ABS , DSC LIGHTS ON and (!) this morning

[kristianbmw21]

Hi everybody First of all , Sorry for my bad english im from lima peru
and i bought a 33,000Km M3 e92 2009. DCT a month ago

and today i started up the car on morning and some CEL CODES APEARED.

1-(abs)
2-DSC or something like that.
3-(!) that its from tires level i think.


well ive been looking on internet for this codes and i read on some threads that can be caused by low battery level on car, low brake fluid, or maybe abs sensor/module control

I know i have a bad battery on the car and i thing it might be caused by that.

please i need somebody to tell me if they had the same problem and fixed it by changing battery and cleaning codes on obd2scaner... i dont know what to do i dont want to take it to the dealer right know because i dont trust them im afraid they are going to say its other stuff involved. and maybe its not a big deal.


please ill wait for your fast responses.!

thx u all!
