OBC Code on stomp test

My '94 740iL was running rough so I did a stomp test and gave me a weird code. After the initialization flashes it gave me a series of short flash and a long flash, short, long, short, long ....... with no pauses in between. Bentley don't have anything on that code, which is typically a four-digit code. I reset the code by holding the stomp for at least 10 seconds and it cleared, giving me a 1444 code. What could the short-long flash code be?????

I actually have never tried a stomp test, as the stomp test works only on U.S. spec cars.
Maybe someone familiar with that system can chime in
