These are issues documented for the BMW 135i in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

The TSB's own stated symptoms (rattling, loss of power, warning light) should be noticeable on a normal test drive once advanced enough to log fault codes. Earlier solenoid-tier issues may only show as rough idle or hesitation. A scan tool confirms either tier is present; distinguishing which tier requires physical inspection, not something a buyer can do unaided.
Early-stage or intermittent HPFP degradation may not present consistently on a single test drive - a car that starts and drives normally on the day of inspection does not rule out the defect, since the failure is thermal-load-driven and can be intermittent before becoming a hard fault. A VIN check with BMW South Africa and a live fuel-rail-pressure diagnostic under load are more reliable than driving impressions alone.
