dont need arch liners or wheels off just bumper
You need the wheels and arch liners off to get the bumper off mate!
Crazy talk (you must be a renault tech as they tend to do this for no reason), you only need to turn the wheels and you can take the two nuts out that connect the wings to the bumper. The arch liner is pretty soft and can just be pulled out of the way to get to the nuts. There are a few guides around i willl try find one.
