Hi, personally for the duration of removing your egr valve and cleaning it, I would start with that, see if your air filter needs changing then look at the pipes for leaks as last resort. Hope it helps!

it sound more like a turbo/vac pipe problem, as you car sounds like it went into limp mode, where as a failed egr valve, would not put your car in limp mode, failed egr usually only smoke on hard rev'ing , i would lean more to a failed pipe or a pipe thats blown off
