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.
