The i5 is BMW’s electric 5 Series — common variants are a single-motor RWD eDrive model and a twin-motor M60 AWD performance version; the AWD M cars trade some range for much stronger acceleration. Check whether the car has the heat-pump / battery thermal management option and whether it has had recent software/firmware updates; both affect real-world range and battery longevity. Also confirm CCS fast-charge behaviour and whether it was regularly fast-charged or mostly charged at home, as that influences battery state-of-health.

• Battery state-of-health report (logged capacity vs new) and record of DC fast-charge usage — heavy fast-charging can accelerate degradation.
• CCS charging port and Type 2 cable condition; confirm fast-charge negotiation works on a public charger.
• 12V battery condition and any warning messages in the vehicle’s diagnostics (12V failures are a common EV fault point).
• Check for uneven tyre wear and recent alignment — instant torque on EVs can accelerate front tyre wear.
• Confirm all HVAC features work (climate preconditioning, heat-pump if fitted) and check screen/software responsiveness and that any open recalls/OTA updates have been applied.
