BMW Repair: breaks,ABS,centerlock and windows, wheel speed, resone

Question
good evening Mr.don
I have come problems in my BMW 325i 1994,i bought it since 8 months and the ABS light was on,when i turn on the engine mostly it will be off but after few meters it goes on again,also the break sign after 4 months goes on and i change the breaks without the sensors because it was fine but till now its still on,the mechanic clean all the sensors and check them up and he said its ok.
after that a new problem was occourd!some times and without any resone the centerlock is not working and the windows is not moving down or up till i disconnect the battry then connect it again

do you have any idea about these,is there any way or tool to reset the ABS and Breaks light,or should i change the seonsors and is the centelock problem related to any of these maybe thw whole computer need to be reset

thank you so much for your help
regards

Answer
The ABS light is not a resetable light.The problem must be fixed for the light/s to go out.You said it doesn't come on until you have moved the vehicle a few meters...sounds like there may be a wheel speed sensor that is bad...needs to be put an a scan tool to find out where.
