I need to replace/reprogram the computer on my BMW 2001 530i. How do I go about

Hello, we do programming and coding for BMW; has anyone diagnose that your computer is bad?? Normally a dead cylinder could be cause by an ignition fault, need of maintenance or a faulty electric connector. We suggest that you get your vehicle to an specialized BMW shop and have a technician diagnose the problem Call us for an appointment. Thank you
