The E39 5 Series is often described as one of the best saloons BMW has ever built. Produced from 1995 to 2003, it combines a timeless design, excellent build quality and a balanced chassis with a wide range of six-cylinder, V8 and diesel engines.
Today, it is a respected modern classic and an affordable way into a comfortable rear-wheel drive BMW. But age brings maintenance needs. In this buying guide we explain the E39 5 Series engines, versions, common issues and what to check before you buy.
Why the E39 is so respected
The E39 is admired for:
- A timeless, elegant design that has aged very well.
- A high-quality interior with comfortable seats.
- A balanced chassis with aluminium suspension parts on many versions.
- Smooth engines, from straight-sixes to V8s.
- Comfort on long journeys.
The M5 of this generation is a legend in its own right. Our M5 E39 buying guide explains that car.
Engines
The E39 was offered with many engines:
- Six-cylinder petrol: early cars used the M52 family in models such as the 520i, 523i and 528i, while later cars used the M54 in the 520i, 525i and 530i. Our E46 330Ci buying guide explains the M54.
- V8 petrol: the 535i and 540i with the M62 V8.
- Diesel: the 520d with a four-cylinder and the 525d and 530d with six-cylinder diesels.
Choose based on your use: a six-cylinder petrol for smoothness and simplicity, a V8 for effortless performance, or a diesel for long distances.
E39 5 Series common issues
Points to check include:
- Cooling system: the expansion tank, radiator, water pump and thermostat age and should be replaced preventively. Our article on BMW cooling system problems explains why.
- VANOS: worn seals can cause rough idle and loss of low-speed torque on six-cylinder engines.
- V8 timing chain guides: on the M62, plastic guides can wear and break, causing noise and potentially serious damage. Listen carefully on a cold start.
- Front suspension: thrust arm bushings and ball joints wear, causing vibration under braking. Our article on BMW vibration at speed explains this.
- Instrument cluster pixels and other age-related electrical faults.
- Oil leaks from gaskets. Our article on BMW oil leaks explains common points.
- Swirl flaps on some diesel engines. Our article on BMW swirl flaps explains the risk.
The E39 Touring
The E39 Touring is a practical estate with a separately opening rear window. Many have self-levelling rear air suspension.
Check the rear ride height and look for leaks in the air springs. Test the tailgate, the rear window and the load cover. Water leaks into the boot can damage electronics, so check the spare wheel well. Our article on BMW water leaks explains how to find leaks.
Gearboxes
The E39 was offered with manual and automatic gearboxes. Manual cars are popular with enthusiasts, especially with the six-cylinder and V8 engines.
Automatic gearboxes can be reliable, but fresh fluid is important on old cars. Our article on BMW transmission fluid explains why. Check for smooth shifts and no delays.
Rust and body
The E39 has good corrosion protection, but cars are now more than 20 years old. Check:
- Wheel arches and sills.
- Jacking points.
- Door bottoms.
- The boot lid and around the number plate lights.
Our article on BMW rust explains how to inspect and protect an older BMW.
Running costs and parts
Running costs depend strongly on the engine. Six-cylinder petrol and diesel models are relatively affordable, while V8 models use more fuel and can need expensive repairs, such as timing guides or cooling system work.
Most service parts are still available from BMW and independent suppliers, and BMW Classic supports many older models. Interior parts in good condition can be harder to find, so a car with an intact interior is a good sign.
A sensible budget for the first year should include:
- A full service with fresh fluids and filters.
- Preventive cooling system work.
- Suspension refresh if the car feels loose.
- Tyres and brakes if they are old.
Many owners say the E39 rewards preventive maintenance with years of comfortable driving.
Test drive checklist
On the test drive:
- Start the engine cold and listen for rattles, especially on V8 models.
- Check the temperature gauge stays stable.
- Feel for vibration under braking.
- Test all electrical functions, including windows, mirrors and the climate control.
- Look at the service history for cooling system and VANOS work.
Our complete checklist for buying a used BMW covers other checks.
Is the E39 a good buy?
A well-maintained E39 is a comfortable, elegant and rewarding modern classic. Good examples are becoming harder to find, and values of the best cars are rising.
Buy on condition and history rather than mileage, and budget for preventive maintenance, especially the cooling system and suspension. Our guide to buying a high mileage BMW explains how to judge older cars.
