Sorry if I've mentioned this before (age is a curse!), but does any other XF owner (2011-ish) have any experience of the interior light(s) above the windscreen and in the back, lighting up randomly when driving along?. In my case, it's mainly the centre light (with the back ones) and occasionally the one to the left of the centre one as well. After a few touches on the lens, it/they go off, but I simply wish they didn't light up in the first place! Any suggestions for a cure gratefully rece
