Hello there, proud owner of a C5 Tourer (59 plate). It has more ups than downs and has been very reliable. Picked it up from its interim level 1 service and MOT. It appears that the rear fog lamp clusters had melted and were duly replaced. I phoned the guy at the services dept and expressed my concerns as to why this could have happened...having NEVER used the fog lights since i have had the vehicle. This coupled with the reverse lights not working did not make any sense. I have searched through these forums to no avail and wondered if it is just one of them things or are my concerns justified. Any help in this would be greatly appreciated. Thank you
