scirocco makes a good point. The BAD engine has several serious weak points: the high internal temps make the plastics age faster; It was only used in a few Golfs, Boras (never the Lupo!) and the A2, which means short engines are extremely hard to come by, and the inlet manifold flap issues and resulting EMLs are going to become a pain in the rear as time goes by. Let's not talk about coil packs.
The 90 has its own problems with VTG turbos, blocked EGRs, and fragile intercooler / Tandem pump seals, never mind injector harnesses.
The most robust is probably the AUA *if* it is looked after well with regular oil changes so the piston rings are kept clear. That also only has one ignition coil. Early AMFs are only Euro 3, the BHCs seem better. But all the diesels suffer with the oil pump chain issue. Watch the E3 become an issue also in the UK with regard to clean air zones.
