Thanks for the added information. I would not have guessed what you wrote. Is the engine indeed a U.S. market, early OBD-II M44?
If it is, its DME won't be happy without wheel speed pulses from the ABS unit. The signal is a 12V pulse train that is 48/9 (5 1/3) times faster than the speedometer speed pulses from the rear differential.
