Characteristics of Chassis and Steering Parts in BMW 5
When buying oil, don't forget to check the stickers on the gearboxes and differentials. This way, you can find out the required oil type.
If the car has a «dead clutch,» then it's better not to make such a purchase. Because when you change the clutch, you will also have to spend money on an expensive dual-mass flywheel.
With calm, even operation, the clutch can be left untouched until 200,000 km. In reality, the clutch service life is up to 100,000 kilometers.
Automatic transmissions also need to be diagnosed before purchasing the car.
Pay attention to the smooth operation of the gearbox, without jerks or jolts. It should shift gears imperceptibly.
Most automatic gearboxes have oil that will last for the entire service life of the cars. That is, it is not changed. This issue is always debated on forums. One side constantly argues with the other about oil changes.
Service centers also support the version that the oil needs to be changed after 80-100,000 km. Because it loses its qualities and becomes unsuitable. Friction linings wear out, which can lead to filter contamination. And this, in turn, threatens transmission failures.
Characteristics of Chassis and Steering Parts in BMW 5
Here:
intake manifolds;
electronic throttles and gas pedals;
other engine control units.
M62. These are V-shaped eight-cylinder engines, with working volumes of 3.5 for 530i, 4.4 for 540i. Initially, like in M52, the cylinders had coatings that were nickel-silicon at the beginning of production. They were also aluminum-silicon.
The latter are strong and reliable. They were not afraid of sulfur. In March 1997, the production facility switched to producing engines with aluminum-silicon cylinder coatings. The updated engines were labeled M62 TU, along with systems for changing the phase in gas distribution.
This mechanism is called Vanos.
The BMW 5 E39 engines began to work with revolutionary mechanisms at that time, which regulated the camshafts, serving to control the intake and exhaust valves.
These mechanisms allowed for increasing torque at low revs. In other words, the cars could accelerate almost from a standstill.
Single Vanos. It deals with regulating the intake valves.
Double Vanos. Regulates the exhaust valves for smooth power delivery, using almost the entire range of RPM. The first simple Vanos was on M52 and M62TU. Double — on M54 and M52TU. The downsides of this mechanism relate to repairs. With good maintenance, the service life can reach up to 250,000 kilometers. But here, the main role is played by oil. Or rather, its quality.
Because replacing the entire system as a whole will cost around $1000 or more. Repair kits may be offered for $40-60 (labor not included) to replace in a single-Vanos engine.
However, in some cases, repair kits do not help. Only replacement is necessary. If Vanos «dies,» the car will:
have poor traction, not reaching 3000 rpm;
have noise or knocking in the front parts of the engines;
have high fuel consumption.
M51S. M51TUS belong to diesel units. They have an injection pump. They have a working volume of 2.5 liters for 525tdc. They are reliable. Timing belts last from 200 to 250 thousand kilometers. Turbochargers also work. Repair may be needed only after 200,000 km. Repairing the injection pump is very expensive. After passing so many kilometers, repair of the engine management electronics may also be needed.
M57. Turbo diesel engines. They have direct fuel injection (Common Rail). The units have a working volume of 2.5 liters for 525d, 3.0 liters for 530d. The M57 engines are reliable and powerful compared to M51. But the diesel fuel must be of good quality.
Complex hydro support structures in the engines. They are very expensive. The most preferred options are 530d, with 184 hp M57, with 193 hp. M57TU. Before purchasing, everything must undergo diagnostics.
M47. These are the only four-cylinder engines in the BMW 5 E39. Units with working volumes of 2.0 liters for 520d.
They have:
turbines;
intercoolers;
Common Rail mechanisms.
They appeared with 136 hp after the redesign of M57.
Common Issues with All BMW E39 Engines
They have a weak cooling system. Therefore, if neglected, the engine will fail.
The main culprits of breakdowns are named:
electric units for auxiliary fans;
thermostats;
dirty radiators;
untimely coolant replacement;
ignition coils with non-OEM spark plugs.
Radiators need to be disassembled and cleaned at least once a year. If you have high mileage, this should be done twice a year. V8 engines cannot handle expansion tanks with cooling antifreeze. They crack. Cooling fans have an average life span of 5-6 years.
Ignition Coils
Non-OEM spark plugs do not like them. OEM ones are very expensive. And if you use our fuel, they will only last up to 40,000 miles. Coils cost around $60 each, and each cylinder should have one coil.
Lambda sensors or oxygen sensors also have problems, and this electronics becomes unserviceable. You need 4 pieces for 1 engine.
Air flow meters, crankshaft and camshaft position sensors can also be troublesome. To avoid these «hassles» in the form of breakdowns, make sure to thoroughly diagnose the car you are planning to buy.
Transmission of BMW 5 E39
If not for the human factor, the automatic and manual transmissions can be called reliable. The manual transmission is five-speed. The six-speed is only for M5 variants and some 540i.
After covering 15,000 km
plastic bushings of the gearshift levers start to rattle;
seals start to leak.
Manual gearboxes are serviced according to the schedule after 60,000 km. It is also when the oil is replaced in the differentials.

