My S-Max is less economical than it was...

The question
Hi,
My 2007 Ford S-Max 1.8 diesel has just had the timing belt changed and now has a massive increase in fuel consumption. Instead of 570 miles per tank it's only 400. Any ideas?
Cheers
Roger

Hi Roger,
That is a significant change, leading us to suspect something may have been altered during the belt change. The tensioner could be too tight, for example, or the fuel pump timing might be out. Well worth bringing the car back to the garage and asking them to check all of this before it potentially causes problems with the engine.
