I was wondering that too. I was assuming either 2 things 1 is that since his is a 05 vitz its older and maybe utilizes a egr system.

or 2 the mechanic who is working on his car is a idiot and just made up some code. Most mechanics know that when a egr code pops up you simply test the egr with a vacuum pump if egr tests good then its a solinoid if its electronic operated if not then the egr pintle is stuck or the pipe is severely crudded up restricting flow. Either way it can usually be fixed by cleaning the egr system.
