I took my 2007 Focus 1.6 diesel in to a local garage for a 75000 mile service this week. After picking it up, its noticeable that it takes significantly longer to start - used to catch as soon as you turned the key, now it takes maybe 1-2 seconds of turning over before it catches. Not enough to be a problem, but I'm worried in case it degrades over time / suffers more in winter.
I spoke to the garage who did the service and they said that they didn't change the fuel filter because its a long life filter on these cars, and that maybe that is what is causing the problem. Doesn't make sense to me because they haven't changed the filter, and the problem wasn't there before the service. Any ideas what could have happened? Its not really bad enough to consider taking the car back for them to look at again, but equally its a slight worry ...
Thanks
