Compare SEAT diesel engine fault quotes from specialist garages

SEAT was founded in 1950, back when there were only three vehicles for every 1000 people in Spain. A partnership with Fiat brought the company up to speed with the latest car manufacturing techniques, lasting until 1982 when it was sold to the Volkswagen Group.

SEAT has recently won numerous awards; the SEAT Leon was named Best Family Car at the WhatCar? Car of the Year Awards in 2022, and the Terraco won Best Large SUV the year before. SEAT also has approval from the Vatican - in 1982, it created the Popemobile, which Pope John Paul II used on his visit to Spain.

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.
