So my 2007 leon fr has a rusty wing. I'm the second owner and had the car since 10k miles Never been in an accident or even had a car park knock. I checked the corrosion warranty and took it to my local dealer. I was told that the warranty only covers for 10years and mine is over by 5 months! Ouch! The dealer commented on the cars excellent condition and agreed to offer 50% towards the cost. I haven't read too much of this happening to Leon's although it seems common with mk5 golfs.
