Hiya
New uk user how do you change a side marker bulb in a v40 2003reg

 

Huh? thought you were asking me..... If you mean the one on the fender I would presume it will pull out like the others (and the clips will probably break and youll have to buy new ones like the others to). The front corner lights should be accessed from under the hood. Not to familiar with the 40s but all auto lighting is pretty much straight forward.
