DAF XF105 Engine Problem

the big un:

Wheel Nut:
As a rather unhelpful post compared to the others, it might be just taking in air to the fuel system, leaking pipe or summat! or maybe the rest are right and it is only zb Scanias that are 100% reliable…

Nowt wrong with the truck, just change the garage

The firm has had new fuel filters the pumps tested lines blown through,the engine controller ecu changed
but nothings changed the fuel consumption is a very worrying 6mpg on one and between 7-7.5mpg on the others :open_mouth:

It used to be called “Hunting” which meant it was hunting for fuel to create the big bang. I bet it has a leaking or a cracked pipe, but the fitters laptop computer wont find that, you need an old fashioned mechanic with a good ear :stuck_out_tongue:
