P2872 ford focus


  • Dtc P2282 Ford Fiesta
  • In the modern automotive industry, successful copies are less and less produced, which for a long time are included in the ratings of the best-selling cars. This time let's talk about one of the few - Ford focus III. What is "Focus" of great popularity It is easy to guess from the name - this is the third generation of the model, produced since Available in all the most popular bodies: sedan, hatchback, station wagon.

    Generation 3 has several engine options. The main ones are: 1. There were diesel options, but this type did not take root in Russia. This is probably due to the poor quality of diesel fuel and expensive service fuel system.

    Gearboxes for "Focus 3" are available mechanical 5 and 6-speed and robotic "six-speed". In terms of comfort, the car of the new generation has become better. Convenient options are now available such as heated steering wheel, parallel parking assistance, automatic deceleration to the vehicle in front, tire pressure monitoring and even lane control with traffic sign recognition.

    Unlike classmates, the car boasts excellent handling on the road thanks to a non-standard solution rear suspension A MacPherson strut is installed at the front, and an improved Control Blade multi-link suspension is installed at the rear. It provides the driver with a very clear feedback , allowing you to predict the behavior of the machine on all types of surfaces.

    When Ford's all tricks run out Undoubtedly, the car came out good, even slightly better than classmates in some respects. But, as a rule, "the devil is in the details. Cramped interior for tall. WITH prestarting heating The internal combustion engine must constantly monitor the battery charge. A full discharge may occur and it will not be enough to start the engine.

    Tall drivers cannot comfortably adjust the seat without hitting people sitting on back row seats. As a result, either the driver is comfortable, but the passengers rest their knees on the back, or vice versa. In addition, people note small trunks. For the sedan version it is liters, for the hatchback - only liters. The ground clearance also displeases the owners - it is mm. You have to be afraid of every curb.

    But these are not the most serious flaws. The owner of "Focus 3", 1. You can forget about dynamic maneuvers. Overtaking on the highway is unrealistically difficult, even AvtoVAZs overtake in the city. I had to take it with an engine for horses. If you refer to the documentation, then this motor is characterized by acceleration to "hundreds" in For example: "Lada Priora" 1.

    By typical breakdowns and malfunctions, owners most often complain about short-lived steering racks. Even on a new spare part after 7 thousand kilometers, there is a slight knock when turning the steering wheel.

    It will not be possible to completely eliminate the problem; soon the rake will again remind of itself. It's all the fault of the plastic sleeve of the steering shaft. Some craftsmen grind a steel sleeve instead of a plastic one. This increases the interval between repairs by several times. The robotic box is extremely unreliable. The first problems can occur already at 90 thousand run.

    And then - more. Clutches with clutches, a clamping fork, a control unit are being repaired Some owners of thousand decide that it is cheaper to change the "robot" as a whole than to think about repairing it. Someone resorts to a more radical solution - to sell a car with a "robot" and buy something else.

    But the manual transmission also has its flaws. At one time, there was a factory defect on the early versions of the car. The oil seal in the box wore out quickly and oil leaked. Installing a new oil seal did not guarantee trouble-free operation.

    Every thousand I had to pay attention to this moment. In new versions, this problem has been eliminated. Here in the piggy bank we add stabilizer bushings creaking in winter and poor fit of the plastic interior parts during assembly.

    Without outside interference, the interior starts to creak. It is important that some parts are available only on request and are not as easy to change as, for example, suspension elements. This will almost certainly be an empty package. For something more comfortable to drive, for example, with a 2. The new "Focus 3", onwards, from the salon will cost from thousand rubles for an average configuration. What used Fords hide Over the past 24 hours, cars of all generations of Ford Focus.

    The vast majority have had at least one road accident. Out of 30 selectively viewed reports: 19 has an accident or insurance calculations; 5 cars have unpaid fines. Some cars have been involved in 2 or more accidents. Like this one: The car has 5 accidents recorded in 4 years. Accidents occurred at intervals of months. By itself, the number of accidents is not as bad as the amount of damage received in each of them. Having looked through the calculations of insurance companies for restoration work, we notice the most "expensive" accident case - for thousand rubles of damage.

    The car hit hard. Despite all the disadvantages, the Ford Focus III turned out to be successful and was able to find its buyer. Stylish, fashionable car came to taste, first of all, the young generation of motorists.

    Aggressive design and excellent handling spurs drivers to an active driving style. Unfortunately, sometimes this leads to sad consequences in the form of fines or accidents. And when selling, neither one nor the other the owners do not like to show. What fashionable and youthful cars would you like to read a review about?

