LD Auto began its history in 1990 as a small family business in the Leiria region. Its main  activity was the repair of diesel injection components, injection pumps, and injectors.

Currently, LD Auto is one of the brands that comprises the Leiridiesel Group. This denomination was created to meet market needs, maintain leadership in the diesel injection component repair sector, and simultaneously solidify its position in the multi-brand vehicle maintenance and repair sector. In 2019, to provide our professional clients with the opportunity to easily access product information and characteristics with just a click, an online store for professionals was launched.

One of the keys to success for growth in the automotive mobility sector has been the constant search for automotive assistance solutions, always keeping in mind the guarantee of excellent service for the customer. In this sense, the company is involved in multi-brand maintenance of vehicles with combustion, electric, and hybrid engines, and is engaged in the repair and reconstruction of diesel and gasoline injection components, turbos, gearboxes, and particulate filters.

Today, the company prides itself on being a reference in the mobility sector throughout the country, specializing in multi-brand vehicle maintenance and repair, boasting over 30 years of experience and over a 200 employees.
