Hi, my abs light has been coming on when I start the car and then goes out after moving forward in drive, but if I sit with it running stationary then the light stays on. Should'nt the light go out immediately after starting the engine? We've only had the car a few weeks and have'nt really got to know it yet, on a plus side just been on a 60 mile trip and computer says 38.7 mpg! better than I expected, it's been chipped and just had a service.
