The prestige of owning a luxury car is something fabulous. And if the car bears an esteem logo of AUDI, it is something awesome. As you read the word Audi, the next thing came to your mind was LUXURY. Wasn’t it? Yeah! You are right. Audi Ag is a German Automobile Manufacturer company that designs, engineers, produces, markets and distribute luxury vehicles.
But wait for a while! And think, what happens when such a prestigious company launches a vehicle in the market and the vehicle goes through really stupid transmission problems. In our blog today, we will discuss the transmission problems of 2002 Audi A4 and how to deal with them. At First, go through the basic information that you must know.
What is the Transmission System of a Car?
The mechanism that transmits the power to the driving wheels developed by the engine is called the transmission system or a power-train. “Basically,” transmission system comprises a clutch, gear box, propeller shafts, rear axle and the wheels. The transmission system of any car is classified into categories:
- Automatic Transmission
- Manual Transmission
- Constant variable transmission
Imagine what would happen if there is no blood in our body? Can we survive? The simple answer is No, Not at all. Transmission fluid for a car acts like as blood acts for our body. It is red in color and smells sweet if everything is working correctly. The Fluid lubricates, cleans and works as a conditioner for the seals. Without this fluid, the engine will stop its working. The level fluid should remain at its appropriate level.
Now, as you grabbed the basic knowledge about transmission of a car let’s share the transmission problems of 2002 Audi A4. The list comprises common problems of:-
Problem Associated with the Gear Box
What do you expect from an Audi ride? Smooth running, No jerking and grinding noises. But this story of 2002 Audi A4 is something else. While driving the car, the gearbox starts to jerk, rattle or shake at the time of changing the gears. Manual transmission cars emit sounds that are louder and rough. Jerking or rattling noise of the gear box can be controlled By Changing the Gearbox Oil of the Car. For a smooth Ride, the gear box oil is suggested to change after every 40,000 miles. Also, if the car is refusing to go into the gear, you can execute the following steps:
- Check the level of the fluid
- Check the clutch linkages properly
- Adjustment of shift cables can be helpful in resolving this problem
1. Illumination of the Lights
Gear shifting Lights: This is another problem with 2002 Audi A4 which you have to deal with; at several times while driving the car at a normal speed of 30 mph, all the gear shift indicator lights on the instrument panel get an illumination spontaneously. After this, within a very short period, the vehicle fails to accelerate. Another problem after the blinking of lights (park, drive, Reverse, Neutral) is to shift the car into reverse. When this happens, the car cannot take a reverse. Or if unluckily you are on an incline, the car slides backward on an incline, stepping on the break will also not work. This is a clear indication that the transmission system is defective and needs a replacement.
Check Engine Light: This is not just a simple light; it is a warning. It indicates that your car needs an urgent and serious repair. You must take your car for a service. The light either stays on or blinks. The serious reasons for this illumination are:
- The Permanent fault of the emission control system.
- Engine misfires and catalytic converter overheats to glow red. In extreme cases, the underside of the vehicle can catch fire.
But sometimes for no reason, if this light gets illuminated, you can go through these troubleshooting steps to handle this problem.
- Tighten the gas cap.
- Examine the spark plugs; If necessary replace the spark plugs
- If necessary replace the spark plug wires.
- Check the mass flow sensor. Failure of mass flow sensor also causes this illumination.
2. Delayed Engagement
It is also called the morning sickness of a car. And Audi 2002 A4 is not untouched from this problem. It is one of the most common problems in automatic transmission cars. It is a kind of slip in the automatic transmission.
The symptom of this problem is the delay from the moment you put your car in gear, to the moment when you realize the engage of transmission. The bands which are responsible for the vehicle to move are did not come in an action instantly. In traffic, this kind of problem can make you unsafe. This problem can be fixed by the proper maintenance/replacement of the factors (clutches or bands, Level of Fluid, valves stuck to the valve body, Accumulators) which make the process complete. A burnt smelled and dark colored fluid will give you a prima facie report of all these factors.
If the problem is not fixed by replacing the spare parts which are responsible for Delayed Engagement, the dealership suggests you go through the replacement of the transmission system.
3. Hesitation While Accelerating
This is such a Damn! After shifting the gear from 3rd to 4th and stepping the accelerator; the car hesitates to speed up. This is such an embarrassing moment that you want to speed up your car, and the vehicle is hesitating. This is another problem of Audi 2002 A4 problem. Either you drive at high speeds or not; you must resolve this problem because some factors are responsible for this hesitation. These factors include:
-Improper working/failure of Mass Flow Sensor: The basic function of this sensor is to calculate the amount of air and temperature which is entering in the engine. On this basis, a right amount of fuel is drawn from the fuel injectors. It is quite obvious that failure or bad working of this sensor will affect the acceleration. To improve this failure, check for:
- The proper wiring of the sensor.
- The condition of wires establishing the connection b/w sensor and the computer is adequate.
- If the Mass Flow Sensor (MAF sensor) is failed; Replace it
- Maintenance of the Fuel Injectors: The dirt in the fuel injectors also hinders the supply of fuel to the cylinders. Timely proper cleaning of the fuel injectors and maintenance fuel pump should be done to avoid hesitation problems.
- Throttle Position Sensor: To speed up the car, appropriate amount of fuel/air mixture should enter into the engine. The computer decides this adequate amount of fuel/air mixture going into the engine after the report of Throttle position sensor.
This sensor notifies the pressure applied on the throttle and up to what extent, the throttle is opened. So, proper working of this sensor is a must. Examination of connection of wires, replacement of damaged sensor and a properly cleaned throttle pipe won’t let your car hesitate in speeding up.
Today, on a very serious note I would mention that most of the transmission problems are due to the delayed servicing of the transmission system. And it becomes too late. This is the thing which you can control. So don’t neglect service of your vehicle and be sensitive to all the abnormal sounds of your transmission.
