had the same issue - DSC and hand brake in amber when driving for like 20 or so mins. it sometime reset it self when turning off engine and back on. i run diagnostic and it showed error on pressure sensor 2. did some research on internet and bought myself a DIS scanning software, i performed steering angle sensor recalibration - seemed to work. havent had the error come back so far for 2 days. hopefully permanent fix. 318i E46 2004
