Further, the Audizine thread is about 100 posts long, has run for 2 weeks, and only just now did people start talking about the facts about that car. Also, Jimmy, why doesn't the B8 get carbon buildup the way the other 4. Not my best work with paint but there are very crappy pictures of cylinder heads from what I saw to better illustrate what I am talking about. Blockages or leaks can be determined for each cylinder bank. This is a common problem on cars like my e39 M5, and it seems several higher-mileage Audis from this decade. The currently selected is for the Audi makes.
Here's the direct excerpt from the 3. Posted on Sep 12, 2013 Did you check the Vacuum lines to the Secondary air Valve Controls. Those up and down ports are the ones that clog up with buildup. The system pulls a vacuum on the fuel system and holds it for a period of time. It took my about 4 hours but I was taking my time and learning as I went just based off what I read from these forums.
I replaced the fuse and reset the the computer. The values are compared with the value saved in phase 0. Both codes are generic in nature and don't tell you anything specific about the problem so the whole system has to be troubleshooted. If it exceeds the set limit value ex. So my stft are now bouncing between 21-26 so I guess my misfire is because it's just to high now to be properly burned or something on the lines? Btw I don't listen to BeyoncÃ© , in the video it just had to come on the radio at the same time of recording. In this system, the signal from G609 is evaluated in the engine control module. Looks like they just cleaned it, checked that the pressure sensor showed there was enough flow through the passage, and passed the secondary air test, then handed it over.

I can only guess that they are using a better crankcase breather setup but that would be a odd change since the 3. Mine was disconnected at a vacuum switch, top of engine drivers side. Aug 14, 2013 A used transmission is always a gamble. The P0491 refers specifically to bank 1. A faulty secondary air pump does not shut off or faulty secondary air injection sensor -1- G609 can be detected.
I have a dead battery now. Just wondering if anyone else had any other ideas at all? Then they drilled holes into each exhaust port for the pump to blow in hot air for the secondary air injection. Car has thrown a bank 1 too rich code at me. It didn't seem like they replaced any part or looked for any leak, though, which is weird. Also the loud roaring noise from the engine bay during cold start was still occurring.
The first is to inspect the system checking for a proper seal. This allows evaluation of the secondary air injection sensor -1 G609 value. If a fault repeats itself, the engine electronics warning lamp will be activated. I find it strange that they didn't mention testing the combination valves or anywhere else in the system for leakage, which might have caused the problem in the first place. Carbon buildup in the air injection ports in the heads, which eventually prevented any secondary air flow and tripped the flow sensor.
After you instruct it to perform the scan, it speaks with your car's computers to find out exactly what's prompting the light to turn on. The B8 S4 now has 110K miles on her. Also, Jimmy, why doesn't the B8 get carbon buildup the way the other 4. They are not sure how to fix it. Audi just replaced steering column module and now this problem. Some of the diesel turbo guys would pull their 4 cylinder manifold off and light it in fire to burn off the carbon buildup. After changing the transmission and clearing all the old trouble codes, what new trouble codes do you have? They drilled out like a 5.
Enter the 5 character trouble codes in the search box and submit the search. The codes are for the secondary air injection systems and the 491 and 492 are for banks 1 and 2. Also the spelling errors are getting odder and funnier as I catch on. We are not responsible for any actions you take on your vehicle. If I had to guess I would say I'll have to get a relay tomorrow and mabe do the pump rebuild.

The only people i know are rtech but that's a 4 hour round trip for me. Trace the vacuum hoses that come from this air pump and you will probably find one has become disconnected. Hopefully they made a big enough change to not have an issue. The car seems to hate a cold engine on start up and idles about 1100-1200rpm for about 30 seconds and then goes back to the normal idle at about 700rpm. Unless you drove the car yourself, that the used transmission came out of and determined that it performed as it should, you will never really know what your getting. The injected air quantity is determined from the pressure level.
Replacing the oxygen O2 sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If no fault occurs during phase 1, the diagnostic process is continued. I would have expected them to at least change a combi valve or something. If you look at the engine pictures I see two hoses going over the intake pipes to probably a valve that is behind the cover. Her idle then fluctuates about 100rpm constantly. There are a few things to inspect when this code comes up.
