Since i got my 328 the ABS and traction control lights have been coming on
They only seem to come on when the car had been sitting a while like over night
when it has been driven for a while, if u turn the ignition off then back on the lights are out most of the time
i had it in the garage to see what fault codes were showing, the first time he tryed it wouldnt speak to the diagnostic. then a few days later tryed again and it through up loads of fault codes, some contradicting others. so he cleared them and i went back in today and it wouldnt communicate with the diagnostic again
the guy said he thinks it might be the main control unit that is faulty, would anyone agree?
or have any ideas what the problem might be?
if it is the control unit can this be replaced with a used one, or do i need a new one?
does a new one need to be programed by bmw?
can anyone shed any light on the mater? any help would be great, cheers
oh and as far as i know the abs is working ok
