[quote name='InstructorPiggy' post='55321' date='Dec 18 2009, 10:26 PM']due to cold weather I would think they are staying on for a little longer till min temp is reached and tis just telling you so!
Older diesels would keep the glow plugs on for a good 30seconds when engine has started...wernt direct injection....now direct injection, they barely need the glow plugs...just when gets nippy!
Hope that helps :0
and anyone please correct me if know any different...i know on some models of Ford, a flashin glow light is an error code...but seems to fit with weather my explanantion![/quote]
sounds like a good explanation to me
