Modern car You can easily call the computer on wheels. This applies to Volkswagen cars. The self-diagnosis system informs the driver about any malfunction at the time of its appearance - on dashboard Errors with digital code are displayed. Timely decoding and elimination of these errors will help the car owner to avoid more serious trouble.

Computer diagnostics of cars Volkswagen

With the help of computer diagnostics, you can identify most of the faults volkswagen cars. First of all it concerns electronic systems cars. Moreover, timely diagnostics will be able to prevent possible breakdown.

Typically cars Volkswagen are diagnosed before buying on secondary market. However, experts recommend to diagnose even new cars at least twice a year. This will avoid many unpleasant surprises.

ERS signal on Volkswagen car dashboard

Often, failures in the work of individual car systems occur unnoticed for the driver. However, these failures may further provoke a more serious breakdown. The main features that should be paid to, even if malfunction signals do not light up on the dashboard:

• fuel consumption for unknown reasons increased almost twice;
• the engine began to tune, there were noticeable failures in its work both when the speed set and idling;
• began to often fail various fuses, sensors, etc.

If any of these features appear, you should immediately drive into the machine to the service center for diagnostics. Ignoring such situations will illuminate on the dashboard of the red window with a message about the engine malfunction, which is always accompanied by a code of five or six digits.

This is the ERS error, and the code indicates which system has failed.

Diagnostics

Total diagnosis

If you encountered defined faults or just want to check your EPC (engine control unit) for errors, then you will need to be diagnosed. To make it prepare a laptop, a special diagnostic adapter and adapter. Note: The VAG COM software must be installed on the laptop, without it, your AUDI check will be impossible. In addition, you may need an adapter with COM on USB if your computer is not equipped with the first port.

Software can be downloaded in free access on the Internet, but the adapter and the diagnostic adapter will have to buy. When everything is ready, you can proceed to the diagnosis:

1. To begin, install all the necessary drivers for the operation of the adapter. When the drivers are installed, the COM port should appear in the device manager of your laptop. Run "Start", and then right-click or touchpad click on the My Computer icon. Before you will display a window in which you need to click on "Properties". In the "Equipment" tab, you should select the "Device Manager" submenu. Here you can find the "Ports" tab. Click on it with the left mouse button and a small window with a list of adapters will open.
   Do not touch anything here, all the settings are in order. Click on the "Advanced" tab. A window will be displayed on the laptop screen, where you need to find a construction site "Use (Operation) FIFO buffers". Opposite this line there is a tick, you need to remove it. The port number itself must be no higher than the number "4", remember the exact number.
2. Now you need to find a diagnostic connector in your car. In older Audi models, it is located in a block with a relay that is under the hood. For more modern models The diagnostic connector is installed in the cabin. It must be under the steering wheel, closer to the driver's door. If yours car Audi. A4, A6 or C5, but you did not work out the connector, then try searching for it in the fuse box. Open the driver's door and with the end side of the torpedoes, remove the plastic cover behind which the fuse block is located. The connector must be or driving, or in this block.
3. When the diagnostic connector is found, you will need to connect to it. Connect the adapter through the adapter to the diagnostic connector and the laptop. The tester itself will also need to connect to the power. For this, the cigarette lighter is quite suitable.
4. Now take the laptop and start the utility on the EPC diagnostic and auto check for malfunctions. Having done this, check the key in the ignition lock. Opening the utility on the computer, go to the "functions" section (or "options").
5. Here you will need to specify the number of your COM port, which you have configured earlier and remembered. Specify the number and click on the Diagnostics button (or "Test", depending on the software version). If everything is done correctly, the window appears before you, as shown in the photo.
6. Now the left button of the touchpad or mouse click on "OK". After that, click on "Apply".
7. Go back to the main menu and click on the "Selection". After that, you can see a new window, in which certain controllers are specified according to the sections. Here you can distribute all at once or separately the engine, a transmission system, electronics, chassis, and so on. Click on the "engine".
8. When the controller is selected, the program will start connecting to the EPC. The engine control unit after a while will establish a connection with your tester. After a few minutes, you will appear in front of you, where the basic information will be specified directly about the controller.
9. To understand what problems are present in your Audi A4 vehicle, A6, or another brand, you will need to click on the "Troubleshooting" button (or "Problem Survey"). After that, the window will appear in front of you, in which all the breakdowns are indicated, which once recorded the EPC of your car.

