 Wolf,
 One of your ABS wheel sensors is not performing well.  If you were to scope
 each pickup you will find the culprit.
 I would think one of the ABS hub rings is dirty.
 As your speed approaches 160kph the ABS sensor signal diminishes, the ABS
 control can no longer detect the signal and that causes the ABS fault.
 Cheers,
 Rod...

 The ABS light on the dash would go on now and then when driving over rough
 road surfaces.
 I've just replaced the two front ABS sensors as one of these was damaged.
 The rear sensors were cleaned as there was no apparent damage.
 Now this ABS light goes on and stays on after hitting 160kph (100mph).
 When you switch on the engine again the light is off and of course goes on
 at 160kph!
 The local BMW garage is baffled.
 Maybe someone on the digest could help?
 Thanks and best regards,
 Wolf

Wolf,

In case you haven't already solved the problem.  I had similar symptoms on my 
'85 E28 535iA, only at lower, more legal speeds.  My wrench said rear wheel 
hub sensor rings need replaced (they rust over time and the sensors can't 
pickup clear signals from the rotating cogs on the hub).  He was right, in my 
case.
