First, watch this video in full to get a clear idea on whats going on: - I just did this to my car, its a little fiddly to get the spring back in, but I managed to do the whole lot in about 15 minutes. Completely worth it to be rid of this issue. I jacked the car up on that one side, and used a jack stand just to help. But the video outlines what you actually need to do very clearly and I can confirm our valve system is identical... Here is after about 2 mins... Here is the stretched spring. I actually had too much trouble getting this amount of stretch back in, so I pushed it back about 50% of the way between the pic above and where it is here, so as the video says aim for about 4mm, but personally I would do closer to 6 or 8 just to make sure you solve the problem... Here is the video from last year of the dreaded full blown rattle just for a reminder: And today, excuse the curious kid I can assure you the issue is 100% fixed. there is ZERO noise coming from the valves. Any noise that is there now is coming from upstream, probably wastegate, I couldnt care less, this is DRASTICALLY fixed by my book. Valve operates just as it did before, its instant and you can hear the valve opening and closing with zero difficulty, so I am not really worried about the little valve motor. I actually have my valves disconnected anyway in the past week or so because I prefer the added sound. But I really wanted to fix this issue anyway, and I am really glad I did. The small amount of raspiness you hear in the new video when I rev between modes is coming from the whole exhaust pipe upstream, so that's completely normal, and I confirmed the sound was coming out of both pipes, so that's definitely zero valve rattle.
