BMW E53 X5 buying guide: the original BMW SUV

The E53 X5 was BMW's first SUV, launched in 1999 and built in Spartanburg, USA. BMW called it a Sports Activity Vehicle, because it was designed to drive like a BMW on the road rather than to be a pure off-roader.

Today, a used E53 X5 is an affordable way into a solid, comfortable and capable BMW. But many cars are now over twenty years old, so condition matters more than mileage. This guide explains the engines, versions, common issues and what to check before you buy.

A different kind of SUV

In the late 1990s, most large SUVs were built on truck chassis. The E53 X5 used a monocoque body, independent suspension on all four wheels and engines shared with BMW saloons. The result was an SUV that steered and handled far better than most rivals.

During development, BMW owned the Rover group, and the X5 shared some ideas with Land Rover, such as Hill Descent Control. However, the X5 was always focused on the road, with off-road ability for snow, gravel and light tracks.

Engines

The E53 X5 was offered with several engines over its life:

• 3.0i: the M54 straight-six petrol, smooth and generally durable.
• 4.4i: a V8 petrol, first the M62 and later the N62 with Valvetronic after the 2004 facelift.
• 4.6is and 4.8is: the most powerful V8 versions, with sporty styling.
• 3.0d: the M57 straight-six diesel, with more power after the facelift.

The 3.0d is popular for its torque and economy, while the 3.0i is often the simplest choice. Our article on BMW engine codes explains how to identify each engine.

The 2004 facelift

In 2003 and 2004, the X5 received a facelift with new headlights, a new grille, a revised interior and new engines. The most important technical change was the move to xDrive, which can vary the torque split between the axles using a clutch in the transfer case. Earlier cars use a permanent all-wheel drive system with a fixed split.

Automatic cars also moved from a five-speed to a six-speed gearbox in many versions. Facelift cars are often more desirable, but early cars can be simpler to repair.

E53 X5 common issues

Points to check include:

• Cooling system: radiator, expansion tank, water pump and hoses age on all engines. Our article on BMW cooling system problems explains the warning signs.
• Transfer case: on xDrive cars, the actuator motor and the transfer case itself can cause clunks and warnings.
• V8 engines: check for oil leaks, timing chain guide noise on the M62 and oil consumption on the N62. Our article on BMW oil consumption explains this.
• Suspension bushes: front lower control arm bushes wear on a heavy car. Our article on BMW suspension bushings explains the symptoms.
• Rear self-levelling suspension, where fitted, can sag.
• Window regulators and sunroof drains. Our articles on window regulators and water leaks explain these.
• Rust around the tailgate and lower body on older cars.

Interior and equipment

The E53 X5 has a high driving position, comfortable seats and a solid interior. Many cars have leather, heated seats, satellite navigation and a split tailgate. Check that every electric function works, including mirrors, windows, seats, climate control and the radio. Older displays can lose pixels and some parts are becoming harder to find.

Gearboxes

Most E53 X5s have an automatic gearbox, with a manual gearbox available on six-cylinder models in some markets. The automatic should shift smoothly without delays or harsh engagement. Many specialists recommend fluid changes on older cars, even though BMW once described the fluid as lifetime. Our article on BMW transmission fluid explains why.

Running costs

The 3.0d is the most economical E53 X5, while the V8s use much more fuel. Insurance and road tax can be high in some countries, depending on emissions.

Parts prices are reasonable for common items, but a full suspension refresh, a transfer case or a V8 repair can be costly. Budget for preventive maintenance and do not buy the cheapest car on the market.

Test drive checklist

On the test drive:

• Start the engine cold and listen for rattles or knocks.
• Watch the temperature gauge throughout the drive.
• Drive on full lock slowly to check for clunks from the transfer case.
• Feel for vibration through the steering under braking.
• Check that the car sits level at the rear.
• Read the fault memory with a diagnostic tool.

E53 X5: points to remember

The best E53 X5 is the one with the most complete service history and the least rust. Look for evidence of cooling system work, transfer case care and regular oil changes. A specialist inspection is always worth the cost on a car of this age, because it can reveal problems that a short test drive cannot.

Is the E53 X5 a good buy?

A well-maintained E53 X5 is a comfortable, capable and characterful SUV at a low price. The 3.0d and 3.0i are the safest choices, while the V8 models offer more performance for buyers who accept higher costs.

As values of good examples begin to rise, the E53 X5 is also becoming a modern classic. Buy the best car you can afford and keep up with maintenance.