In the front optics. Cars with «angel eyes» headlights started to be produced.
Changes also affected the rear lights and turn signals.
Round shape was given to fog lights.
Moldings were given body-colored shades.
Decorative grilles for radiators were redesigned.
The design of the steering wheels started to feature the M style.
The bodies deserve praise for their corrosion resistance, but not for damage resistance. Restoring the metal is impossible.
Engines have also undergone innovations
In the engines of BMW 5 E39, the most optimal indicators are associated with a volume of 2.8 liters and 193 hp. When the facelift was carried out, they started using three-liter engines with 231 hp. The fuel and maintenance costs for 6-cylinder engines are the same. Therefore, two-liter BMW 5 E39 did not gain popularity.
The petrol engines in the 5 Series E39 are as follows:
M52. They represent a range of reliable, inline six-cylinder engines, with a displacement of 2.0 for 520i, 2.5 for 523i, and 2.8 for 528i. Only in 1999 did the engine units acquire repairable status. Until then, the engine cylinders had a nickel-silicon surface. The cylinder coatings couldn't withstand sulfur in gasoline and would deteriorate.
Therefore, they could not be repaired and restored. In 1998, thanks to modernization, the engines received cast-iron inserts (liners). Due to the modification, the engines were designated as M52 TU.
M54. Engines related to the facelift era. In R6 units, the working volumes are 2.2 for 520i, 2.5 for 525i, and 3.0 for 530i. They have more power compared to M52. The 2.5-liter M54 has 192 hp, while the 2.8-liter M52 has 193 hp.

Common Issues with All BMW E39 Engines
They have a weak cooling system. Therefore, if neglected, the engine will fail.
The main culprits of breakdowns are named:
electric units for auxiliary fans;
thermostats;
dirty radiators;
untimely coolant replacement;
ignition coils with non-OEM spark plugs.
Radiators need to be disassembled and cleaned at least once a year. If you have high mileage, this should be done twice a year. V8 engines cannot handle expansion tanks with cooling antifreeze. They crack. Cooling fans have an average life span of 5-6 years.
Ignition Coils
Non-OEM spark plugs do not like them. OEM ones are very expensive. And if you use our fuel, they will only last up to 40,000 miles. Coils cost around $60 each, and each cylinder should have one coil.
Lambda sensors or oxygen sensors also have problems, and this electronics becomes unserviceable. You need 4 pieces for 1 engine.
Air flow meters, crankshaft and camshaft position sensors can also be troublesome. To avoid these «hassles» in the form of breakdowns, make sure to thoroughly diagnose the car you are planning to buy.
Transmission of BMW 5 E39
If not for the human factor, the automatic and manual transmissions can be called reliable. The manual transmission is five-speed. The six-speed is only for M5 variants and some 540i.
After covering 15,000 km
plastic bushings of the gearshift levers start to rattle;

Manual gearboxes are serviced according to the schedule after 60,000 km. It is also when the oil is replaced in the differentials.
When buying oil, don't forget to check the stickers on the gearboxes and differentials. This way, you can find out the required oil type.
If the car has a «dead clutch,» then it's better not to make such a purchase. Because when you change the clutch, you will also have to spend money on an expensive dual-mass flywheel.
With calm, even operation, the clutch can be left untouched until 200,000 km. In reality, the clutch service life is up to 100,000 kilometers.
Automatic transmissions also need to be diagnosed before purchasing the car.
Pay attention to the smooth operation of the gearbox, without jerks or jolts. It should shift gears imperceptibly.
Most automatic gearboxes have oil that will last for the entire service life of the cars. That is, it is not changed. This issue is always debated on forums. One side constantly argues with the other about oil changes.
Service centers also support the version that the oil needs to be changed after 80-100,000 km. Because it loses its qualities and becomes unsuitable. Friction linings wear out, which can lead to filter contamination. And this, in turn, threatens transmission failures.

