I'd buy a new turbo but I would go for original Borg Warner, not any of these aftermarket suppliers. If it's a K03, any used turbo you buy will most likely have the same issue as yours does or will fail not long after. There's a reason why they are under $200. Reconditioning it is another moneypit I'd avoid because they are very hit or miss and in most cases cost as much as an aftermraket Autodoc turbo. Between recoditioned and new aftermarket, go with the latter.
