They do have their problems, The mercedes 5 cylinder 2.5 om602 is much better design (and 20 valve om605 2.5 liter is way out of the league above from tuning/durability standpoint)
First problem is the injection pump wich is semi electric, you can mount a mechanical pump from an earlier 2.4 6cylinder (the engine before) also early engines had waterpump with plastic impeller and the would often crack in the shaft resulting in engine overheating and literally self destructing, the cylinder head channels are somewhat tiny resulting in max power potential of only about 210hp and for durability about max 180hp
and like most 6 cylinder engines it also has problem with cooling the most rear cylinder....
Wonderful smooth engines, miss my bmw sometimes....
Love those bmw 6 cylinder engines
In vw they used the aaz 1.9 engine often in transporters or later cars, VAG began replacing the 1.6 with the 1.9 around 1992-93 if i remember correct