If you click the "Clear Code" key, all error information will be erased, but if the combination appears again, it already speaks about the device breakdown.

Actually, now you need to decipher the combinations of the faults. In the event that the EPC of your Audi A4 or A6 signals a breakdown of certain sensors, it can not only speak about the failure of the device. It can talk about other failures in the system that influenced the functioning of the sensors. Either the problem may actually come to work in one of the sensors, and other error codes are a consequence of the element work incorrectly. In the event that the devices are really faulty, the diagnosis will tell you about it after you erase the memory.

When the work with the utility is complete, the ignition must be turned off. Then disconnect the cigarette lighter (or other nutrition from the tester). And now you can turn off the rest of the connectors.

Diagnostics Climate control

Climate control in cars A6 has the option of self-diagnostics. Depending on which version of the system your car is equipped, it can be from 61 diagnostic channels and more. To implement independent check Control climate, follow these steps:

1. Turn the ignition key. To check the system, it is optional to include. To start the diagnostics, press the airflow button up, as well as the air circulation button in the car. They must be clamped at the same time.
2. On the left screen, you will see the code 01C is the first channel number. To enter the channel, you need to press the circulation button again. At this point on the screen you will see the contents of the channel. That is, if there is an error, it will be shown here.
3. To get to the next channel, you must press the button "+" temperature. Accordingly, to return to the previous channel, click "-".

Decoding combinations

Now let's talk about decrypting the received fault codes.

Errors Climate Systems

Below are the most common combinations of errors that may occur when diagnosing the climate of the AUDI A6, A4 system and other similar models.

Fault sensors

Below are the main faults characteristic of auto sensors.

Other error codes

Unfortunately, we can not imagine everything without exception codes. In fact, there are several thousand them, so we will consider the most important and frequently found from them during the diagnosis.

Modern cars are equipped with flightcomputers, and when there are failures and errors in electronics, the driver sees the appropriate code on the dashboard.

Consider the main errors and their decoding on the example of Volkswagen Golf 4.

Why do I need computer diagnostics

Computer diagnostics allows you to identify most of the faults in the car. After all, the on-board computer constantly "scans" the condition of the car, tracks the normal functioning of internal processes.

This procedure is performed using special software on a laptop that connects to the wires to on-board computer Auto.

Even such a diagnosis refers to the obligatory procedures after the purchase of a used car from the hand.

And, of course, do not do without checking the owners of those Volkswagenov, on the dashboard of which the code or text warning caught fire or a textual error warning, or ePC signal.

Unfortunately, the flightcomputer itself can work well. And then about the fact that the diagnosis is needed, the owner will report a number of signs (They may not be accompanied by fault signals):

• seriously increased fuel consumption
• motor is unstable, poorly gaining speed, its troit
• fuses and sensors began to fail

If at least one of the listed features is needed, you need urgently go to the service center.

If you ignore this situation, sooner or later, a red window will appear on the dashboard with a message about the engine malfunction, plus a 5- or 6-digit digital code. This is EPC error.

Self-decoding EPC codes

Every time the display with EPC is turned on, the message is accompanied by a code that corresponds to a certain malfunction; They can be hundreds.

We list the most common mistakes faced by Volkswagen owners.

TOTAL

As we can see, the list of VOLKSWAGEN cars common on models is very wide. And in most cases, the help of a specialist and computer diagnostics is required to eliminate them.

And Ignoring individual errors (see notes) can lead to sad consequences.

• Read the most common automatic transmission errors and read their decoding.

