    Default <<<<< VAG GROUP HOT START REPAIR AT ONE PLACE >>>>>

    Hallo to all. I See a lot of requests for Hot Start repair in VAG Group (Audi VW Seat Skoda) vehicles.

    It is common know that VAG group 1.9TDI PD engines have typical error. They are starting good in could state, but when the engine temperature is over 80?C the engine is starting very poor. It need some time to start.

    The problem is in Coolant temperature dependent injection starting maps. The engine is not injecting any fuel when the coolant temp is high and RPM-s are not high enough.

    Second problem is faulty camshaft sensor. The symptoms are the same just when you put modified software in the ECU there is no change, and the car is still staring poor. But this is detectable via diagnosis.

    So I think is the best to put all those problems in one place

    When you girls are posting your dumps, please give some typical amount of information too.

    Fox example:

    VW Touran 2004 1.9TDI BXE 105PS EDC16U1

    I will try to help, ones at day, and I believe that also the other DK members will love to help with solving your files.

    BR

    Hi, I have a question about hot start. I use a map of VW touran 2005, BKC, 77kW, 1.9 TDI, 0 281 011 945.

    The first two pictures are orig ... 3rd and 4th are repaired with carsoftware. I understand the first map ... it look like the same as on edc15 (hot start) and know how to repair it (DK members teach me ) because I don't like carsoftware solution so much torque at low rpm - bad for DMF (DK member mislav88 teach me) ... so I repair it my way like in picture 5 ... but what is the map which is also repaired by carsoftware (picture 4) ?

    regards

    Picture 1: Basic starting torque

    Picture 2: Starting torque after clamp 50

    mislav88 teach you good

    Its not good to raise the torque all the way from the 0 RPM, but you can always change the Axis value

    Those generic software are sometimes stupid

    But anyway it is not good for the engine if you are giving so much fuel increase.
