Unfortunately it's too easy to understand. It's true for the A4, and
for a variety of older/newer engines.
It _ISN'T_ true in the context I quoted earlier - the MB/1B engines
used in the European 200TQ (1989/90) and the 1989/90 ur-quattro.
It may be 'bullshit' for the A4 - it isn't for every engine.
