Top 10 2005 Audi A4 Questions & Answers

First thing is to go to Auto Zone or Advance Auto Parts and ask them to scan the computer for fault codes (your check engine light is on, so you absolutely have at least one code in there). They'll do it for free, whereas a dealer will get you for an hour's labor. Do that and then post the code(s) you get up here as a reply to this question, and we'll take it from there. Also, when you reply, please list your engine, transmission, and whether the car is a quattro or not.

AUDI A4- 2005. There is a technical service bulletin for this exact problem. take it to the dealer when this issue has happened while driving. During a daytime drive when cold see if you cant get the light to fail while circling your dealer. As soon as you pull into the service drive do not turn the car off do not flip the switch. I am an Audi Technician for a dealer in Birmingham alabama. Personally this is not my favorite repair to perform; What audi states is that if the bulb flickers the bulb should be replaced; if one side fails the bulb should be swapped left to right if the fault continues with the bulb the bulb is at fault; if the bulb is swapped and the bulb fails again on the same side it is the module. NOW: I currently am working on a 05 A4 that both bulbs both modules have been replaced and Audi has no clue what to advise on a repair. THIS IS AN ISSUE if it has happened to you ask if there is a TSB for this issue or try to find it for yourself.

SELL SELL SELL!!! I have owned various audi's over my lifetime and have always loved the quality and drive that they offer but when i bought my first auto which was multitronic i had nothing but big problems! costly problems which ended in a replacement gearbox and surfing the internet has brought to my attention that i aint the only one!

You could have a bad air flow sensor. Do you also have a lack of power??

the park sensors send out a beam and the return signal intensity tells it the distance.if there is dirt or water in the sensor or it is shorted,it will think you are very close to an object and beep like that.there is more than one,disconnect them one at a time,or take them out and measure the comparative resistance.the one that is no good will read different

At the bottom of the automatic gearbox (tiptronic) you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up. Tightening torque is 24 Nm.


Automatic Transmission Fluid (ATF) checking:
1. Requirements for check:
1.1. Vehicle standing on level surface.
1.2. Transmission must not be in fail-safe mode.
1.3. Shift lever in "P" position, parking brake applied.
1.4. Engine idling.
1.5. Air Conditioner and heater OFF.
1.6. ATF temperature must not exceed 104 Fahrenheit degree (40 Celsius degree) at start of test.
1.7. Only ATF with designation ESSO LT 71 141 may be used. Do not use any lubricant additives.
1.8. Automatic Transmission Fluid ATF - part number: G 052 162 A2 (1 liter wrapping)
1.9. An ATF level check when transmission oil temperature is too low results in overfilling, when too high results in underfilling.
2. CAUTION: Too much or too little ATF will affect the operation of the transmission. The ATF level must be checked at regular intervals.
3. The oil level is correct if a slight amount of oil runs out when ATF temperature is between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg) (caused by increase of oil level when heated). For warmer climates, 122 F deg (50 C deg).
4. Hang filled ATF reservoir VAG 1924 as high as possible.
5. Shift lever in "P" position, engine running at idle.
6. Place oil drip pan under transmission oil pan.
7. Remove ATF filler plug (at the bottom of the automatic gearbox you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up.
8. With ATF temperature between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg), for warmer climates, 122 F deg (50 C deg), a slight amount of oil will flow from filler hole when ATF level is correct.
9. If necessary drain or top off ATF to attain correct oil level. Top ATF with filler hook from VAG 1924 ATF reservoir. Insert VAG 1924 (tool) ATF reservoir filler hook into filler hole and top off until a slight amount of oil flows from filler hole.
NOTE: Fit filler hook into one of the oil deflector cap slots placed on the filler opening.
CAUTION: Do not press filler hook upward or oil deflector cap can be pushed off.
10. Reinstall ATF filler plug. Tightening torque is 24 Nm.

Not having more specific info as to the behavior of your vehicle it's hard to say. what the problem might be. Computer codes are only a place to startt.
The P0722 is for Output Speed Sensor 2 Circuit No Signal. This means that the transmission control module is not receiving a signal from the Output Speed Sensor.
I am assuming (based on this information) that your vehicle is front wheel drive and has an automatic transmission. If you have a different powertrain (i.e. quattro all wheel drive or a manual transmission), write back and let me know.
This P0722 is a common fault on front wheel drive automatic transmissions (called a CVT). The bad thing is that the output speed sensors are part of the transmission control module and the only way to repair that is to replace the transmission control module. The module is located inside the transmission. Expect to pay $1000 to $1500 for the module and another $700 to $900 for labor.
There is a possibility it could be the Neutral safety switch. They an get dirty and cause problems so spend a cople of dolars checking this before laying out the bigger bucks.
Testing Neutral Safety Switch

Required Tools:
Test Light/Voltage-meter
Wiring schematic
Neutral safety switch location (component location)

Test Procedure
Locate the neutral safety switch
Disconnect the wiring connector at the switch
Using a test light or volt-meter test for power at the wiring harness with the key in the "engine crank" or the gear shifter in the "reverse" position. (do not start the engine)
If power exists reconnect the neutral safety switch and probe outgoing wires at the connector.
If no outgoing power is present the switch has failed and needs to be replaced.
Tip : If the engine will not crank over with the car in "park" push down the brake pedal and try cranking the engine over with the car in "neutral". What you are doing is bypassing the "park" position in the switch and now are using the little used neutral circuit. If in neutral the engine starts the switch is probably bad.
Tip: Sometimes a neutral safety switch can become misadjusted. This switch adjustment can change due to normal wear of mechanism that controls switch slider.
Other complications can occur if there is a loose connection somewhere in the system. While this condition is not a shorted circuit problem, it is a condition that simply breaks the flow of electricity intermittently. To troubleshoot this problem consult a car repair manual to locate the wiring schematic for your car. Repair the broken or shorted connection as needed and recheck system. Electrical problems are less complicated when the proper information is available.

You will be able to open the hood if you pull off your splash guard and use a long long flat head screwdriver or something like that. You'll see the hood latch in front of the radiator with the cable attached to it at the top near the hood, put it on the drivers side edge of the bottom of the latch and pry to the passenger side, the lever moves from the drivers side to the passengers side, the cable basically pulls the top of it to achieve this. so your doing the same thing on the bottom with the screwdriver.


Release the latch from underneath by the lever that you have to pry towards the passenger side. Then open the hood, and replace the safety release mechanism broken cable.

Please do rate my response. Thanks!
