The parts cd covers all models except the E3, E9, 2002. It is the same cd used by the BMW dealers when you call to look up a part. It has the part numbers for all the parts on your BMW, whether it be a Euro model, Canadian model, or US model. A huge help for the do-it-yourselfers....just bring up the area of the car you are working on, and find out just what you need to do the job right. The tech cd covers all models beginning with the E30. Other models included are the E30, E36, E46, E34, E39, E31, E32, E38, X5, Z3, Z8, and all the M cars in those series. The tech cd is what most of the dealers look at when you bring your car in for service. It not only includes the complete service manual, but also includes recall information, tightening torques, and symptom diagnosis. This is also a must have for the BMW-do-it -yourselfer. These cd's have helped me a lot. Email me at black850i@hotmail.com for pricing info. I take money orders, checks, or Paypal....I ship internationally as well.
