    I have a 2012 (62) plate A5 TFSI sportback, has anyone retro fitted the hillstart function and is willing to share the procedure/ installation details preferably with photos. I have an audi spevialust locally willing to install if i can find the installation details for it. I see on A3 forum people have done it so perhaps its the same procedure for A5? Advise and comments appreciated. Thanks

    1st thing you must check is if the abs controller supports the function, as it may not.

    If the installer is asking you to get the install data, use a proper retrofitter imho, no offence as this could go wrong if not careful.

    Thank you, NHN. I will endeavour to find out if it supports the function ( any pointers how to find out if mine does?). I dont believe there is a retrofit installer in my area who has done this before so i looked for a audi specialist with top reputation in the area.

    relatively easy to do if you have a compatible abs controller supports it as the wiring is pretty simple - i done it on my B8.5 A4 and spent most of the time removing trim pieces and running wires to the controller.

    An update to the hillstart.
    I day had Audi enter the hillstart assist codes which worked perfectly. No wiring, no switches ... just codes. Of course this cannot be done on all models as i booked it in initially due to the question from NHN regarding the ABS.
    This coding has also fixed the other issue i was having: when pulling away from lights or junctions, the car would jerk forwards unexpectedly. I have read many people having the same issue. Well the coding for hillstart assist has also sorted this problem. My car now pulls away like a car should. So happy today, finally have my A5 the way it should be and it now holds solid on an incline without foot on the brake!

    You should fit the button for completeness like I did :)
