Next to the service button is a green triangle with a sorta reverse check mark - does anyone know what this means

Sorry we have no way to recommend any location for the key.

Hi Mark,

On your particular vehicle, this symbol means low traction. Your vehicle is automatically adjusting power output to compensate for low traction. If the road conditions are not significant enough for this low traction to be a reality, then your wheel spin sensor would likely be faulty.

Refer to Section 3-33 of your owner manual.

get in the car close the door turn the ignition on but dont start the car. wait intil the clock is displayed in the instrument cluster or push the bc button to display it. next press and hold the button on the left of the instrument cluster. an orange triangle will appear keep holding button in. next the cbs service data will appear release button. by pushing button briefly without holding you can scroll through service data. when an oil can is displayed press and hold button again. the word reset with a question mark will be displayed. release and press and hold button again oil service will reset

In 2006 BMW developed what they Condition Based Service (CBS), this means even when you change the oil and filter, the only way to reset the service indicator is to take it to the dealer, to be hooked up to thier computer. I have the same problem, I am waiting for some aftermaket code breaker to be developed to fix this problem. Hope this helps, let me know.

that indicator is for the lambda sensor, that reverse check mark thing is the greek letter lambda. lambda sensor is another name for the oxygen sensor. it is part of how the engine computer manages emissions and it also contributes to fuel economy. if it becomes defective and is not replaced the system may eventually foul your catalytic converter. hope that helps

It sounds like the DSC fault that I have on my 320ci, apparently I need a new steering angle sensor.

Could be the motor-management-warning light, but I guess it's the break-warning light. There might be too little breaking-fluid left in the lines ... A boardcomputer-readout should clarify this.

Otherwise, try parking on an ascending road with the nose pointing up, hit the hand-break and wait like 2 minutes; the light should come on. You might wanna retry it with the car's nose pointing downwards as well ... If so, definitely the breaking-fluid, otherwise probably not ;)

In any case - flashing warning light are never ok, so when you see it again and you're sure it's not just the ABS/ESP warning light, go and have your boardcomputer read-out, since it should contain useful errorcodes ..

that is your traction control. Either you pressed the traction control button it say ASR OR ESP on your console in the center next to the hazard switch.
