d with cic idrive.
Hopefully it's something simple but the idrive controller isn't illuminating at night, all the buttons I'm sure are backlit red but mine doesn't light at all, works as it should apart from this.
Is it possible to turn these off or Is it the bulb/leds have gone?
I've googled the problem but can't find a single thread that just mentions backlights only controller not working.
Thanks

Bump, anyone got any ideas or advice, is it possible to to turn the controller back light off? Or anyone had similar issue.
Thanks

I haven’t seen any settings to turn it off in the I-Drive,
Stupid question but you never know, are your headlights on?
I looked at mine last night and saw when the lights were off there was no back lighting.
Just worth a quick check...

Thanks for the reply mate, yes I have auto headlights so lights definitely on, will try turning the lights on manually just to check.
Thanks though

Andy198712 · 01-26-2018, 08:02 AM

mine was off on 0 and on when switched to Auto so shouldn't make a difference

Should be lit up whenever the lights are on.

It's the light inside unfortunately unless you lift the centre console panel and check the wiring. Pretty sure its just the bulb blown if the controller itself is working.

That would mean a replacement though.

Thanks for the replies, if it is the actual bulb gone is it just a case of swapping it for a new one or would it need to be coded to the car?

Hia.. ive got the exact same problem on my CIC controller ☹ did you get any further with yours??

Burny · 02-10-2018, 06:27 PM

Hi,

No sorry didn't find anything else out, I've just got used to it now to be honest.

Yes the CIC can turn the backlight off in the menus.

Normally pressing the knob or any action that requires CIC display turns the backlight back on.

It may be that your backlight controller is shot.

Try shining a flashlight at an angle on the display to see if is still working but the backlight is out.

You could also have a problem with the backlight connector or voltage regulator. Normally the latter is what goes out the most on LCD displays.

Hi opjose, it's the actual controller near the handbrake that doesn't light up mate, the screen is fine, the controller works fine it just the buttons don't light up mate, thanks for the reply though.
Thanks dean

Mick_borthwick · 02-12-2018, 08:35 AM

Ive checked the fuse in mine. It wasnt blown at all. So none the wiser.. i wounder if they can be stripped down to replace the bulb/led?

Burny · 02-12-2018, 02:14 PM

If you find out anything, please let me know mate👍

Does the light next to the shifter column come on when you turn on the lights?

I believe that and the idrive controller are hooked to the same 12v source.

Can definitely be stripped down and leds replaced

Theres a few companies that do this now to change them to white etc

Burny · 02-17-2018, 09:59 AM

Thanks for that any idea the name of any companies, would like mine sorting.
Thanks

opjose · 02-17-2018, 12:39 PM

Do your shifter lights come on?

Burny · 02-17-2018, 01:51 PM

Mines a manual mate so no shifter lights

SG_E90 · 02-17-2018, 01:56 PM

Either the unit has gone bad or the circuit in FRM module has cut power to it.
Does your radio backlight and window switch backlight work as well or no?

Burny · 02-18-2018, 02:19 AM

Pretty sure everything else lights up, the controller works fine, it just doesn't have back lit buttons.
Thanks

kycs do this

Burny · 03-15-2018, 03:23 PM

Treated myself to a foxwell nt510 and scanned and I'm getting A2CD/present CON control unit under voltage, and bmw part number 9189048 which on realoem is the cic controller, I assume that's the reason I have no lights on the unit.
Does anyone know if this points towards a faulty cic controller or a voltage issue to the controller?
I've tried to search for the error code which I think is the A2CD part but can find nothing
Thanks
