Happened to a good friend of mine couple of weeks ago. Luckily I knew and had told him of the issue and he had already driven my R so knew what it should feel like. Collected new R, drove home felt hard. Checked tyres, dealer had over inflated to move car around showroom, tyres were over 70psi (should be 36. Car still felt hard, checked and 2 pucks either side. He got first 2 services thrown in after kicking up a storm. Got to check every time, there must be loads of Golfs on the road that still have these in and owners unaware if they've been missed on original PDI, dealers will not check afterwards.
