hi everyone just wondering if anyone can help. i have a 5 series BMW with a problem with ABS light that comes on and then goes out for no apparent reason but when this light comes on the speedo goes off also. havent had the car to an auto electrician he said it was the wheel sensore and bearing but these have been renewed yet the light still comes on but can also go off when it feels like it. cant think of anything else it could or should be as iv changed bulbs and checked all belts on the car. does anyone have any ideas as to what this could be? your help would be much apprieciated as im at a loss!
