It's pretty straight forward to clean the EGR tube. However, it's a bit tedious. You may use some EGR/TB/Carb cleaner and a braided cable with a drill to clean it out.
Sometimes its the valve that has the restriction; other times, you will find the passage in the intake manifold has become blocked.
So, do not buy anything until you clean all the EGR passages from the exhaust manifold to the intake manifold out first.
