Compare Mazda diesel engine fault quotes from specialist garages

Mazda is named after Ahura Mazda, the Iranian-Zoroastrian God of intelligence, wisdom and harmony. Since the company was founded in 1920, it has built a reputation for creating efficient, sporty vehicles that are fun to drive. It's also famous for creating the rotary engine, which uses fewer moving parts than a traditional piston-based engine and features in several Mazda models, including the 1969 Luce R130 coupe.

The Mazda MX-5 Roadster has been listed as the best-selling two-seater car in the Guinness Book of World Records several times. It was also used to make history in 2022, breaking the record for the largest parade of Mazda cars with 707 MX-5s.

Diesel engine repair jobs are often more expensive than petrol, although diesel cars are more reliable and economical over long distances. The main difference between petrol and diesel engines is that the air is compressed before the fuel is injected in diesels, while in petrols, air and fuel are mixed first, then compressed and ignited.

The most common problems experienced by diesel engines include a clogged diesel particulate filter, stuck EGR valve, turbo failure, worn glow plugs, faulty injectors and low compression. Due to the chemicals and processes involved, some jobs, such as DPF cleaning, may require a diesel engine specialist service.

Many of the above faults have similar symptoms, so the best way to find the specific problem with your vehicle is to use diesel engine diagnostics. If you're experiencing issues with your car, we recommend finding a diesel specialist who can give you expert advice.
