I was speaking from personal experience. All fitted correctly with the clips provided maybe that was the problem. No need to jump on the team heko band wagon boys
If your golf is a 2006+ facelift model then you need the non projector style fogs http://www.ebay.co.uk/itm/VW-Golf-MK5-GTI-front-fog-light-lamp-lights-Pair-/171331082915?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Plat_Gen%3AMK+V%7CModel%3AGolf&hash=item27e420daa3
I already answered on the other thread that your fogs won't fit a GTI bumper, but now what you wrote mixes it up again.Are you putting on a genuine OEM bumper, or a replica? Because if it is a replica your existing fogs are the same fitment.
