    I need to replace the EGR vavle and maybe the cooler.. The problem is that a tutorial I watched is not the same as my year and I don't see any videos of a layout like my 2016 Prius hybrid.

    Directly to the right of the EGR on my car is the inverter which seems to be in the way. Will I need to remove the inverter to replace the EGR vavle?

    Thank you.

    What's the miles? Gen 4 EGR systems have proven VERY butlet-proof. @Raytheeagle did his (did require a inverter shift IIRC).. @jerrymildred did one at the shop he worked at, customer request. To best of my recollection in both cases cleaning proved unnecessary; the systems were still very clean.

    Here's Jerry's post:

    150,000. I took a putty knife and blocked the path of the EGR took her for a test drive and the problem immediately went away. No more shaking on acceleration.
