Hi there!

As far al Hallgeber (correct german spelling) is concerned, that one is not located under the engine - it is integral part (no separate spare part available) of steerboard distributor. Once I had Hallgeber-failure, resulting in 4 litres/100 km excess fuel consuption with same time about 100 hp missing. It was in fact a problem with Hallgeber wire insulation, underneath the distributor, which was caused by animal biting. New piece of wire and ABH is back to performance.

So, have a look at wires leaving distributor, maybe going to/coming from the sensors you were shown by other members.

Es war schon immer etwas teurer, einen besonderen Geschmack zu haben...
