I have a 2006 Audi A3 2.0T I keep getting the code p0089 valve for fuel metering N290 implausible signal.What does this mean? What do I have to change in order for that code to go away? Also, when i leave it running for a while it turns off by itself. Does this have to do because of the code that is marking?
My car has 190995 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
To resolve diagnostic trouble code P0089, the mechanic would test the fuel pressure regulator, check for a clogged fuel filter or screen, check for restricted fuel lines, and test fuel pump output. Typically, the problem will be found in those latter areas. With regard to the stalling, given that the code references potential fuel starvation issues, it is plausible that the stalling is related to the fault that has caused P0089 to set. To get this problem resolved expeditiously, please request a check engine light diagnostic and a certified mechanic from YourMechanic will be dispatched to pinpoint the cause of the fault. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair.

To resolve diagnostic trouble code P0089, the mechanic would test the fuel pressure regulator, check for a clogged fuel filter or screen, check for restricted fuel lines, and test fuel pump output. Typically, the problem will be found in those latter areas.
The P0089 code indicates a possible issue with the fuel pressure in your vehicle. The base of the problem is that the fuel pressure sensor is showing a fuel rail pressure that is distinctly different from the desired fuel pressure.
What Does the P0089 Code Mean? Diagnostic trouble code (DTC) P0089 stands for “Fuel Pressure Regulator Performance.” This trouble code sets when the powertrain control module (PCM) has determined that the desired and the actual fuel pressures do not correlate.
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls. If your check engine light is on and your car has been stalling out, you may have a fuel pump failure.
The fault code P0089 indicates that there is an issue with the performance of the fuel pressure regulator 1. This may cause a decrease in fuel efficiency, difficulty starting the engine, or poor engine performance.
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It`s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.
This can be located either on the high-pressure pump or on the common rail itself. The pressure regulation valve serves with the quantity control valve to control the common rail pressure.
For example, failing check valves will start to vibrate and even lose some internal parts when problems begin to arise. Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down.
If the fuel pump relay fails the fuel pump will be left without power. The engine may still crank when the key is turned, however it will not be able to start due to lack of fuel. This symptom can also be caused by a wide variety of other issues, so having the vehicle properly diagnosed is highly recommended.
Three of the most common causes of heavy equipment low fuel pressure are a faulty regulator, a fuel pump malfunction or problems with the fuel lines.
When your vehicle`s Engine Control M (ECM) records a code of P0087, it means the fuel pressure in the system is below specification. Symptoms of a P0087 diagnostic trouble code may include a misfire because of a lean fuel condition, and the vehicle might run rough or lack power on acceleration.
A faulty fuel pressure regulator may result in engine misfires, reduction in power, poor acceleration, and a decrease in fuel efficiency.
This can be located either on the high-pressure pump or on the common rail itself. The pressure regulation valve serves with the quantity control valve to control the common rail pressure.
You will find fuel pressure regulators typically located at the end of the fuel rail on mechanical return systems, or at the fuel tank in mechanical return-less fuel delivery systems.
This can be located either on the high-pressure pump or on the common rail itself. The pressure regulation valve serves with the quantity control valve to control the common rail pressure.
Code P2293 is a code indicating that the fuel pressure is different than commanded to the injectors by the ECM. The problem may cause various problems due to the fuel pressure being too low or high, if the sensor is failing or failed.
Overexposure to extreme temperatures, weather, vibration, and/or corrosive fuel vapors. Over filling the fuel tank will cause fuel to overflow into the charcoal canister and other overflow lines can cause the sensor to fail.

I had a p0405 get code replaced egr valve, map sensor,mad sensor, and PCv valve just to be safe but still getting the code why?
ANSWER : The code P0405 and a rough idle is most likely due to carbon getting into the EGR pintle. This will hold the EGR open. When you are getting the rough idle you should shut off engine and remove EGR valve. Check to see if carbon is holding the pintle open. If it is then you will have to remove the carbon from the pintle. Then try and clean out the EGR passages by scrapping them using a round wire brush. Afterwards, start the engine for a few seconds with valve removed to blow out loose carbon. You should then spray a small amount of carbon cleaner into the passages to dissolve the carbon. Lastly, reinstall the EGR and reset the light and codes.
If you’d like assistance with this, consider YourMechanic, as a certified professional can come to the vehicles locations to perform these checks and properly diagnose your Check Engine Light.
the car is acting like its getting to much fuel. changed the fuel pump, fuel filter, and the fuel pump relay.
ANSWER : There could be a few things contributing to your problem. You are correct that clogged or sticking fuel injectors and possibly the fuel pressure regulator could be faulty. A plugged catalytic converter can also cause the vehicle to bog down. A failing throttle position sensor can cause the symptoms you describe as well. I suggest having a certified technician, like one from YourMechanic.com, do a few tests to determine the exact cause of your starting concern.
Installed new delphi fuel pump and fram fuel filter. still no pressure on fuel rail valve and wont start. 2003 Chevrolet Tahoe
ANSWER : Hi there – I suspect you have weak power getting to the fuel pump. I would first check the voltage coming out of the fuel pump relay. If the contacts in the relay are burned, you will not get reliable current flow to the pump. Check the fuel pump ground as well (voltage drop across the ground, not just continuity). I recommend a fuel system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
Just replaced my fuel pump but its not getting any power tested fuel pump relay and fuel fuse both good tested the wires all good.
ANSWER : You need to look at the theft light on dash to make sure it comes on and goes off when you turn the key to the on position. If light comes on and stays on then your theft system is causing the fuel pump to not be engaged. I recommend you check the theft system and then scan the computer for theft system codes. You may need to reprogram the keys to work or you have an bad sensor for the ignition key in the steering column.
Check Engine Light codes. 2006 Mercedes Benz E55 AMG
ANSWER : Since you are getting many different codes from different areas of the engine, you may need to have the system hooked up to a factory scanner since most of these generic codes do not cross over in my repair software. I would also check with the local dealer to see if any service campaigns are open on the vehicle since there are over 30 possible campaigns that could pertain to this vehicle and some of the problems you are having with the secondary air system. This may be the cause of some of the codes and supercharger disabling. If you’d like to have this checked elsewhere, a qualified pro from YourMechanic can come to your car’s location to go through each Check Engine Light code firsthand and have them resolved.
Cranks and runs rough have to keep foot in gas to keep running. Has new fuel pump and died while driving after pump was changed
ANSWER : Check fuel pressure. There are only three possible explanations: a fault in fuel supply (plugged filter, injectors, etc.); ignition system problems; and air induction including the idle air control valve, throttle position sensor, mass air flow sensor and vacuum leaks including the PCV and EGR systems. If obvious, and easy to check, possibilities do not reveal the fault, the recommended service to request is a rough running diagnostic and the responding certified mechanic will travel right to your location and get this diagnosed and resolved for you. It is also possible that diagnostic trouble codes have set and the mechanic will attempt to retrieve those using an appropriate scan tool. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.
I changed the fuel pump in my car thinking that it was the problem, but I’m still not getting power to my fuel pump.
ANSWER : If there is access to a wiring diagram, you can disconnect the fuel pump harness and install a test light in between the power and ground circuits and turn the key to accessory or try to start the vehicle and if the test lamp lights up, the circuit is not the problem and you may have picked up a faulted new fuel pump. IF you can hear the fuel pump power up and there is no fuel pressure at the fuel rail, the fuel filter may be clogged. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer inspection of the vehicle to run a few tests and offer a more personal diagnosis of your fuel system concerns.
