Back in the day i had an old VW PD engine (which admittedly also had cam-driven injectors), but that engine was EXTREMELY sensitive to camshaft timing. 1-2mm on the cam pulley could make a significant difference to how it behaved at the top/bottom end.
They never ran properly if a garage changed the cambelt without the proper locking tools. The cars came from the factory with an optimised 'timing offset' which was written on the cam cover which often faded by the first service!

Exactly. Diesels have a tiny injection window. Any slop in the timing results in sub optimal running.