• 4F81, 4F82, 4F83, 4F84, 4F85 - control of the gear ratio of individual couplings (in order A, B, C, D, E). They appear mainly due to combustion or strong wear of the friction clutch. When trying to switch to the next transmission, turns will be raped and, as a rule, care emergency mode. Often these errors appear with errors from paragraph 2.
• 4F87, 4F88, 4F89, 4F8A, 4F8B, 4F8C, 4F8D, 4F8E, 4F8F, 4F90, 4F91, 4F92, 4F93, 4F94, 4F95, 4F96, 4F97, 4F9B - control of the gear ratio during transmissions. These errors just as in paragraph 1, arise due to slipping when switching gear. The cause can be burnt or strongly worn friction clutches, worn by mechatronics (hydraulicock) and its electromagnetic valve (solenoids), or worn sliding sleeves.
• 4E84 - 4EE9 - error codes associated with the malfunction of electromagnetic valves and sensors. Most often arise due to internal electronic fault ACP control unit (located on the mechanical circuit board), less often with electrical malfunction of the chain of solenoids themselves.

Decryption and causes of the most common mistakes of Audi automatic transmission, Volkswagen, Skoda

The most popular fault codes are:

• P0729, P0730, P0731, P0732, P0733, P0734, P0735, P0736 (17113 - 17120) - improper gear ratio of individual gears (P0729 - 6th Transmission, P0730 - Total automatic transmission, P0731- P0735 - from 1st to 5 -The transfer, respectively). These errors are manifested as a result of slipping on certain transmissions. The cause is usually burnt friction clutches, problems with the hydraulic unit, the wear of the sealing elements of the friction couplings (characteristic of the automatic transmission 09G). Sometimes these errors are written together with errors P0780-P0784 (gear control).
• P0740, P0741 (17124, 17125) - Malfunction Couplings of the torque converter, there is no torque transmission. In this case, the problem most often consists in strong wear of the cluster of the torque converter. In motion, this problem can be expressed as a swing of revolutions (100-200 rpm) in partial load mode, deterioration of overclocking characteristics.
• P0746, P0747, P0748, P0749, P0750, P0751, P0752, P0753, P0756, P0757, P0758, P0761, P0762, P0763, P0766, P0768, P0771, P0773, P0776, P0777, P0778, P0779 (17130 - 17163) - Malfunctions In the electrical circuit of solenoid valves (solenoids). When these errors appear, the automatic transmission goes to the emergency mode (the entire control electronics is turned off). Causes of malfunction are usually in the electrical wiring and the electromagnetic valves themselves. It is less likely to cause a malfunction to be the ACAP ECU (VW Passat B5 +, Audi 97-04 Gg with ZF automatic transmission).
• P0705, P0706, P0707, P0708, P0710, P0711, P0712, P0713, P0714, P0715, P0716, P0717, P0720, P0721, P0722 (17089 - 17106) - malfunctions associated with the frequency sensors of the input and output shaft automatic transmission (G182, G195), Oil temperature sensor in automatic transmission (G93) and transmission sensor (inhibitor) (F125). On different models of the boxes, these problems are solved in different ways: from a simple replacement of sensors before replacing the metrapon block.

The most accurately to localize the problem and eliminate it will help you will help specialists of the VAG-service.

• 005981 P175D - coupling 1 unintently open (Clutch 1: Opens Unintentionally)
• 005999 P176F - Coupling 2 Unintentionally closed (Clutch 2: Closes Unintentionally)
• 005998 P176E - coupling 2 unintentionally open (Clutch 2: Opens Unintentionally)

These errors most often arise due to the malfunction of the electromagnetic valves of the mechatronics, the problem usually disappears after restarting the engine. Much less often they can be a consequence of clutch problems. To determine the cause, a parametric diagnosis is needed.

• 005925 - comparison of the speed of rotation of the output shaft of the KP from the sensors 1 and 2 - P1725 - an inaccurate signal
