Question about 2004 Audi A8

2 Answers

The check engine light comes on all the time now and the Audi service dept constantly tells me it could be a 1000 reason why it continues to come on and each time I take it to the service dept, it cost me $128.00 and up. Please offer any advise you may have.

There really are 1000 reasons the check engine light is coming on. If you keep resetting it and it comes back on, and it is not affecting the engines performance it is more than likely a faulty sensor. But thats just 1 of the many reasons. They want to keep you coming back so unless you tell them to fix it. They are going to be very vague. Get the obdII software and reader is the best thing I can tell you. Then you can read the code that is tripping the CEL. Hope it helps!

DO YOU HAVE AN AUTOZONE NEAR YOU, THEY CAN DIAGNOSE THE PROBLEM AND GIVE U AN ENGINE CODE WITH THE PROBLEM, FREE OF CHARGE OR U CAN DISCONNECT THE NEGATIVE SIDE OF THE BATTERY, BUT THAT WILL ALSO RESET THE RADIO CODE SO MAKE SURE YOU KNOW THE CODE BEFORE YOU DO THAT.

How do I know if my 2005 Audi A6 4.2L Qauttro has a timing belt or timing chain?


Chain. A little trick for finding answers like this: Go to the web site for an auto parts supplier (Rock Auto, Autozone, NAPA, etc.) and look up your car. They will only list parts specific to your year, model and engine/tranny. If neither is listed, it means demand is too low for them to stock it, or it is a dealer only part. Alternatively, call an Audi dealer service dept. and ask for a price on replacing it, or call directly to the parts department. They will tell you which it is and give you a price. Quattros are a solid ride. Miss ours. Happy motoring!

The check engine light has come on at approximately the same time that the display states service required. Any relationship? how do you reset check engine light?


you will have to have the codes read for the check engine and see what has happened to the emissions. You can repost, which I recommend and get some help to fix yourself or at least tell the mechanic what is wrong. The two lights have nothing in common, just a coincident. Let me know.

Service engine soon light came on


The computer or ECM constantly tests operation of all sensors and components. When any of the sensor signals is missing or out of normal range, the ECM sets a fault and illuminates the "Check Engine" or "Service Engine Soon" light also called MIL (Malfunction Indication Light) storing the corresponding Diagnostic Trouble Code (DTC) in the ECM memory.

The same happens if a mechanical component of controlled system fails. For example, mechanical problem inside the transmission also can turn the "check engine" light on. Even not properly closed gas cap will cause the "check engine" light to come on - the ECM constantly checks if the gas tank is sealed properly.

To sum up, when the "Check Engine" or "Service Engine Soon" light comes on and stays on, there is a problem with your vehicle. This could be a problem with the engine, transmission, or some emission-related component or system.

The stored trouble code can be retrieved with the special scan tool by the technician. The code itself does not tell exactly which part to replace, it only gives a direction where to look for - the technician has to perform certain tests specific for each code to find the exact cause of the problem.

Scanning for knowed exactly what fault code you have there.

What does rescu failer mean


As I recall that rescue failure light comes on if one of the air bags has a failure and or been deployed at one time. If you check the engine light on the dash and when you turn the key as if you wanted to start the car but just to the first notch/position. The engine light will probably flash. Count the flashes and that is the fault code. There is a way to reset that, I don't recall; however any Lincoln service dept. mechanic will tell you. You may have to go to the dealer to speak to the service advisor to ask. Don't let them make your car an in-patient!

On my 2002 Audi A4 the Engine Oil Sensor faulty light has come on. Does this need to be replaced Immediately? The car is running normally. Can I change the sensor on my own?


Might want to keep an eye on this one.

AUDI has recalled A4 models d/t excessive "oil sludge buildup" (leading to possible engine failure, timing belt failure, and an overall decrease in daily performance). You will note that AUDI has switched from mineral based oil, to synthetic oil for routine oil changes. The aforementioned will allow the engine oil viscocity to remain constant between service point intervals.

What cause my check engine light to come on?


Hi:
there are hundreds of reasons a check engine light can come on. Many are emission system related, including something so simple as your gas cap being loose. A local autoparts store, such as autozone , will usually check your light for free and tell you an idea as to what caused the light

Check engine light on?


Why my Check Engine/Service Engines Soon light comes on?
The engine computer or PCM/ECM
All modern vehicles have a computer or the ECM (Electronic Control Module) that controls the operation of the vehicle powertrain (the engine and transmission). The main purpose of this is to keep the engine running at top efficiency with the lowest possible emissions. With constantly growing demands for better fuel economy and new strictest emission regulations it's not very easy to achieve. The engine parameters need to be constantly and precisely adjusted according to various conditions such as speed, load, engine temperature, gasoline quality, ambient air temperature, road conditions, etc. That's why today's cars have much more electronics than in early days - there is a large number of various sensors and other electronic devices that help the vehicle computer or ECM to precisely control the engine and transmission operation and monitor emissions.
The vehicle computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. To properly diagnose what is wrong, you need to take your car to a mechanic or a dealer. The technician at the dealership or a garage will then hook up the scanner to the car computer and retrieve the stored trouble code(s). Then he (she) will look it up in the service manual provided by a car manufacturer. The service manual contains the list of possible codes (about few hundreds) and describes what each code means and what needs to be tested. The code itself doesn't tell exactly what component is defective - it only indicates where to look, what engine parameter is out of normal range. The technician will have to perform further testing to pinpoint a defective part.