    Write your options in the comments. Robotic dual-clutch transmissions are not a manufacturer conspiracy. This is an attempt to combine all the advantages of a classic automatic machine and mechanics in one unit. From the first, the preselective "robots" got everyday comfort, from the second - the overall efficiency and relative cheapness of manufacturing.

    As a bonus, the owner gets a high speed of step change, and most importantly - the continuity of the thrust flow. Whoever has tried it understands, and whoever has not had a headache with a "robot" will never give it up! The preselective gearbox is installed on almost all modern Ford models , but today we will talk about the most problematic version of the 6DCT - with "dry" clutches. Today it can only be found in conjunction with a 1.

    After restyling, the role of the flagship engine was taken by a 1. Here is how the manufacturer describes the work of the Powershift robotic gearbox at Focus: This modern 6-speed automatic transmission combines the convenience of an automatic transmission with the efficiency of a manual one.

    PowerShift preselects the next gear to avoid loss of power when shifting. With this automatic gearbox, you can change gears quickly and smoothly, reducing fuel consumption and CO2 emissions.

    From Ford marketing materials. Everything sounds beautiful in press releases, but in reality? But in fact, the owners of Ford Focus III generation have earned so much trouble on their neck that they are just right to become related with the owners of fragile copies of the DSG! Thousands of angry posts on the club forums about breakdowns, hundreds of appeals to the Russian representative office of Ford - the scale of the problems with Powershift is amazing.

    This "robot" has several sores at once, but the symptoms are the same - jerks and vibrations when switching and starting, as well as the transition of the box to emergency mode. The most common diagnosis is a profuse leak of the input shaft oil seals, as a result of which transmission oil hits the clutches, causing them to slip.

    Trouble can happen regardless of the mileage - at least 5,, at least 50, km. Often the clutch forks jam - there are naturally two of them at Powershift. The problem is solved by replacing the clutch, forks and oil seals new model. A lot of trouble is also caused by the TCM module with executive electric motors, which is responsible for shifting gears and squeezing the clutches.

    There is also no other control for a faulty manual transmission control unit, except for a replacement with an improved unit. The saddest thing is that these defects could fall on the head of the "trick" not only individually and in different combinations, but also in one magnificent bouquet! AvtoVesti simply could not pass by without understanding the real cost of repairing the "robot" Powershift.

    We took the most difficult case and this, believe me, is not uncommon , when in one order or another it is necessary to eliminate all the above malfunctions, and turned to the official Ford dealers in Moscow. Here's what happened in the end: a set of two new original clutches costs 86, rubles, for large and small forks actuators for engaging the clutches, you will have to pay 67, rubles, and the TCM control module costs 48, rubles. Let's add 1, rubles here for new input shaft oil seals and another 17, rubles for work on replacing problem parts.

Let's add 1, rubles here for new input shaft oil seals and another 17, rubles for work on replacing problem parts. All together - rubles! An absolutely shocking figure for owners of relatively budget Ford Focus Spare parts Installation work The situation is, of course, frightening, but not always fatal.

    At first, Ford company Sollers is well aware of Powershift weaknesses and has already undertaken work on upgrading problematic parts. If the "robot" breaks down, official dealers promptly carry out repairs and change the necessary spare parts within the framework of the warranty. Secondly, the manufacturer has an extended warranty program, when for a certain amount warranty obligations Ford is expanding for a certain period of time we recommend using this service for the owners of those Focus copies for which the box has not yet been repaired.

    And if, when choosing a Ford Focus III on the secondary, you should still be more vigilant, then new cars after restyling with the Powershift "robot" seem to be more or less easy to buy. At the very least, the manufacturer swears that the number of complaints about the box for such machines is practically reduced to zero.

    Gold 1 million box on the Getrag conveyor Transmission manufacturer Getrag has formed a joint venture with FoMoCo Ford Motor Company to produce preselective dual-clutch transmissions. DSG works harder, with a slight jerk at the start and a well-felt engine braking under the throttle. With PowerShift, shifting is softer, almost like a classic hydromechanical automatic, but you can effectively brake the motor only in manual mode Ford Focus 3 is equipped with 3 types of transmissions: manual transmission, automatic transmission with a torque converter, robot ff3 Powershift dry 6DCT and wet 6DCT for diesel versions.

    They combine the convenience of a conventional automatic transmission with the performance and high level of efficiency of manual transmissions.

    As usual, Getrag declares that the 6DCT is filled with oil for life. But it is still worth changing to avoid problems ahead of time. Also DPS6 can be used in a hybrid drive combined with an electric motor. Efficiency is increased. Filled with oil and sealed for life design life 10 years orkmdoes not require periodic maintenance. Has a dry weight of 73 kg Faster gear changes and lower transmission losses. Electro-mechanical actuators eliminate the need for hydraulic lines.

