Review

The design of the fourth seven BMW series E65 liked few. The general outlines of the next fifth generation BMW 7 remained the same, but the new executive sedan began to look noticeably more elegant and natural.

Inside, as befits a premium liner, everything is noble and rich. The quality of the finish is at its best. The dashboard is traditionally laconic. Comfortable seats allow you to survive many hours of travel without a hint of fatigue.

The basic version provides six airbags, electric front seats, dual-zone climate control and bixenon headlights. In a cramped parking lot will help the front and rear parking sensors. Door closers, electric trunk lid, front and rear view cameras, projection on the windshield and much more remained in the huge list of options that allow you to complete the car for your needs.

In addition to the usual version of the F01, an extended F02 was offered - with a wheelbase increased by 14 cm. Her choice is a matter of personal preference. The L-version provides more legroom for the rear passengers and a rear air suspension.

In 2012, the Bavarian seven survived restyling. External changes were cosmetic in nature – affected the bumper and optics. In 2015, there was another generational change.

Engines

BMW premium is one of the pioneers of downsizing. So, under the designation 750i hides 8-cylinder biturbo with a volume of 4.4 liters and a capacity of 408 (449 hp after restyling). The engine accelerates the large sedan to 100 km/h in just 5.2 seconds. This version is the most common in the secondary market. Under the hood of the 740i is located inline 3-liter six N54, cheered up by two turbines to 326 hp. After restyling, the N55 (320 hp) was used - the same R6, but with one twin-chamber turbine and Valvetronic's intake valve lifting system. But the top 6-liter biturbo fully corresponds to the index on the trunk - 760 Li. 12-cylinder N74 produces 544 hp. and 750 Nm of torque. The combination of 730i and 730d is not hidden. In the first case, you will find a 3-liter gasoline atmospheric N52 recoil 258 hp, and in the second - a 3-liter turbodiesel N57 with a productivity of 245 hp. The designations 740d and 750d are the same marketing math. It implies a 6-cylinder N57 turbo diesel combined with two and three turbochargers respectively. The most problematic is the BMW 750i with the N63 engine. In the collapse of the block are two turbochargers, two exhaust collectors and two catalytic converters. All this stuff is very "frying." As a result, the engine turned out to be too heat-loaded. As a result, the oil caps after 50-100 thousand km turn into plastic and begin to pass the oil. From excess oil, the valves are contaminated, and piston rings lie. Oil consumption increases to 1-1.5 liters per 1,000 km.

Transmission

The engines were combined with the 6- and 8-speed automatic transmission ZF. 8-speed automatic transmission became mandatory after restyling. Until 2012, it was used in the 760i, 760Li and 740d xDrive versions.

In both boxes, it is recommended to change the oil every 40-60 thousand km (15-18 thousand rubles). Problems with automatic transmission occur after 100-150 thousand km. Most often, mechatronics fail. For its repair will need 20-60 thousand rubles. If you do not update the oil, then soon the replacement may require a hydrotransformer, a set of frictions, a set of bushes and gaskets - more than 100,000 rubles.

F01/F02 was the first seven with all-wheel drive. Until that time, BMW had a traditional approach: a luxury sedan can only be rear-wheel drive. The xDrive system to reduce understeering distributes torque between the axles in the range from 40:60 to 20:80. In critical situations (in case of loss of contact of the wheels with the surface), up to 100% of the thrust can be sent to any of the axles.

After 100,000 km, the elastic clutch of the driveshaft often wears out (4000 rubles). On all-wheel drive versions after 100,000 km, the external SRUS of the front half-axles sometimes begin to crunch. The cost of the drive in the collection is about 30,000 rubles.

Walking

The 5-meter sedan received optional active integrated steering. The system completes the front wheels, and also knows how to turn the rear wheels at low speeds in the opposite direction to the front, and at higher - in the same direction. In practice, this reduces the steering wheel angle and improves maneuverability. When driving a car, you forget about the weight and the size. In xDrive cars, integrated steering was not offered.

In the extended version of the BMW F02 on the rear axle installed air suspension - basic equipment. The rest use adaptive shock absorbers with steel springs.

In terms of driving performance, the BMW 7 Series balances on the imaginary border between “sport” and “comfort”. The car hardly notices the “little things” on the road.

The levers of the front suspension have to be changed after 60-100 thousand km. The front springs can break after 150-200 thousand km. The cost of the original spring is about 7 000 rubles.

Sometimes the pump fails GUR - begins to buzz or leak. Faults of the pump are more common in cars with active steering and diesel engine. The cost of the new pump is 56 000 rubles, but repair is possible - about 20 000 rubles.

Some owners after 50-100 thousand km faced with an outside knock in the steering. Someone helped to replace the lower section of the steering shaft, and someone - the replacement of the steering rack. But some even after updating the steering components were unable to eliminate the knock.

Other problems and malfunctions

The corrosion resistance of the BMW F01 body iron does not raise any questions.

In the cold, the front doors may stop opening/closing. The reason is the ingress of moisture under the shirt of the cable connecting the handles to the lock.

The electrician often fails. As a rule, everything can be solved by banal disconnection of the terminal for a while. If a simple reception does not help, then perhaps the battery is already a little discharged - the electronics are capricious to the voltage in the onboard network. After 150-200 thousand km, a generator may require bulkheading.

Often, the battery discharges the outdoor door handle of the optional comfortable access system that has failed. These hands are broken (short) often. It costs 25,000 rubles.

Can also sway the light control unit FRM. He can be brought back to life after reflashing or soldering.

Over time, the front seats are heated. The heating element changes only in the collection with a mat to which the leather upholstery is glued. The cost of such a detail is about 70 000 rubles. Sometimes it is possible to do with low blood - the place of the wiring break is restored.

After 100-150 thousand km no-no and noise fan heater (from 7000 rubles).

Engines

• The most problematic is the BMW 750i with the N63 engine.
• Motorists recommend, without waiting for problems, preventively change the oil caps every 80-120 thousand km.
• rubles, as it is necessary to remove the engine and throw off the heads of the block.
• If you ignore the oil and gas, then after 100,000 km it is easy to get to overhaul (more than 300-400 thousand rubles).
• An example of this is the “seven hundred and fifty”, which traveled over 150,000 km without the problems mentioned above.
• In the top N74 (760i), catalysts and turbines are removed from the block, so there are no problems caused by excessive heat load.
• To do this, you need to remove the engine, but some masters perform the operation without dismantling the engine.

Transmission

• In both boxes, it is recommended to change the oil every 40-60 thousand km (15-18 thousand rubles).

• Over time, the front seats are heated.

The fifth-generation BMW 7 is a relatively common model in the secondary market. And some offers are bribed by an attractive price. But be careful. The car is technically very complex, and the electronics are capricious. In addition to the problem N63 sometimes throws surprises and machine. Maintenance and maintenance of a large German sedan will be very expensive. This is without taking into account the transport tax.
