@Steve Q thanks for replying mate. Yes I’m beginning to think they mustn’t have been specced when new. Apparently it’s an easy retrofit so been thinking about helping him with it.
In the meantime contemplating a remap for the 3.0 Audi Q5! It’s got poke but more is always better especially if economy is same or a little improved!
Welcome to the forums
Nice friendly atmosphere here with plenty of Audi owners to help where they can.
Please be sure to give the forum rules a quick view
