Hi guys and thanks for the welcome .... yeah car reaches normal operating temperature and doesn't boil up sits at 90 degrees and the water in the reservoir isn't hot hot just warm ........ it started when I blew a fuse for the interior light I replaced the fuse went for a small drive about ten miles and could hear the cooling fans running .... the air con is switched off also ..... someone mentioned maybe dpf regeneration bit don't think mine has that function
kind regards
Russ
