At a glance
- Years: 2003 to 2010, saloon (E60) and Touring (E61). The facelift came in 2007.
- Reliability: 2/5. The M54 petrol six is sound, but diesel swirl flaps, N53 injector faults and water and electrics problems pull the car down.
- DIY: 2/5. Blanking the swirl flaps is a job for a competent home mechanic; most other faults need a workshop.
- Biggest risks: diesel swirl flaps that break, N53 injector and pump faults, Touring air suspension, and Dynamic Drive or Active Steering repairs.
- Prefer: a 2.5 or 3.0 M54 petrol six (520i, 525i, 530i), or an M57 diesel with its swirl flaps checked. Avoid: the V8 with its coolant hoses and oil use, and an N53 with no injector or pump record.
Engines and gearboxes
- 2.5 and 3.0 M54 petrol (520i, 525i, 530i, 2003-2005): prefer. The crankcase ventilation valve clogs from about 80,000-100,000 km. Check it.
- 2.5 and 3.0 N52 petrol (523i, 525i, 530i, 2005-2007): a sound engine, but watch for oil use, a worn Valvetronic eccentric shaft (the part that varies valve lift) that causes a rough idle, and the same ventilation valve.
- 3.0 N53 petrol (523i, 525i, 530i, 2007-2010): avoid unless the injectors and high-pressure pump were checked. Repairs are costly.
- 2.0 N43 petrol (520i, 2007-2010): avoid. The timing chain stretches early, and the injectors and ignition coils fail.
- V8 N62 petrol (540i, 545i, 550i): avoid. Coolant hoses age and leak, and oil use is common. Hose work is labour-heavy.
- 2.0 M47 diesel (520d, 2005-2007): avoid unless the turbocharger and swirl flaps were checked. The turbo is the weak point.
- 3.0 M57 diesel (525d, 530d, 535d): prefer, with the swirl flaps checked. Look for cracks in the exhaust manifold, which cause a cabin smell.
- 2.0 N47 diesel (520d, 2007-2010): see the BMW N47 diesel guide.
- Manual gearbox: the clutch wears from about 120,000-140,000 km, and the dual-mass flywheel (a two-part flywheel between engine and gearbox) may need replacing near 200,000 km.
- ZF 6HP six-speed automatic: prefer with regular oil service. Avoid a car with an oil leak at the gearbox pan.

Before you buy
- Diesel: ask whether the swirl flaps were removed and blanking plates fitted, and ask for proof. A broken flap can damage the engine. Bad result: no proof of the work, or a loss of power.
- N53 petrol: ask for records of the injectors and high-pressure pump. Bad result: no records, or a rough engine. No repair price is confirmed.
- Touring: check the rear air suspension. Ask for records of the air bags and compressor. Bad result: no records of the bags or compressor on a high-mileage car.
- Dynamic Drive and Active Steering: look under the car for hydraulic oil at the stabilisers and the steering rack. Test the steering on a straight road. Bad result: oil, a warning light, or a wheel that sits off centre. Recalibration is a workshop job.
- xDrive: ask for the transfer case service record. Bad result: no record of work by about 100,000 km.
- Automatic: check under the car for oil at the plastic pan. Drive the car in D, D/S and manual, and check that the shifts are smooth. Bad result: oil under the pan or jerky shifts.
- Body: check the sills, spare-wheel well, rear wheel-arch flanges, boot lid seams and the front where aluminium meets steel. Use a paint thickness gauge. Bad result: filler under the paint, or rust through a sill.
- Water: lift the boot carpet and footwell carpet. Clear the sunroof and scuttle drains. Bad result: damp, water marks or corrosion near the battery and control units.
- Front end: lift the car and check the front arms, ball joints, bushings and steering joints for play. Bad result: knocks over bumps or in the steering.
- Petrol sixes and V8: look for blue smoke after idling and oil stains under the engine. Ask how often oil was topped up. Bad result: smoke or frequent top-ups.
