CT is ok but we've only been down this way for around 9 months so maybe too early for a quality opinion except the traffic is worse than I've ever known and everywhere are roadworks narrowing lanes to widen payments and cycle lanes, apart from one-ways and pedestrianised routes.
On the fogs question, saying the front fogs haven't worked since you tried the rears, random thought is to check the tailgate/hatch wiring looms inside the rubber boots between the body and the hatch. Near the right hand hinge especially. Habitual opening and closing the tailgate causes the wires to fray or break, shorting stuff out. Maybe??????
You've checked both fuse panels, assume?
