I suppose the other thing is i still have 3 years warranty, so i would have to be careful, i have been told they cannot detect remaps, i suppose it is "out of sight out of mind", any other things they could not detect, that i could start with as a remap seems to be something to do after a couple of other tweeks, how about a k&n panel filter do these make any difference and i suppose i could change this before my services, if so can you get them for mk2, cheers
