Egr valves are a shit design. They fook up on most vehicles.
I put a rear wheel bearing in the wifes last month. It went again 2 weeks ago so i went back to euro car parts and got another one under parts warranty. We went to the lakes monday gone and the fooker went again
I had to take it to a garage to get repaired which i hate doing. The garage has put 1 brake drum on and 1 wheel bearing.
I wish she would get rid of it and get a new car lol
