    Hey all,
    Have 2011 Prius at 155,000 and I’m thinking of having the EGR valve, cooler and pipe and the intake manifold (all 4 ports) cleaned.
    Not experiencing any issues but out of preventative maintenance.

    1) How can I confirm the work has been done?
    2) How much should it cost?
    3) Any recommendations on a good shop near Northern Virginia where I’ll get an honest work done at a honest price?

    Thanks!

    Pretty hard to confirm. I think best bet would to find a shop with a good reputation for doing EGR cleaning. Which may be easier said than done.

    2) How much should it cost?

    I've heard $600~900 USD

    3) Any recommendations on a good shop near Northern Virginia where I’ll get an honest work done at a honest price?

    Leave that to other responders, hopefully somebody fits the bill. :)
