If the ABS light stays on after you start the engine there is a problem with the ABS system, there are small sensor on each wheel and when they get dirty you will bet a steady ABS light. If it comes on when you are stopping on snow, ice or rain, it is probably OK.

This is just to warn you that you have been driving for more than 2 hours and you might need a break. The solution is to press the right hand side (WIPER HANDLE) lower button and the flashing light will disengage. Good luck.

Hi, Sounds like your abs braking system is at fault. The light would normally flicker when traction (tyres loosing grip with the road) is lost, Then as regained the light should go back out, however you have a sensor on each wheel either one of those may have packed in or your main ABS control unit under the bonnet may be at fault or on the way out. Also it may be your traction control switch that could be at fault. Hope this helps.

The speedo not working causes these 3 lights to come on due to the speed of the car needed for the ABS ESP to work . Engine management light is on due to the first 2 lights . Happenned to me last night. Dont know what is up with your speedo . You have to reset the lights after speedo fixing as I am uncertain whether they will reset themselves.

its a tyre pressure senser warning light ,did u have any tyres fitted or wheels changed around?

I have a 2000 Audi A4 and the break wear sensor warning light come on for me too. It does not flash and is orange in color. I have asked the Audi dealer twice about it and they told me it's because the previous owner put aftermarket break pads on it, thus messing up the sensors. I don't know about the ABS warning and other than that I wish you luck on it.

Hi, I had the same problem. it is the imoboliser, it reads a code in your key while starting. you need to get the code in the key reprogramed. if that wont work you will need to get a new ignition barrel. Audi dealer will reprogram your key.

I had the brake light switch replaced by a local dealer. Cost was $140 and it fixed the problem. Have driven the car for two weeks since and no lights and all systems normal.
