Do all diesel engines have DPF issues?
Is there a diesel car yet that can cope with town driving/short journeys without clogging the diesel particulate filter (DPF) and exhaust gas recirculation (EGR) components?

Sadly not.
The DPF is the reason why the latest Euro6 engines are so much cleaner. The filter needs to perform an active or passive regeneration cycle, if it can't do this then it'll fail to burn off the harmful soot it collects and will clog up. Likewise with the EGR, if the engine doesn't reach its optimum operating temperature on a regular basis then it too will fail.
Unless you plan to drive a minimum of 15 miles per journey, I would avoid diesel. Not only will it save you costly breakdowns, but you'll also spend less on fuel - as diesel engines are not very efficient when used for town/short journeys.
