What is the reason why the Audi A6 instrument gear indicator does not light up?

The Audi A6L gear indicator is not lit, generally speaking, the possible reasons are gear switch failure, PCM failure, transmission internal failure and gear light module failure.

Maybe the gear sensor is not good.

If the instrument indicator is not lit, first check the power supply fuse of the dashboard, and replace it if it is blown. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The lamp of the dashboard is damaged and needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there is an open circuit or short circuit, which will also cause the car dashboard to not light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00,000km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round bar to extinguish the indicator light of the timing toothed belt.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

If the indicator light (below) is on, then the bulb is damaged. The displayed driving guide prompts the reasons and possible measures. If the fault report continues to be displayed, please take the vehicle to a professional company as soon as possible to troubleshoot.

Audi adaptive headlights: malfunction!

Adaptive lights are no longer functional. The low beam is still working as usual. Please take the car to a professional company for troubleshooting.

Please take the car to a professional company for troubleshooting.

Headlight Assist: Fault!

You can manually turn the high beams on and off as usual. Please take the car to a professional company for troubleshooting.

Headlight Assist: Not currently available. The camera's field of view is limited due to environmental influences.

If the camera is blocked, then the driving guide will appear. The system shuts down automatically. Please try to turn the systems back on later.

Automatic headlights: malfunction!

The light and rain sensors have lost their function. For safety reasons, the low beam is continuously turned on when the lights are in auto. Please take the car to a professional company for troubleshooting.

The reasons may be as follows:

Audi A6 headlamps are all made of four-lamp system, and the main reason for the failure of this four-lamp system of car headlights is generally the use of over-power bulbs caused by failure.

Of course, there are also many car owners who buy some poor-quality bulbs on the market to replace, resulting in insufficient wattage; There are also some deliberate changes to high-power bulbs in order to make the headlamp have a larger wattage and stronger luminosity; These are all causes of car headlight failure.

These causes of car headlamp failure are basically improper use of light bulbs. Some car owners may not be concerned about this, but the fact is: these practices will lead to damage to other parts of the car.

For example, the lights are burned out, the battery is damaged, and more seriously, it may lead to a short circuit in the wire and cause the car**; Therefore, we need to take the failure of the car headlamp seriously to prevent accidents.

Maintenance method: Checking the burnout of the bulb of the Audi A6 exterior lamp is an extremely quick and simple job, but the comprehensive and systematic maintenance of the Audi A6 exterior lamp is not so simple.

Timely maintenance of the exterior luminaires of the Audi A6 is crucial for the driver, as it not only affects the comfort of the car, but also has a direct bearing on driving safety. Often, it is difficult for car owners to realize that their headlights, taillights, turn signals or parking lights are no longer working properly until they are reminded.

Incidentally, replacing a burned-out bulb is a simple job, and the DIY cost is less than what a repair station charges for lighting system maintenance.

More often than not, the failure of the lamp is not limited to minor problems such as burnt out bulbs, rusted sockets or damaged plugs, and often requires professional diagnostic techniques to analyze the root cause of the failure. Even for those low-priced cars, the interior and exterior lights are controlled by a host computer.

In addition, it is necessary to check the Audi A6 headlamp for cracks, because although surface cracks do not affect the lighting performance of the headlights, moisture will seep into the lamp along the cracks, which will inevitably reduce the life of the bulb.

The alignment of the headlight direction should also be included in the list of maintenance items, because in order to ensure maximum safety for the driver, the headlights must be able to provide good forward illumination for the moving vehicle. In addition to grasping the key, don't forget to check other light systems, such as turn signals, license plate lights, width indicators, parking lights, reversing lights, and brake lights.

In addition, many vehicles also have fog lights as standard equipment or popular options, fog lights are generally installed in a lower position on the car, so they are highly susceptible to stone damage, and when maintaining them, in addition to checking the lighting system itself, cracks in the lights should not be ignored.

First of all, the Audi A6L left headlights, small lights, fog lights, and turn signals are not the same road insurance, and the possibility of 4 road insurance burning at the same time is extremely low; Most likely, the left light tie-up iron is loose, causing a broken circuit; It is also possible that there is a problem with the lighting control module; Either there is a problem with the combination switch, or there is a problem with the communication between the two.

Is it that both sides are not lit? If it's one side, it might be a bulb, if it's two, it might be a line, or it might be a bad relay.

