Hi,

I believed i have shorted my steering wheel colum switch connecting points (clock spring) by accidently touching two pins together when i was testing the connect pins. Then CDB804 fault code - No message (request, A/C, 0x2F9), receiver DME/DDE, transmitter IHKA came out.
So the wiper is actived and out of control, turn signal level not working, headlights will always on, air-con is not function. radiator fan is on MAX.
I checked the fuses, is all fine. Anyone can helps me??

cheers
