In internal combustion engines, Exhaust Gas Recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again.


Understanding how it works and making sure that yours is in good condition is therefore essential if you are interested in keeping your truck running efficiently. As a Saab owner, it’s important that you keep the EGR valve in good condition.

Since it has a direct impact on how the engine works, any problem with the EGR will manifest either as increased fuel consumption or reduced performance, and you may see a Check Engine light followed by a readable code in your Saab’s OBD-II or newer computer. Learning when to have it maintained or replaced is therefore important.

In modern diesel engines, the EGR gas is cooled with a heat exchanger to allow the introduction of a greater mass of recirculated gas. EGR Failure is another common problem associated with Saab 1.9 ,  2.2 TiD and TTiD engines, the EGR system is designed to recirculate some of the exaust  gasses  back into the engine, the flow of exaust gassesis controlled by an EGR valve. The excessive  smoke generated by a stuck EGR valve will also rapidly clog the DPF, this highlights how an EGR can reduce the life of the DPF system.

For over 10 years, Goran Aničić has been passionately focused on Saab automobiles and everything related to them. His initial encounter with Saab cars took place back in 2003 when the first Saab 9-3 and sedan version were introduced. At that moment, he was captivated by the car's Scandinavian design logic and top-notch engineering, and everything that followed stemmed from that first encounter. Later on, through his work at the editorial team of the Serbian automotive magazines "Autostart" and later "AutoBild," he had the opportunity to engage more closely with Saab vehicles. In 2008, he tested the latest Saab cars of that time, such as the Saab 9-3 TTiD Aero and Saab 9-3 Turbo X. In 2010, as the sole blogger from the region, he participated in the Saab 9-5ng presentation in Trollhättan, Sweden. Alongside journalists from around the world, he got a firsthand experience of the pinnacle of technological offerings from Saab at that time. Currently, Goran owns two Saabs: a 2008 Saab 9-3 Vector Sportcombi with a manual transmission, and a Saab 9-3 Aero Griffin Sport Sedan from the last generation, which rolled off the production line in Trollhättan in December 2011.

  • Really disappointed that in the video no mention of testing the valve was working and that the throttle body channels needed cleaning out. Only a third of the job shown. The only reason most people would undertake this job is an engine management light caused by carbon build up, therefore you need to be showing all areas to be cleaned.