Audi A6 gear indicator flashing, indicating that there is a lack of transmission oil Bi Lao, add enough transmission oil indicator light to eliminate, the specific operation steps are as follows:

1. Open the door on the cab side of the Audi A6.

2. Pull the hood switch on the driver's left side of the driver's leg of the Audi A6.

3. Lift the hood of the Audi A6 engine upwards.

Fourth, use the support rod to support the engine hood of the Audi A6, to ensure that the support is firm, to avoid danger during operation.

Fifth, the supplementary provisions of the loose transmission oil to the middle of the upper scale line and the lower scale line can be.

Summary. Usually, a single headlight does not turn on, mostly because the bulb burns out. If two do not light up at the same time, it may be that the fuse is burned out, or the bulb is burned out at the same time, or it may be that the lamp wire is aging and broken or the terminal is loose, but the probability of these two phenomena is extremely small.

The following is a relevant introduction: 1. The principle of not lighting while lighting up: usually the left headlight, all the bulbs share a tie point, and the right side is also, if the left tie is bad, the current can only pass through other bulbs to the right headlight when the headlight is turned on, and then the right headlight bulb is then iron, at this time, you will find that the left headlight is bright but not very bright, this is because the current that is only used to light the left headlamp can not be used to take the iron normally, can only pass through other bulbs to the other end of the iron, the resistance value is large, the current is small, so all bright, But none of them are very bright.

2. The principle of the turn signal: control the flasher through the turn signal switch and tie the iron through the left or right turn bulb, so that the flasher can work. Before that, due to the lap failure, the turn signal bulb was already electrified, so the flasher did not work.

Audi A6L left headlight does not light up malfunction.

Hello! I am your automotive consultant, a special guest teacher, and the cumulative service has exceeded 10,000 people.

Hello, glad to answer your questions. I've seen your question, I'm typing the answer, it takes a little time to type, please wait! 

Where is the left headlight fuse.

Usually, a single headlight does not turn on, mostly because the bulb burns out. If two do not light up at the same time, it may be that the fuse is burned out, or the bulb is burned out at the same time, or it may be that the lamp wire is aging and broken or the terminal is loose, but the probability of these two phenomena is extremely small. Here's how it goes:

1. The principle of not lighting up while lighting: usually the left headlight, all the bulbs share a tie point, the right side is also, if the left tie is bad, when the headlight is turned on, the current can only pass through other bulbs to the right headlight, and then the right headlight bulb is then hit, at this time you will find that the left headlight is bright but not very bright, this is because the current that is only used to light the left headlamp can not be used to tie the iron normally, can only pass through other bulbs to the other end of the iron, the resistance value is large, the current is small, so all bright, but not very bright. 2. The principle of turn signal:

Control the flasher via the turn signal switch to catch the iron through the left or right turn bulb so that the flasher can work. Before that, due to the lap failure, the turn signal bulb was already electrified, so the flasher did not work.

Problems with the PC version. If you want to solve the problem, either you upgrade the computer board with this gearbox loss, or you can solve this problem by replacing it with a megabyte. This is a common question that asks people to have a lot of questions, and it is a common problem.

Expensive or not. If the computer version of the gearbox is upgraded, the cost is 200 yuan, and the replacement and maintenance are done jujubes, ** must be in Zenyu This He Huyan is 3000. to about 4000 yuan.

The master of 4S electricity said that it was enough to change the gear lever, so it means that he was wrong?

This should be based on this fault**, generally speaking, there are more problems with the gearbox module.

I don't dare to go to the P file anymore, I've been using it.

Then you should upgrade first as I told you, and if the upgrade does not solve the problem, then you need to replace the module.

If I can help you, please give me a thumbs up Thank you!

Preliminary check that the automatic transmission is working properly. Through the self-diagnosis seat on the left side of the engine compartment, the results show that the normal fault code of the AT system is 444. Switching to the same style A T system ECU and instrument assembly, the fault still exists.

During the re-examination, it was found that when the No. 2 foot of the self-diagnosis seat was hit, the frequency of failure was significantly reduced, so it was suspected that the ECU of the AT-system had a poor tie. Disassemble the ECU wiring socket and check the conduction between the ECU Pin 1 (red and brown) and the car body, and the result is that the resistance value is normal only when key-on is only displayed (the resistance value is. But when the engine is turned on, the resistance immediately becomes tens or even hundreds of ohms.

After careful searching, it was found that several direct tie wires, such as the A T system ECU direct tie wire, the air conditioning system lap wire and the engine ECU lap wire, were mistakenly installed on the fixed iron clamp of the carbon canister oil and gas output hose.

Troubleshoot the AT-system ECU cable separately.
