Sometimes EGR valves are fed by an external tube coming from the exhaust manifold. These tubes can plug up and throw a “EGR low flow” code. Remove and clean, or replace, the plugged up tube that FEEDS the EGR valve. If this is the same code as before it sounds like either a clogged EGR passage or a stuck EGR valve.
