hello, I have a copy of the original TIS cd the bmw dealership uses. It is basically the service manual the technicians use at the dealership. It contains all types of info from pictures of the actual parts to symptoms and diagnoses, special tools required, torque specifications, technical data, repair instructions and diagrams of all the parts for the M5 not to mention all of their cars from the 320's to the new e46 models, this is the cd the dealership doesn't want you to have because of the information inside of it. if you want it let me know, I will give it away for 40.00 plus shipping, it will pay for itself the first time you use it. Email me if you want it. thank you
