Delays with the Ford Focus 2.0-litre TDCi mean that any existing orders will not be met until July at the earliest, and new customers will have to wait until October. A blue oval spokesman said: "We've increased production of the 1.6 and 1.8-litre TDCi models, so buyers can switch over if they want." The smaller-capacity units don't require the filter, so aren't affected by the shortage.
Other manufacturers are also facing backlogs. A Vauxhall spokesman told Auto Express: "It has affected delivery times for the Vectra 1.9-litre CDTI Estate, but only by a few months."
In addition, there are problems at PSA - the parent firm of Peugeot and Citroen - although a spokesman said he was unable to identify delays to specific cars. The French firm recently fitted its one-millionth particulate filter. Its patented design is used on nine models, including the Citroen C4 and Peugeot 206.
