Would you believe, Boxing day and my car would not start and I was 50 miles from home. Eventually had to have breakdown rescue me as they couldn't find the fault. It was later found to be a blocked fuel filter in the tank. The garage said it would need a new pump but on inspection they found it to be blocked with an 'algae' like substance. After a thorough clean problem solved. 2.0L tdci 2013 Titanium now runs like a good 'un. More than likely cheap supermarket fuel. Now using premium diesel every 3rd fill up, and no further problems.