    What Powershift 6DCT consists of: As mentioned earlier, the DPS6 is mechanically composed of 2 mechanical boxes that interact using electrical equipment and electronics. Dual clutches and dual input shafts There are 2 input shafts, one is hollow blue and the other is solid yellow and sits coaxially inside the hollow shaft.

    The inner shaft yellow has fixed gears for gears 1, 3, and 5; while the outer shaft blue has fixed gears for 2, 4, 6 and vice versa. Note that this shaft only has 2 gears, each of which is used for two gears. Each of these shafts is connected to a coupling via splines on the outside of the shaft. This arrangement provides a compact package for both couplings.

    Unlike other clutches seen in manual transmissions, normal condition at rest, the clutch is held by springs i. Output shafts The transmission has two output shafts shown in blue. Contrary to initial considerations, they do not carry gears that match the input shafts. Instead, the gears they carry are determined by the order of the selector forks. The gears on the output shafts are not fixed, but are free.

    Like the manual transmission, they are equipped with synchronizers to match the speeds and lock the gears. Gears 1, 3,4, 5, 6 and reverse are equipped with one synchromesh, while gear 2 is double syncronized. The second gear is connected to the rear gear on the same shaft although both can rotate freely, they do it together. Note that the orange reverse gears on both output shafts are directly connected to each other.

    However, they do not interact with either the yellow or blue input shafts. As a result, the output shafts and input shafts are not in the same plane - they are instead located in a triangular formation. Differential Both output shafts transmit torque through the output gear to a common differential shaft green. This differential is not in the same plane as the output shafts, it is biased again - 4 shafts are arranged in a parallelogram shape.

    A differential serves the same purpose as a mechanically equipped vehicle - it allows each of the driven wheels to rotate at a different speed for example, when cornering. Synchronizer sleeves and selector forks When discussing the output shafts, it was mentioned that none of the gears are attached to the shafts, but instead rotates freely. There are 4 synchronizers and matching assemblies that allow these freely rotating gears to match the output shaft speed and lock the gears.

    Each of these synchronizer sleeves has a corresponding shift fork that can move the sleeve to either side to lock the gear or in the middle to unlock the gear. Up to this point, the components that have been considered are all familiar, as they closely resemble manual transmissions - rather, two gearbox, since we have two clutches, two input shafts and two output shafts.

    Only with a differential, both of these units are combined into one output. Shear drives actuators For now, we need to focus on the two electric motors present in the TCM as they provide rotary output from the TCM to drive the selector forks.

    The motors are of DC brushless design. They have built-in Hall sensors to determine the position of the rotor and count the number of rotations it has traveled. These rotating selector drums pass through a spur gear system at a specific angle the range of travel for these drums is degrees. The side switches have a slot cut into them. The selector fork has a tab that is located in this socket.

    The slot is angled to the ends of the stroke so that when the selector lever is rotated, the tab is forced perpendicular to the direction of rotation i. If this is confusing, to understand it, imagine how a screw converts the rotational motion of the screwdriver into a straight motion.

    Thereby rotational motion generated by electric motors can be converted into moving selector forks back and forth This allows the selector forks to move the synchroniser hubs forward or backward to lock and unlock certain gears. For comparison, in mechanical box gears, the selector forks are manually operated using the gear shift levers. Clutch actuators Like a shift actuator, a clutch actuator converts electric motor movement into lateral movement.

    And again, a brushless DC motor is used. As previously mentioned, the clutch is held open by spring pressure by default and does not transmit torque. To close the clutch, the motor rotates a worm gear, which pushes the clutch actuator. A holding current is applied to the motor to keep the clutch closed.

    The following 2 animated images are a representative representation of how each of the clutches works. V DSG principle the same. We brake until the car stops in a period of seconds. Repeat exercise 1 5 times. Exercise 2. Shift gears in the order of, We keep the speed level at least for 2 minutes.

    Repeat the exercise 1 more time. Manufacturer's recommendations Ford Focus on the operation of the automatic transmission PowerShift. In positions R, D, S, the foot brake must not be pressed for more than 40 seconds.

    Do not forget to raise the handbrake. It is prohibited to tow a faulty car when the backstage position is P. Automatic transmission software reset The procedure is performed using specialized programs. After that, you need to perform adaptation exercises similar to those described at the beginning of the article. Exercise 1 We move smoothly and pick up acceleration up to 4th gear, without jerking. We continue to accelerate to 6th gear. We slow down smoothly until the car stops. Without turning off the engine, keep your foot on the brake pedal for 10 s.

    Repeat 10 times. We manually switch to 5th gear. Engage 4th gear manually. Repeat exercise 2 6 times. In this case, the selector is in the drive and parking positions for at least 5 seconds.

