Update on this, I took the unit out and found I could remove the grommet where the wires disappear into the unit. I also took off what look like little “breather“ pipes. Put the unit on a radiator for a couple of nights and that dried it out. I inspected the lens unit and spotted what looks like a split, so have applied some clear sealant. Put it back on and it seems to be working ok just now, will see how it fares over a longer term.
I've also got a lot of condensation in the front headlight unit so want to see if I can do the same to that, I’ve seen the comments on taking it out involve bumper off (which I don’t fancy), anyone got any other ideas? Could I get inside it in situ to maybe dry it and put some desiccant bags in?
Yes I could do that, it’s just the garage is full of the dry & clean XK, and if I put the XF in that will get wet.
Shame it’s the offside, as the near side arch needs fettling so I could have done both jobs at once. Never mind, not as though I have work to do, like some of you.
