A BMW with a driving and performance concern simply must have diagnostic testing performed, using a BMW compatible diagnostic tool that has capability of not only displaying diagnostic trouble codes (DTC's) that have been set noting system failure concerns, but also is able to monitor operating conditions of various components and sensors during the time the problem occurs. There is simply no suggestion to make other than to have the proper testing performed.
