it is possible as i had it coded on my 2003 3.0i. i used an indy in surrey to do mine - probably a bit far to travel.
if you get it coded i would recommend the gaptech RCH+ module (search the forum) as without this you'll have to keep your finger on the button until the hood has fully travelled and stay within range,which slightly defeats the object. with the RCH+ once it starts you can walk away and leave it to sort its self out. standing there waiting for it to finish on the standard set up kinda ruins the look!
