I have just bought an 08 registered 220 CDi Sport and was surprised that there appears to be only one rear fog light (driver's side). I checked the bulb and it is fine. The same bulb is driven dimly for a running light and then brightly if the rear fog lamps are activated, however, only the driver's side lamp gets driven brightly when the rear fog lamp switch is activated. Can anyone confirm that this is correct? Many thanks.
