Sorry for raising this old topic.
Looks like a decent solution to the sticking throttle body problem. I have the same issue on mine so going to give it a good clean, and if that doesn't work, will probably do this mod, just wondered how you got the measurements for the holes to drill. Was it just guesswork or is one of the hole oversized in order to get the retaining screw in the right place please?
Also, is it possible to get the TB off without getting at it through the wheelarch please?
I don't see why you'd have to take it out through the wheel arch...
I just unclamp the intake, pop off the hoses, remove the connectors and cable, and unbolt it.
