The EGR valve can be a real pain in the a** for driver of diesel cars. After a few miles, they seem to get filled with gunk and this can cause real issues when the valves inside the part start to stick. It often results in error codes from the car, and in a lot of diesels, such as the video producer’s Audi A4, it can bring on a turbo overboost issue which can eventually blow the turbo.
So while a lot of us would simply buy a new one, some of us might even just take our car to a garage, this guy stripped his EGR down, cleaned it completely, and finished with a good polish to make it look better than new. The EGR pipe also had a seeing to, after he found out it was blocked with crap.
This is one of the most satisfying things we’ve ever seen, so make sure you check it out!
