Other Comments or Concerns
BMW state on their Service Information homepage, "BMW troubleshooting charts, guides and aids for diagnosis are integrated into BMW service tools. Stand-alone guides for troubleshooting are not available via this website." I do not believe this is a valid reason for service information to unavailable to the independent repair community. It appears to be in direct violation of rules which require OBD service information to available to the independent repair community.

This correspondence is in regards to your NASTF service information request regarding the 2001 BMW 540i cooling system. The BMW Technical Information Website, WebTIS, used by both our franchised dealerships as well as the independent repair community contains the information you are requesting. Recommended engine coolant can be found in the Operating Fluids manual. The factory training manual “ST054 Climate Control” contains the explanation and operation of the engine cooling system. Repair instructions and technical data for cooling system components can be found in the repair manual. Guided troubleshooting is available via our Online Diagnosis application, and our wiring diagram software contains the wiring diagrams for coolant system related items as well as documentation explaining how cooling system components, such as the thermostat, function in the vehicle. For any future questions please use the “contact webmaster” link on our website or send your inquiry directly to”

Follow-up question from Mr. Hanna: "Hello, Thank you for your response and explanation. However, when I tried to access the Online Diagnosis application it would not properly launch because it was trying to communicate with hardware that should have been connected to the computer. I'm assuming this "hardware" is the BMW scan tool or vehicle interface. I was not able to find a stand-alone web based application that had service information. If you can elaborate, or possibly provide the "path" I need to follow when navigating the website, it will be greatly appreciated! Thank you, Jim Hanna

Follow-up Response from BMW: "The Online Diagnosis Program is looking for an SAE J2534 Pass Thru Device. The J2534 tool is not a BMW specific tool but a universal standard adopted by the EPA as the recognized and accepted tool for vehicle diagnosis and programming for the independent repair community. J2534 tools are available from many different manufacturers."

Final response to NASTF from Mr. Hanna: I would consider this issue resolved. At this point it's just a matter of preference, I suppose. I feel standalone web applications are best for service information but BMW chooses a different method. My concern with their method is that the technician(s) cannot test drive the vehicle as it needs to be connected to a PC/laptop with internet access while the Online Diagnosis program is running.
