Hi, Ive just bought a 320d e46 a few weeks ago and have notice that the following warning lights never light up, ABS, Traction control, Airbag and the brake pad. Some or all of these should light up turning the ignition on, but they all should light up during the clock test (holding the trip reset button to go into test mode, function 2.1)
The traction control doesn't work (it drifts) I've pressed the ASC button several times ranging from 1-20 seconds and the light never illuminate or flicker.
ABS sort of works, it shudders on jamming on the brakes but one wheel locks up so I presume 1 of the abs sensors at the wheel is faulty.
I presume these lights are LEDs so they cant be blown so did or could the garage i bought the car from, disable these functions with a computer??? or is there any other way he could have stopped these lights from coming on??
Checked every fuse and there all ok, none missing.
I do all the work on cars myself so I really dont want to bring it into a BMW garage, might buy some sort of OBDII test equipment if it'll help me.
Only worried about getting the lights working for now, will sort out why there lit after (if there lit)
Any help would be greatly appreciated
