I drowned my GU 9 months ago and the steering wheel went under. When this happened, every single light on the dash lit up (as you would imagine). After replacing the ECU, all fuses and relays the airbag light is still on. I took it to a mechanic and it came up with codes 3E and 3B saying "Control unit failure". Is it just the clock spring? Or is there something else that controls the airbag. It's an ST model with only the driver's steering wheel airbag. The codes wouldn't clear either.
