Really it is a waste of time taking them out and cleaning them - if you are going to go to that effort the just replace them.
When EGRs fail it is more than them just getting clogged up - the operating mechanism also breaks down and there is nothing you can do about this.
Others experience shows that the EGRs fail soon after their removal, cleaning and being put back in as the operating mechanism is a little slower to break down than the clogging up process. By cleaning them only half the job is done.
If you shop around overseas new EGRs are not all that expensive but you are better blanking and getting a software patch.
