|  vRS Octavia faults 17545, 17705 Had an engine check light come on in heavy traffic. Dealer checked VAG-COM: 17545 is Bank1 mixture adaption system too rich 17705 is Connection charger-throttle valve pressure drop. Checked valves via VAG-CAM nothing found and resets OK. Drives fine with normal boost. Any ideas what could have caused it? Chris |

I had a chat with an Audi technician when the coils failed on my S3. I'm sure he mentioned something like this happening when you swapped fuels (IE you've run on RON98 for a long time and swap to RON 95 or vice versa) long time ago though, so a bit faded.... | |

| Additional.... A small tip for anyone else having a fault code question. Enter the code into the Briskoda search facility...chances are it will yield results. Failing that, try the same on Google  |

Thanks for the tip. That thread doesn't conclude anything. Strangely enough I AM running 98 on this tank as they don't have any regular 95. Could it be the fuel type? Chris | |

I had these codes, there was a couple of things changed on mine, but a new DV has sorted the problem. I was given the run around by my previous dealer who couldn't sort it out even though there was a technical bulletin issued about this code. This code will keep reoccuring (even though the light won't come on) so I'd get the dealer to look into it. As far as I know its due to the DV sticking when cold, so hence the problem will occur after cold weather. Let me know how you get on. BTW Theres been a number of different threads in relation to this problem, do a search for 17705 and GAFF and you get them.

The dealer confirms there is a TB 56 that refers to this. They inferred that part of it is to do a visual check on the hose to the IC that TaviaRS refers to that is the subject of a hose/clip design change to see if looks like its leaking oil. I will get them to run this test soon. When they VAg-COM'd it I got them to recalibrate the throttle and strangely enough it seems to get more boost for a given thottle opening (I have a Boost gauge) so there doesn't seem to be anything wrong with the DV yet. It happened in heavy traffic after about 20 mins stop/start. Any further comments welcome. Chris | |

The problem was ongoing on my car for 3 years. I thought from the bulletin that the DV is one of the first things to be changed ? See what your dealer thinks of the hosing but if all else fails, don't rule out the DV. BTW What year is the car ?

 , Just to make sure I brought it into the dealer to check for the fault code, still all clear after 6 weeks (and the weather has been cold so it probably would have shown up). Finally sorted

Many people must have suffered from the pipe design causing a pressure drop although I had expected the DV to be the cause as it is running increased boost (Jabba). The techi said the DV seemed OK. I can see the next question is going to be which to change to: Forge, Bailey or Hyperboost? Chris | |

| Mine was not the DV, but the pipe underneath.. I may have *ahem* caught it on the road at some point
