The fuel pressure regulator regulates how much fuel is delivered to the fuel injectors. I am so glad that I got out of being a tech when I did because Audi is extending the warranty on so many things and the techs are getting screwed because of it. This code will remain until the problem is resolved. Depending on system design, there are a few ways to modulate fuel rail pressure. It is probably not related but have you ever replaced your fuel filter? Some European vehicles have been prone to failures in this area, typically caused by infrequent or improper oil changes wrong oil blend or viscosity. Here are some of the most common.
Start watching the rail fuel pressure - it should stay steady for at least three to four minutes. Logged I haven't heard of any other 2009s having this issue. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. I've received an extended warranty notice on injectors for my car, I wonder if one is actually faulty. Someone mentioned that it was typically around 2K rpm range at the low end of the fuel pressure range.
Requesting x, but measuring x+y. You should also check that the spark plug gap is set properly. Specific diagnostic steps and verification data depend entirely on year, make, and model, which information can be found in a factory repair manual. The extended warranty notice is interesting. Car mods can be found here: Any ideas on where else I should be looking or am I missing something from the above data? No other codes like P0087? If the engine runs, you may experience poor fuel economy, poor performance, lack of power, or rough idle. While logging a variety of driving conditions I'm seeing a Fuel Rail Pressure range of 536 to 2416 psi 37 to 166 bar. Lacking proper power or ground, diagnose and repair as needed.
Spark plugs typically need to be replaced every season or 25 hours of use. Depending on vehicle type and failure mode, you may experience a number of undesirable conditions and drivability problems. Scan tools allow us to see things such as sensor data, fuel pressure, voltage, ohms and other important information. Spark plugs typically need to be replaced every season or 25 hours of use. A high-pressure fuel pressure gauge would be helpful, but quite possibly unavailable outside of a shop environment.
Logged Thanks for that, i'll try those tests. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. No problems though on white lightning. So you should chech it on our car models. Once the fuel pump fails the vehicle may stop running while driving or fail to start and run. If not then it would be great for maintenance and to rule that out just in case.
Yea the warranty is up to 120k. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. Fuel pressure regulation is different than in low-pressure fuel injection systems, controlled electronically instead of mechanically. Logged Yeah that code with a B7 meant the cam follower was done. This will allow for fuel pressure readings to be taken at the fuel rail. Now don't ask yourself; What should you do with P0089 code? Ask to see the follower, if the black coating is rubbed at all and they won't replace it, complain a bit and wave a big stick, they might cave.
You may not be able to start your vehicle at all, or it may start and run a few minutes and stall. The usual electrical short- and open-circuit problems apply. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off. Ross-Tech is not affiliated with the Volkswagen Group in any way. I have a smog check coming up soon and do not have a clue where to begin to fix it.
The other symptoms such as poor vehicle running, misfire, lean, and rich conditions can cause the vehicle to become unsafe to drive. What are the symptoms of code P0089? The solution is here : Audi Quattro P0089 Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Usually it is on the right side behind the rear door under the car. The other tool required is a professional level scan tool. Take it into a dealer.

If your spark plugs look good, problems with your ignition system can also preventing a spark. Supply pump failure causes a similar situation, but do not condemn the supply pump until you have tested it, as some failure modes cut off the supply pump when there are problems detected in the high-pressure system.
