2011 S40 T5 CE light on, threw P0400 code, indicating EGR flow problem. But, does this 2.5l turbo engine even have an EGR? I've read a lot of conflicting info. Mechanic says code is invalid. Can anyone offer any insight? Would be greatly appreciated. (My first Volvo).

tks

 

That's just a generic code which doesn't help at all. You need a shop that has VIDA to read the codes.