Characteristics of Chassis and Steering Parts in BMW 5

The BMW 5 Series E39 is the last in the BMW lineup. Many brand enthusiasts are delighted with the cool design, excellent handling, and atmospheric engines. The BMW 5 Series E39 started production in 1995. A facelift was carried out in 2000. Its production ceased in 2003. How does the design, handling, and engines fare?

The Bavarian manufacturer focused on driver's seats in the production of these cars. Although the cars themselves are large, the cabins are not as spacious.

But both passengers and tall drivers, up to 190 cm, feel comfortable. High-quality materials were used for the interior finishing. The assembly of cars was also done excellently. However, there were some misses with the door cards as they are most affected by external influences.

There is good sound insulation here. But if you want to hear music and conversations well in the car, you will need additional soundproofing materials.

The music system also desires improvement since it goes through cassette players or CD changers. There is no MP3 here, but you can install it for an additional cost.

In the basic equipment of BMW 5 E39 cars:

electric packages for mirrors and windows;
air conditioners;
6 airbags;
power steering;
anti-lock braking systems (ABS);
traction control systems (ASC+T);
Dynamic Stability Control systems (DSCIII)

Bavarian cars are also sold with additional equipment, for example, with dual-zone climate control.

After 2000, BMW 5 Series E39 saw changes.

M62. These are V-shaped eight-cylinder engines, with working volumes of 3.5 for 530i, 4.4 for 540i. Initially, like in M52, the cylinders had coatings that were nickel-silicon at the beginning of production. They were also aluminum-silicon.
The latter are strong and reliable. They were not afraid of sulfur. In March 1997, the production facility switched to producing engines with aluminum-silicon cylinder coatings. The updated engines were labeled M62 TU, along with systems for changing the phase in gas distribution.
This mechanism is called Vanos.
The BMW 5 E39 engines began to work with revolutionary mechanisms at that time, which regulated the camshafts, serving to control the intake and exhaust valves.
These mechanisms allowed for increasing torque at low revs. In other words, the cars could accelerate almost from a standstill.
Single Vanos. It deals with regulating the intake valves.
Double Vanos. Regulates the exhaust valves for smooth power delivery, using almost the entire range of RPM. The first simple Vanos was on M52 and M62TU. Double — on M54 and M52TU. The downsides of this mechanism relate to repairs. With good maintenance, the service life can reach up to 250,000 kilometers. But here, the main role is played by oil. Or rather, its quality.
Because replacing the entire system as a whole will cost around $1000 or more. Repair kits may be offered for $40-60 (labor not included) to replace in a single-Vanos engine.
However, in some cases, repair kits do not help. Only replacement is necessary. If Vanos «dies,» the car will:
have poor traction, not reaching 3000 rpm;
have noise or knocking in the front parts of the engines;
have high fuel consumption.

In the front optics. Cars with «angel eyes» headlights started to be produced.
Changes also affected the rear lights and turn signals.
Round shape was given to fog lights.
Moldings were given body-colored shades.
Decorative grilles for radiators were redesigned.
The design of the steering wheels started to feature the M style.
The bodies deserve praise for their corrosion resistance, but not for damage resistance. Restoring the metal is impossible.

Engines have also undergone innovations

In the engines of BMW 5 E39, the most optimal indicators are associated with a volume of 2.8 liters and 193 hp. When the facelift was carried out, they started using three-liter engines with 231 hp. The fuel and maintenance costs for 6-cylinder engines are the same. Therefore, two-liter BMW 5 E39 did not gain popularity.

The petrol engines in the 5 Series E39 are as follows:

M52. They represent a range of reliable, inline six-cylinder engines, with a displacement of 2.0 for 520i, 2.5 for 523i, and 2.8 for 528i. Only in 1999 did the engine units acquire repairable status. Until then, the engine cylinders had a nickel-silicon surface. The cylinder coatings couldn't withstand sulfur in gasoline and would deteriorate.

Therefore, they could not be repaired and restored. In 1998, thanks to modernization, the engines received cast-iron inserts (liners). Due to the modification, the engines were designated as M52 TU.

M54. Engines related to the facelift era. In R6 units, the working volumes are 2.2 for 520i, 2.5 for 525i, and 3.0 for 530i. They have more power compared to M52. The 2.5-liter M54 has 192 hp, while the 2.8-liter M52 has 193 hp.
