I had the same problem with my 2016 neos 4. I had replaced the rear brake shoes and ran the bike for a while while it was sitting o the stand. The issue was simple... the engine management system thought that there was an issue with the speedometer as the Speedo reeds the speed from the rotation s of the front wheel. As the bike was on the stand the front wheel, hadn't turned while the rear one was spinning with the engine revved...
the solution was simpler... SPIN THE FRONT WHEEL, Or take the bike for a ride. Sorted
The fault code is '19'. Counting the flashes to philips TVs are given in detail by the link given below. These blinks are fault indication, and known as blinking
codes. From the number of blinks occur
at one time switch ON; you can get an idea about the faulty circuit stage
inside the TV. This will make repair
easy. For more information, check the link http://electronicshelponline.blogspot.com/ You can get details about the fault codes, blinking codes etc:
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
The D4 light is coming on to tell you that there is one or more fault codes set in your transmission control module. The only way to retrieve codes on the 1995 models is to read "Flash Codes" output by the D4 light. (See instructions below)
RETRIEVING FLASH CODES USING THE D4 LIGHT
If fault codes are present, the D4 light will "blink" when the ignition is turned to the RUN position and will remain on at all times when the engine is running.
To retrieve the flash codes, turn the ignition switch off.
Install a jumper wire between the service check connector terminals.
The service check connector is a gray, 2-pin connector located on the PCM/TCM cover under the passenger side of the instrument panel. (See picture below)
CAUTION: DO NOT use the 3-pin located next to the service check connector.
Installing the jumper will place the PCM/TCM in diagnostic test mode.
Turn the ignition to the RUN position. Codes will be output by blinking the D4 light.
Note the number of blinks from the D4 light. A short blink indicates a single digit flash code. A long blink equals 10 short blinks. For instance one short blink indicates code 1. One long blink and four short blinks indicates code 14. If there is more than one fault code, they will be output one at a time from the lowest numbered code to the highest numbered code. It is recommended that you read the code or codes several times to make sure that you are reading it correctly.
Once you have retrieved the fault code(s) re-post your question and include the information for what codes you have and someone can then help you locate the cause of the problem.
I believe you count the amount of blinks to read the codes. First blinks are first number, and second set of blinks are second number. Chaz Moto DC

BMW engine light Comes on if DME engine management system self diagnostic fault detected. Will stay on until codes are called up and memory erased. With OBDread the code as follows. Turn on ignition key, press accelerator pedal to the floor five times within 5 seconds. The check engine light will remain on for 5 sec , blik off, come on for 2,5 sec, go off for 2,5 sec and fault code will begin to flash. If more than one fault exist 2nd fault code will be separated by 2,5 sec pause. after fault codes there will be a 0.5 sec flash and light will remain off. to read codes again do procedure again. Canceling of codes. make sure fault code is present (short blink and light goes out for long period), depress throttle pedal for at least 10 sec. read fault codes again and check for code 1444 (no faults stored.) Check also the following, fuel pump, oxygen sensor, fuel injectors, engine coolant temp sensor, idle speed control valve, mass airflow sensor and too many other things.
