Hello Friends !!! Im new here !! I hope someone can help me !! Im looking for the map where is set the min Intake Air Temp limit !! by coldstart the car has no power that means error 17705 !! if i turn off and start again car runs normal !! I know it is set to 5 degree !! if i set it to -5 oder -10 the problem will be solved !! maybe someone has done it in the past and know whrere to find it !! must be a singlevalue im my informations i cant find this map !!! This Problem have many 1.8T chipped but somtimes happens this if the car is stock too !! this is the error code http://wiki.ross-tech.com/wiki/index.php/17705/P1297/004759this happens only on cold days !! maybe someone know what i mean and knows the a solution !! thank you !! KIng Regards !! 0261206794 1037360314 8N0906018J 0004 |

I think the map you need to stop the 17705 code is fvpdkldus in most map its just before kfdluls map for over boost deviation.
I hope it helps, If not let me know and I will look into the file.

hello thank you for answer !!! i have spent a lot of time to try to solve it !! please have a look at the file or tell me what i must change to solve it !! every cold day i get this error 17705 only on cold days !! is the outside temp over 5 or 6 degree that fault will not happen !!!! thank you for your help !! king regards dobermann |

The solution is easy, it is a classic fault on some 1.8T versions! On cold start you will have that issue! You have change the leak diagnosis or by deactivating at all, or you can start leak diagnosis at higher RPM from cold start, So if cold start is at 1300rpm, you can start leak diagnosis at 1400 rpm and the problem solved! very easy  It has nothing to do with boost deviation, it is a leak diagnosis bug |

this happens only on cold days !! maybe someone know what i mean and knows the a solution
Have you considered that the fault code might be genuine and there might be a faulty component which is sensitive to low temperatures? I.e., before you go tweaking map settings to dial out a 'bug', are you certain you don't have any leaks in the charge air system or a faulty solenoid air divert valve or dump valve which could be sensitive to temperature changes? I haven't come across this so-called bug before, but boost leaks and faulty valves on the 1.8T motors are extremely common and they don't always throw DTCs, particularly in the case of 'sticky' solenoid-actuated valves. As we all know, leaks after the MAF sensor will result in an enriched mixture. Don't overlook the obvious. Another other issue that can manifest itself during a cold start (i.e. enrichment regime, e.g. for catalyst heating) is if there is a physical overfuel, for instance if a higher pressure fuel pump has been fitted, but the fuel mass to injector on-time conversion factor has not been re-calibrated to take account of that. 4 barg upgrades to the stock 3 barg fuel pump are popular with 1.8T motors but, from the Bernoulli equation, this will give an approximately 15% overfuel across the board. Just some general issues to think about... Doug |

On these versions you MUST deactivate leak diagnosis because it is software bug... "Tested with other software version and was ok" |

"Tested with other software version and was ok" yes right !! you have to change 3 adresses an the bug is solved !! this problem happens by all 1.8T with 1 MB sw ( AMK and BAM) |

I have faced it only in some versions not all! Not 3bits, just one. Leak diagnosis..... If you don't want to deactivate leak diagnosis you can set it to start from 1500RPM instead of 750 stock |

Carl, this is 1bit value! I usually deactivate boost deviation and leak diagnosis, or increase the deviation to 500hpa so it is not so sensitive! BTW I have reach the point that the best setting for a big turbo is a MAFless setup. No leak problems No dead MAFs No crazy fuel trims cause of bad MAF or leak problems lol |

Carl,
this is 1bit value! So to completely deactivate leak detection is 1 bit (1 out of 8388608). What about the location where the detection threshold (RPM) resides. It sounds like a much better option to raise the limit than to disable it? Thanks! |
