With winter approaching here's something that may help someone.
A couple of years ago whilst in the Alps in Winter when I started the TD5 in the morning the fuel pump would buzz loudly for the first couple of miles and then settle back to running normally.
I was advised by Perfectland in Sallanches that what happens is that some cheaper fuels contain a little more water. This tends to accumulate in the fuel filter and can freeze when it's really cold to form a plug. Hence the buzzing fuel pump in the morning trying to force fuel through a restriction. As the fuel warms up after a couple of miles the plug melts but stays in the fuel filter to refreeze later.
Change of filter and all was well.
His answer was to only use top quality fuel which is fair enough but my fix is to make sure I have a new clean filter on for the start of each winter in the alps as it's a lot cheaper and has worked so far even when it's down to minus 30 and the diesel itself starts freezing.
Hope that helps
