Just fitted mud flaps to my car. Very hard to remove the wheels due to corrosion on the hub and alloy wheel. Be careful if you need to change a flat tyre. A lady will not be able to remove the wheel, unless she is on Gorilla juice !! I had to hit the wheels with a hide faced hammer and lever them off with wooden hammer handles I have written to VW with a request to a recall to fix this issue. Remove the corrosion and lightly grease the hub flange, should be OK then. No doubt this situation occurs after the cars have stood out in the weather during export etc ? Anyway VW now know about it Happy motoring
