Water pump OEM BMW or OEM Volkswagen

my water pump went at 80K (KM)'s (got it towed to georgetown VW) and when i got my OEM replacement it was metal... compared to the plastic one they took out... Saw it touched it... (they showed me the old plastic one) i thought it was weird and they said in 2002 and after they have metal water pumps... before that it was "plastic"? anyways its in and i have a metal one... and i got it from a VW dealer... OEM part...

They also mentioned that the waterpump is leaking really bad and is shot and needs to be replaced.

I bought my 2001 Jetta with 80k on it. It came with a broken water pump (plastic) plus 6 belt valves and a quarter of the teeth missing from the timing belt. The pump was in about 30 pieces and the damage to the valves was do to the water pump.

My plastic Water pump went at 40k... Im at 56k now and im switching out for a metal one with my timing belt and everything.
