Modern Scanning Equipment
A code reader will only retrieve and clear a subset of the information supported by your on-board diagnostic system capabilities, but a scan tool would retrieve all of it. High-end scanners provide real-time information, however this information is filled with a lot of limited information that most drivers don’t require.
These tools have ten various modes of operation, but if you’re seeking to verify the information yourself, you won’t need to be familiar with them all. The first four, which include the data, reading codes, and clearing codes, are really all you need to be aware of. For instance, the first mode displays real-time sensor data in real-time. The second mode enables you to get a snapshot of all the information from the moment the situation was first reported. This can assist you pinpoint the precise minute the issue arose so you can have a much clearer understanding of what caused it.
The codes that were saved in that little computer system are displayed in the third mode. The majority of these start with the letter P and then have four numbers following it.

The swiss army knife of BMW software is the BMW Tool32. It resembles how the Windows DOS command box appears to operate. You can use it to read the fault memory of certain control units, apply specific operations to the control units, or reset the service. BMW coding is another usage for it.
Software Suites for Dealers (User-Friendly Tools):
An older version of dealer-level BMW diagnostic software is called the BMW DIS. This program, which made use of the GT1 system, was created in 1994 for BMW dealers. In order to do diagnostics, programming, coding, display live data, read modules, and read faults, the E39 dealer uses DISv44. The most recent update to the original DIS coding and diagnostic software is called DISplus.
Currently, all Exx and Fxx vehicles are diagnosed at the dealer level using the BMW ISTA/D, also known as RHEINGOLD. It is intended to take the place of the previous DIS diagnostic software.
Another modern dealer-level diagnostic tool is the BMW ISTA/P, which took the position of the earlier SSS Progman programming tool.
