Hello, owns a Golf 5 from EZ 1/2008. Up to now the rust kept in limits, subject is well known. I changed wheels on Saturday, pressed very carefully into the threshold because I thought there was dirt and then the hole from the threshold was already there, before you saw nothing from outside. Technically, the car is impeccable, 1.4 80 hp gasoline, TÜV up to 1/2025 with 170,000 km. I can not repair myself, can please tell me what I calculi for such a repair. As much as I read about the topic of rust golf 5, wheel boxes, sleepers etc., I would know before I decide to repair it, it makes sense to remove the wheelbase and convince yourself what the rest looks like? Maybe you have some tips on what I should pay attention to. Thank you JD
