Used BMW 5 Series Saloon 2017-present review

Bodywork

The 5 Series is a big car, and while you get parking sensors as standard, you should still check the alloy wheels for kerb grazes. Smaller ones are less likely to attract damage, but irrespective of wheel size, a sizeable chunk of metal missing from the wheel rim might suggest a high-speed kerb impact that could also have affected the suspension system.

Curtain airbags may have propellant which may have a humidity level higher than specification and in the event of a collision may not deploy correctly increasing the risk of injury.

If the retaining ring inside the steering gear has not been fitted correctly the sealing cap would not be fixed axially and might start moving. If the sealing cap has moved the ball return channel would not be fixed anymore and might move out of position possibly resulting in a ball jam accompanied by an extensively increased steering force and possibly lock.

The engine counterbalance shaft bearing bushing into the crankcase may be out of specification

The battery cables on the 48V starter generator may not have been sufficiently secured during the production process.

The rear drive shafts may not fulfil the durability requirements.

In very rare cases welding beads were not always completely removed in the cleaning process during battery production.

A possibility of impurities contained in the HV batteries may cause short circuit.
