Not merely has BMW electrical architecture changed over the past decade, but so contains the equipment to service them. The gear is different, the interfaces have changed plus the complexity of setup and use.

Early tools

Within the 1990’s, the gang Tester One (GT1) was introduced. There were several versions, like DIS Plus (stationary setup), though the GT1 is among the most common and it is after that be referenced here. The GT1 is often a portable device which contained a rechargeable battery. It features a touchscreen technology for quick use. It contained software for Diagnosing and in addition had software called TIS (Technical Information Display) the Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So from the same tool, you can Diagnose the situation, research how to replace the component and then perform needed initializations for your new part. Two interfaces were utilized: EDIC (yellow interface) and the OPS (orange interface). Later versions in the OPS were called OPPS, simply because they carried additional diagnostics for your Byteflite system and they also were also yellow, but much bigger compared to EDIC. Authentic GT1s are on the portable touchscreen unit. There are lots of “cloned” units on the market, adapted to be effective on the PC. Either genuine or cloned, the interfaces work precisely the same and correct by using an Ethernet port.

Later versions in the GT1 software removed CIP, and moved it with a separate computer (for storage), however accessible from the GT1. This new software was called Progman (short for Program Manager). This new software contained all the CIP functions and added new features like multiple car programming and dual channel programming for each and every car (DIAGBUS and a lot bus simultaneously).

Third Generation equipment

Go forward about 2008 when the Third Generation (3G) of apparatus was published: ISIS. The contents of ISIS are really large, that dedicated servers are set up with the dealership. An internet version is available for the aftermarket for a small charge, called OSS. It may be bmw esys coding. With the introduction of ISIS comes a fresh interface, called ICOM. Previous interfaces (EDIC & OPS) won’t work with ISIS. ISIS consists of a few parts, since it completely replaced GT1 & Progman. The main part of ISIS that is used in the shop is termed “ISTA”, that may be further broken down into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.

Comparison

GT1s can be found anywhere you want to, including eBay for cheap. BMW realized that the tool was easily cloned and sold worldwide. Many levels of security have been place into the creation of ISIS to prevent this, in both resident servers and internet based versions. This makes it more difficult for non-dealer shops to be effective for the newer cars. You are likely to believe that because the GT1 was discontinued during 2009, you can just keep using for several more years until the newer system became more available, however, BMW stayed a stride ahead! Every time a car is programmed using the new ISTA/P, it upgrades the software after dark a higher level what Program can recognize. Which means, after a car has been updated with ISTA/P, you may never use Progman on it again, rendering the “cloned” versions useless with that particular car. Also, every time a new module is installed, the software which is pre-installed with that module can also be newer compared to what Program can recognize, which could stop the entire programming process, forcing the auto being programmed by ISTA/P.

So what does which means that for your BMW owner? Because of the newer systems, many BMW owners can no longer repair the cars themselves. Many aftermarket shops may also be sending the cars to dealerships consequently. However, not all aftermarket shops have fallen behind. There is a small selection of of BMW specialty shops that stay with the surface of manufacturer technology, so that no car is turned away! While looking for a location to service your BMW, make sure they could do ALL aspects of repair, including Diagnostics and CIP!
