fuel pumps can go bad, but the warranty on these have been extended to 6 years and 100k miles.

These cars can be heavily modded, so I would be wary of private or non-cpo cars. If you buy it cpo, you should be ok as any modifications would have been ideally caught and cleared by bwm.

If you buy private, I would ask the owner if they have done any mods. If they say yes, be wary of what mods and for how many miles.

If they say no, I would still look over for possible modifications to FMIC, down pipes, exhaust or piggy back.

If its private, no matter what, I would bring the vin into a dealership and ask them to see if its warranty is still good and not been flagged as modded with a voided warranty.
