E90 radio drank a big gulp---HELP!

TheRealPeterman · 04-21-2012, 06:09 PM

Hello members...
my '06 e90 had a bit of a problem last week when I accidentally spilled most of a soda into the dash, most of it landing on the hazard/DTC buttons, START/STOP button, all of the radio, and all of the A/C controls.

When it happened, the gauges started going crazy, the dash was flashing every possible lamp, and the radio turned off. I got it home and tended to it by disassembling the wood trim removed the radio and the A/C controls.

I proceeded to dismantle the front face of the A/C controls, cleaned the PCB, and did the same to the radio (removed the face and cleaned the pcb).

Got rid of everything sticky, right now the problem is this:
The steering wheel control dont work (none of them). The radio also will NOT TURN OFF, where before it used to when I turned off the ignition.

Besides that, everything else is responding beautifully. Do you guys think I blew a fuse or something?? ANY help is appreciated.

Normaly I would say TV tuner cleaner or some type of electronic solvent on the stuff that doesn't work.
Did you spill junk on the wheel to ? If you did you probably need the the steering wheel removed and cleaned .
I would check the fuses just to be sure, but I don't know which ones.

There are some electrical pdf's here

I would look at the DIY for steering angle sensors in the DIY section here to get and idea of whats behind the steering wheel.
