carista app and dongle for it total of £50 cost, can change throttle response from pants I dont do what you tell me to and work on gradual response to normal direct response.. improves car drivability (not sure why its not this way from factory). Also add chirps to lock and unlock (which should be option anyway) as I have lost count the amount of times I have sat on the key and opened cars or boots lol. Fob to close boot and sunroof, indicators do 5 flashes instead of 3 on light touch for lane changing (another thing that should be std as i think 3 is pointless) and a few other minor items.. But be warned there are a few options in app you dont want to do.. If any of you with tiguans are passing near canterbury let me know and I will meet up with you and do it for you. There are other things like getting video to play on std head unit from mobile via mirror link, or from usb on pro media. handy for when your stuck in car waiting for more that 30 mins.
