Buying Tips for 2008–2013 BMW X6 (E71)
- ✓Check the electronic parking brake (EPB) actuator; listen for a loud screaming noise when applying the handbrake, meaning it's failing.
- ✓Inspect the rear boot floor for dampness; water ingress from poor seals will destroy the expensive modules housed there.
- ✓On the 30d/40d diesels, listen carefully for timing chain rattle on cold startup; a stretched chain is an engine-out repair.
- ✓Test the xDrive transfer case for juddering at low speeds, which is often caused by owners fitting mismatched or incorrect tyres.
- ✓Check the condition of the massive rear tyres; the X6 has a very aggressive staggered setup, and rear tyres are shockingly expensive.
- ✓Verify the rear headroom and boot space; the sloping roof severely compromises practicality compared to the X5.
