Matt what is the actual positioning that you think is flexible? I've not noticed anything obvious like this on mine and I've recently gave it a deep clean, wax etc.
The elongated bit of the wing that meets the windscreen pillar. The corner that meets the windscreen itself is rock solid, but the opposing corner which meets with the rubber surround of the little window by the wing mirror can pushed to flex quite easily, and was flexing when I was rubbing off the excess sealant after applying the C2V3.
I was down to Benfield to pick up the oil filter and sump plug (£15.44 total! Probably £7 at the Skoda garage if the Octavia VRS Petrol uses the same) - the filter is tiny! Smaller than those 150mL cans of pop that you get on a commercial flight when the trolley comes round. While I was there I was looking at their used stock. Unfortunately they didn't have anything MK7 older than 64 plate to know if these used to be more solid at both sides. For the 3 Golfs I tried, they all had the flex that I describe, including a 15 plate Lapiz R. They actually had 2 lapiz Rs in, both on Cadiz - I think my £800 was well spent as I didn't like it. Another brand new Red R on Cadiz in the collection bay looked fine.
Anyway, was having a bit of a chat with the lad at the parts counter as he's getting a GTD shortly, so spoke about that for a bit. He was asking about the car and told me that they'd had 5 Rs over the past 6 months that required a whole new engine because of turbo failure and the resulting shrapnel buggering it. They have 2 new engines on back order right now for the issue. One of them went under a week old, but that was 6 months ago and they've had turbo revisions since (so he said as he tried to reassure me mine wasn't about to pop!).
