Hi craigboardman, did you get anywhere with VW with this? I have the exact same problem with the same car and I’m waiting for them to get back to me.craigboardman wrote: ↑Sun Aug 30, 2020 5:51 pm Hey, my girlfriends 2010 polo sills are bubbling and after inspection I have found a small hole at the front and back of the sills at the bottom. This looks to be from the factory and would certainly let more water in from the front due to water spray coming up from behind the wheels (back end of sill is infront of wheel so would be less effect). I am going to contact a VW garage as sills should NOT have holes in them. I will try get photos / videos up if there is much response
