I have a 2001 td4 and a set of fog light in a box in the back room.
The way I understand it is that the fbh is in the way. There are two options.
1. Replace the front bumper with the v6 bumper, which gives more room.
2. Make a bracket to mount the fbh a few inches further back, to make room for the fogs.
The v6 bumper is not an option for me as my nudge bar won't fit it. I simply have not got around to looking at moving the fbh.
