Compare Subaru diesel engine fault quotes from specialist garages

Subaru is known for using the innovative boxer engine, named for the horizontal movement of the pistons - almost like a boxer throwing punches. The flat layout of this engine provides better fuel efficiency, and its low centre of gravity makes it more responsive.

In the 2020 Driver Power Survey, Subaru was voted the best manufacturer for safety features for the second year running. And it isn't just cars that Subaru manufactures - it also has an aerospace division that develops and creates parts for planes, including Boeing's 777 and 787 passenger jets.

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.
