My 320 has developed a braking/cruise fault. This does not happen all the time though. Sometimes when I brake I feel the ABS shutter as if on snow and then I lose the cruise control. If I switch the car off and restart it again it is fine until I brake again.

 

first check your tire sizes, if they are differnt this can happen. could also be anesp issue

 

tyres sizes ok...esp and bas showed up at one time but that was sorted,,,,,this fault seems to be intermittant
