To take or not select a thoroughbred "German": disadvantages of the BMW X6 with a run
BMW X6 - one of the most popular premium crossovers, all over the world. Despite the high cost and the need to wait for its turn to buy from a month or more, most of the sales to date fall on new cars, and all, because many potential buyers of second-hand BMW X6, are afraid of possible expensive breakdowns. Today we will try to either confirm that the purchase of this car from the mileage in time will result in not a small penny or dispel this myth.
To the quality of the paint and corrosion resistance of the body there are no complaints, but nevertheless, some body elements require attention. So in particular, you need to carefully monitor the condition of the drainage system located near the windshield. The fact is that if it hammers, there is a high probability of flooding the main control unit with a car. Not famous for its quality and trapeze janitors, over time it begins to creak, to solve the problem should be replaced by a trapezoid. Also there is a grip on the reliability of the reservoir GUR (cracking), and the hose of the washer fluid on the tailgate glass (there is a leakage of liquid). And if the first drawback can be eliminated quickly and inexpensively, then for elimination of the second one you will have to shell out about 500 cu. (it is necessary to disassemble almost the entire interior). BMW X6 is completed with such power units - petrol 3.0 (306 hp), 4.4 (407 and 450 hp); diesel 3.0 (from 230 to 381 hp), and a hybrid of 4.4 (407 hp). Depending on how the engine and turbo control system is configured, each powerplant has its own index - 30, 35, 40, 50 and M50. Operational experience has shown that the most optimal option for the purchase of BMW X6 with mileage, will be a car with a diesel engine. This type of engine has a rather large resource and rarely causes the owners to complain, so buying a diesel X6, even with mileage under 200,000 km, this is not always a verdict. Often on this run owners face with the first investments in the power unit, as a rule, this is the replacement of the glow plugs. But only on the condition that the car was not refueled at a gas station with a dubious reputation. The most reliable among gasoline versions is a motor with a volume of 3.0. Its weakest point is the injection system (a high-pressure pump and injectors go out of action). Motor 4.4 in 2008 was awarded in Germany, the title of "Engine of the Year", But for our operating conditions it is absolutely not suitable. The fact is that the motor is very heavily temperature-loaded, and the oil channels have the property of rapidly coking (black oily deposits are formed in all channels), as a result, the turbine experiences not only a large load (heated to 700 ° C), but also oil starvation, which leads to its rapid wear. For the same reason, to 120,000 km the crank liners are rotated and the rings are laid, as a result, this results in oil consumption, up to 1 liter per 1000 km. On most of these engines to 150000 km capital is required, the cost, which is equal to the value of a good second-hand foreign car (in the informal service for repair will ask about 6000 USD.). If you want to buy a new engine, then you will have to pay about 20,000 USD for it. All the power units do not have an oil dipstick, so you can not check the level and condition of the oil yourself. You also need to know that the vehicle is not being run by mileage or time, as most cars do. X6 is equipped with a system that independently monitors when it is necessary to conduct maintenance and notify about this by an inscription on the instrument panel. That's only considering our operating conditions, this system is rarely notified (once in 20-25 thousand km). For Europe, such intervals are considered the norm, but not with us. Given the quality of combustible lubricants, this can result in disastrous consequences. Therefore, in order not to experiment, most servicemen recommend not to wait for notification from the system and to service the car no less than once in 10000 km. On cars of the first years of release, the problem with piezo-fogs is widespread (the cost of one fluctuates around 200 $). The main problem is that if even one nozzle fails, you will be strongly advised to change the whole kit. BMW X6 engines are very afraid of overheating, and because of the lack of an engine temperature sensor on the instrument, it is impossible to monitor its temperature. Therefore, it is necessary to wash the cooling radiator at least twice a year.
Officially BMW X6 comes only with a six- and eight-speed automatic transmission, there is also a mechanic, but it is only available on European versions. The reliability of automatic transmission differs greatly, and the point here is not that someone was lucky, but someone does not, and in the engine power and the more powerful it is, the earlier the repair of the box will be required. For example, with the most powerful motor 4.4, the box rarely lives more than 100,000 km. On diesel cars, problems with the box are less common, and if you do not neglect service intervals (changing oil and filters every 80,000 km), it will last up to 300,000 km. The main problems of automatic transmission are the failure of mechatronics, the wear of the bushes inside the box, the pallet of the box and the plug to which the electrical connector is connected begin to flow to the 60000 km. BMW X6 salon is made of very high-quality and wear-resistant materials that retain good market appearance even after 200,000 km . The only element of the cabin, along which you can determine the approximate range, is the stop / start button, which starts to blur at 150000 km, and on 200,000 km there are almost no inscriptions on it. No special complaints and noise insulation. I also want to note the reliability of electrical equipment, which is quite a large number. Of the shortcomings in electronics can be noted only the unreliability of the climate control system of the passenger compartment.
BMW X6 front and rear is equipped with an independent multi-link suspension. In top equipment, the car is equipped with a "X-Drive"With active steering and active rear differential. This combination gives an incredible control over the controllability of the car, which even many owners of the sport coupe will envy. But there is such a bundle and its drawbacks - the high cost of repair. Before buying a used BMW X6, be sure to check the airtightness of the differential, the fact is that in most cases oil flows out of its drive. The main sign of the problem is oil stains on the rear gearbox. Also pay attention to the status of active stabilizers. If the previous owner did not ride carefully, they would be in oily stains (the cost of one original stabilizer fluctuates between 800 and 1000 cu.). On the active stabilizers and power steering, one pump works, and in order not to change it to early runs, it is necessary to monitor the level and state of the GUR fluid. If we talk about the service life of the consumable suspension components, the stabilizer struts (on average 30-40,000 km on average) fail most often. Cross-arms on average will serve 60-70 thousand km, on the same run, it may be necessary to replace the steering rods. Silencers of longitudinal arms and ball bearings serve 80-90 thousand km. Shock absorbers, bearing and hub bearings are nursed to 150,000 km. Brake pads on average live 30-35 thousand km, disks up to 70,000 km. Despite the fact that the BMW X6 was formed as an unreliable car, it must be recognized that this car is quite reliable, and most of the problems faced by owners are the result of improper maintenance and operation. But it is necessary to recognize that the car has a number of minor deficiencies for the elimination of which not small investments are required. The best option would be a car with a diesel engine and a small run (up to 100,000 km) or a story familiar to you.
