Advice for buyers
What should I look for in a used Mazda 3 hatchback?
There isn’t much to worry about. Diesel Mazda 3s have particulate filters, so make sure you steer clear of any warning lights that arouse concern as these can lead to costly repairs. In 1.6-litre versions, the particulate filter is cleaned with an additive called Eolys, and when this runs out it needs topping up, so make sure this has been done on time – usually around the 75,000-mile mark.
