6 Most Common BMW X5 Problems
These are the faults most frequently seen on the BMW X5 by UK garages — ranked by how commonly they occur and what they cost to fix.
The N57 diesel used in 30d and 40d X5 models can develop timing chain wear on higher mileage. A cold-start rattle needs immediate attention — repair is very expensive on this engine.
💷 Typical repair cost: £2,000–£5,000+
X5 air suspension is complex and failure is common on older examples. Compressor, air lines and air bag failures all occur. The car sits noticeably low on one or more corners.
💷 Typical repair cost: £600–£2,500

Older X5 45e PHEV examples are showing battery degradation with reduced electric range. Some owners report battery module failures.
