Hi Tharon, Have only recently acquired  the tool, currently it is partially configured for R1100S 2 spark as it can interrogate the MA 2.4 Motronic and get all the listed data with model code, type, variant, software currently loaded, and both BMW and Bosch part numbers, then it checks for fault codes active, and stored but not active, [ history of occurrences] any codes listed are followed by description, then if faults are fixed and no longer active they can be erased via next screen on program.When checking for fault codes on the ABS system because the software is not finished being developed for this particular model then it only lists the fault code number and no description. So one has to get a list from BMW or "Hex" as to what the fault code number means. But the system is fully finished for R1150 GS series bikes and R 1200 GS series CAN- Bus, other models are being tested and finished currently so as to cover a wider range of models.Because my bike is very close in spec to the R1150GS 2 spark model, I use this interface software when checking my bike for fault codes, as this model uses the MA 2.4 Motronic ECU but due to very slight software changes when accessing ABS codes I only get the number, If my bike was actually an R1150 GS 2 spark model, then I would also get the description beside the coded number as well.Fortunately all the sensors are within range and all fault codes present were cleared once the engine was running. Bosch think a little differently when configuring their diagnostics when compared to other manufactures of engine management systems, Were as a fault code will be generated for a speed or crank angle sensor that is not giving a signal due to the fact that the engine is not running, but there is nothing wrong with the sensor, and as soon as the engine is started and this sensor generates the required signal then the fault code clears.The only reason I got the adaptor is so I could check all the sensors were within range and I wasn't riding the bike with a sensor out of range For example; engine temp sensor, or Air inlet temp sensor,or oxygen sensor, that would allow the engine to run and in some cases very well, but would be a big increase in fuel consumption [ this can sometimes be the case]. But let me say that Bosch engineers are pioneers in the field of engine management systems and many other systems are made under license to Bosch and in my humble opinion Bosch still produce the most reliable systems available today for anything that has pistons. So chances are you won't have a lot of trouble if you look after your bike, most of the troubles come in the form of a "bad earth connection or loose battery terminals or corroded or wet connections between plugs and wiring looms, the sensors are reliable and as they say if the "smoke" remains trapped in the wire and doesn't leak out then the system will probably work OK, When the smoke leaks out of the wires then everything stops [ask any electrician]
