I have had my car diagnoised and the following fault come up
control unit : glow plug
glow plug 2
glow plug 3
i spoke to my garage asking him to get these change so i will get better miles.
he goes this is nothing to do with the miles you get. Where the people that did do the diagnostic said you need to get these parts changed for better fuel.
i am currently putting in £65.00 and returning 320 miles.
its an automatic
i drive urban and town
The computer says when i fill up 480 miles to go
by the time the diesel has finished i only get 320 miles
anyone suggest what can be the problem or would changing the control unit make a difference
