Advice for buyers
What should I look for in a used BMW X5 4x4?
Hard-driven X5s eat through tyres, brakes and steering bushes. And, remember that with a 4x4, it is advisable to change all four tyres at once.
Older diesels experience problems with fuel injection and cracks in the inlet manifolds. They also suffer faults with the air mass sensors, which you can spot on a test drive, if the car runs poorly or there are flat spots when accelerating.
