    When did you first clean your EGR valve and why? I’m at 140k but is this something that I should get cleaned/replaced soon? I never heard of an EGR until someone told me about it on Reddit. Thanks everyone.

    EGR clogging issues are associated with Gen3 liftback Prius, years 2010-2015
    Most issues relate to 2010-2011 (perhaps all 2010-2015) model years of the Gen3 liftback,

    I personally have not read any EGR issues on the "c" version of the Prius.

    Link maybe?

    I did the egr circuit on our old 2010 at around 120k miles.

    At 140k miles, I would consider doing the job sooner rather than later;).

    Getting the circuit clean, then doing the cleanse every so often thereafter (I did every 50k miles as that interval) ensures there is one less thing to go wrong with your Prius :).

    The job is not that difficult, just fiddly:cool:.

    Hope that helps(y).

    Prius c EGR is per 2nd gen Prius, very rudimentary, and not problematic?

    Sorry, don't have more info on it. The Repair Manual makes a couple of token mentions of it, that's all.

    It is probably mostly on the 2010-11 models simply because they have been running longer and are getting there first. I cleaned my 2012 at 92k miles, and found it clearly building the same problem, but not nearly as bad as the pictures others with higher miles had posted. So mine still had a long way to go before becoming serious, likely past 150k.

    Since 'v' models have the same engine, they should also face the same issue. But since the 'c' was mostly carried over from the Gen2 with an older smaller engine, and a more rudimentary but non-problematic EGR system, it seems reasonable that it may not have this problem at all. At least I haven't been hearing about any victims of it. Nor any pattern of head gasket failures stemming from clogged EGRs.

    Thank you for the clarification. When I posted my maintenance schedule on reddit, someone said that I didn’t have my EGR on there. I don’t think they knew I had a C. I hope mine doesn’t have any issues down the road but it’s unlikely. Thank you

    Yeah, I think that's what culminated in @Ragingfit doing a 4th gen to 3rd transplant on his v. He ran it with the EGR disconnected for something like 50K miles prior to it imploding.

    Hmm so this person had an HG failure due to the EGR then went to a Gen 4 engine swap which then failed due to EGR being discontented?

    When you can't drive the car anymore cause the EGR is hung up just unplug it.