    If, after the procedures, the car twitches slightly, this is a normal reaction that will subside over time. If the twitching persists, the help of a specialized service station is needed diagnostics at the stand. Gold 1 million box on the Getrag conveyor Transmission manufacturer Getrag has formed a joint venture with FoMoCo Ford Motor Company to produce preselective dual-clutch transmissions.

    DSG works harder, with a slight jerk at the start and a well-felt engine braking under the throttle. With PowerShift, shifting is softer, almost like a classic hydromechanical automatic, but you can effectively brake the motor only in manual mode.

    If we take the Focus specifically, then the model face spoof detection github android a 1. In general, the 6F family is a reliable and comfortable automatic transmission with 6 gears by modern standards.

    Differ from previous generations American 4-speed automatic transmissions in that preventive repair and cleaning of the system is required a little earlier, and, like most modern economical automatic transmissions, does not like aggressive driving.

    Unlike the GM 6T series, the 6F series is tuned for a less dynamic and more gentle automatic transmission program. Ford regularly updates the automatic transmission ECU firmware, basically all updates are aimed at cutting down on drive and preserving the valve body and torque converter.

    Sincesignificant changes have been made to the design of the hydraulic and electrical parts, as well as expendable materials For example, the filter was made entirely of plastic, but retaining the double felt membrane. Better to change more often. The filter is disposable and should be changed with every oil change. The oil change period strongly depends on the operating conditions. When driving quietly on the highway, the first oil change may be needed after about thousand kilometers.

    But after prolonged loads near the limiting torque at low speedsin the city side, an oil change may be required after 20 thousand km. In general, as usual, on average, once every 60 thousand km. It is also worth preemptively repairing the torque converter without waiting for it to fail about thousand km. The more aggressive the driving, the faster the clutch is consumed. The entire 6F series is capricious to the oil level, does not have a dipstick and the oil level is checked using the overflow plug.

    And like all modern front-wheel drive boxes, it does not like loads with cold oil. Winter warming up of the checkpoint before driving is strictly recommended.

    Full cycle repair without third-party contractors: torque converter own workshopvalve body. In the presence of repair and contract automatic transmissions of the 6F series, as well as spare parts for them. We have been working since They combine the convenience of a conventional automatic transmission with the performance and high level of efficiency of manual transmissions.

    As usual, Getrag declares that 6DCT is filled with oil for life. But it is still worth changing to avoid problems ahead of time. The 6-speed 6DCT transmission has been developed for front-wheel drive-transverse configuration in the compact segment and is rated for torque up to Nm. Also DPS6 can be used in a hybrid drive combined with an electric motor. Efficiency is increased. Filled with oil and sealed for life design life 10 years orkmdoes not require periodic maintenance.

    Unlike other clutches seen in manual transmissions, in normal rest the clutch is held by springs i. The transmitting electronics ensures that only one clutch is closed at any time. Output shafts The transmission has two output shafts shown in blue. Contrary to initial considerations, they do not carry gears that match the input shafts. Instead, the gears they carry are determined by the order of the selector forks. The gears on the output shafts are not fixed, but are free.

A holding current is applied to the motor to keep the clutch closed. The following 2 animated images are a representative representation of how each of the clutches works.

    In DSG, the principle is the same. A little higher in the picture, which has input connectors from the ECU. The opposite side of this has the output of the 2 motors we saw earlier. The TCM collects input signals from various sensors, evaluates the input, and controls the drives accordingly. Vehicle speed Engine speed and engine torque Throttle position Ambient temperature to determine how viscous a gear oil is for cold starts Steering wheel angle to avoid overloading or underdrive when cornering Brake inputs Input shaft speed for both input shafts Ratio tilt of vehicle from body control module BCM The TCM controls the actuator motors with open loop control to provide adaptive control.

    This allows the TCM to identify and adapt to the following: Clutch engagement points F1 fans will hear about "clutch bite point" Coefficient of friction of adhesion Position of each synchronizer assembly The information for the above is stored in non-volatile RAM in the TCM. This is what constitutes the transmission-specific control models studied.

    These are only "requests" because the TCM will evaluate this against the other inputs prior to gear shifting - for example, it prevents upshifts to avoid hitting the cutoff Parking mode P Parking mode A parking lot is fixed on the output shaft so that the output shaft does not rotate.

    The latch pin is spring loaded to ensure that it does not jump out if not disconnected. Both clutches are not actuated, so they both open automatically. Shift drives lock gears 1 and R - since pulling the car out of P will cause one of these gears to be selected. The owner's manual also recommends installing a parking brake handbrake to ensure that this mechanism does not take all the load off the vehicle eg on a slope.
