    EGR Cleaning?

    I contacted my (so far, trustworthy) Toyota main agent and asked the Workshop Controller for a quote on cleaning the EGR system. He replied with £400+ for cleaning the EGR valve and intake manifold. I asked him if he they also cleaned the EGR cooler. His reply was: (Copy & paste) "No we do not remove the cooler as it rarely has issues with blocking, although we do as part of this procedure remove the spark plugs and blow back thorough the cooler , which then blows any carbon deposits back through the cylinders and out of the spark plug holes." Your comments would be appreciated!

    EGR Cleaning?

    Again, a fascinating selection of views, thought and knowledge. For reference, my EGR pipe was at 80k miles and the engine is not using any oil at all: TonyHSD - you could start offering an EGR cleaning service to TOC members! The Workshop Controller at a Toyota main agent confirmed the Gen2 was 'over engineered' and that Toyota made little profit from making it. The Gen 3 was less expensive to produce. The same Workshop Controller told me the EGR on the Gen3 was modified (because of soot issues) at the time the car was given a facelift in 2012/13. Interesting as this is, we must remember there are thousands of Gen3s out there that have well over 100k under their wheels with no faults or error codes!

    EGR Cleaning?

    Firstly I'd like to thank everyone for their comments. It's been fascinating and educational. Lots to pick up on but I'll limit myself to two entries: 1) I removed the EGR pipe and cleaned it with oven cleaner. (Thanks for the suggestion.) I've inserted a pic of it before cleaning. Does it tell you anything about the state of the rest of my EGR system? 2) The maker of the EGR cooler is Denso. I found this article about the Gen 3 EGR and you might find the comments (at the bottom of the page) from 'Herm' and 'Eschewo' interesting. Just remember the comments were made in 2012: greencarcongress.com/2012//denso

    EGR Cleaning?

    Tony - yes, I know about the battery fan cleaning. Mine was virtually clear when I last checked. But, back to the EGR. Alll exhausts are 'sooty', just run your finger around the inside of any exhaust pipe! As the EGR is plumbed directly into the exhaust, wouldn't the designers have expected the EGR to become full of soot? And - if so - why isn't there some removable filter?

    EGR Cleaning?

    Tony - at what mileage did your car 'ask' for the EGR system to be cleaner?

    EGR Cleaning?

    I have absolutely no issue with doing (or paying for) any routine maintenance. But the there is no EGR maintenance mentioned anywhere and it's clearly a good idea to have it cleaned out. At a cost.

    EGR Cleaning?

    Fully appreciate all of that. But I expected a Toyota with a full main dealer service history to be trouble free. As my last Prius and two Corolla's were.

    EGR Cleaning?

    QuantumFireball - I'm just comparing my current Prius with my 2004 Gen 2. Sold it with 140k on the clock. Only ever had routine servicing plus a water pump failure. Sold it to someone I still keep in touch with. It's starting to burn a bit of oil and may not pass the next Mot emission test, but it's been a paragon of virtue. And look at the current mileage:

    EGR Cleaning?

    Gerg - a brilliant explanation. Thank you. I love your phrase "the engine will start to diesel". Tony HSD - that video is dreadful. Interesting but dreadful. Seems like getting someone to clean out the EGR system and inlet manifold would be a wise investment. Insurance, if you like. Even at £300 or £400. This Prius is proving to be expensive. Had the Cat stolen last December, so I had the added cost of paying the excess and the loss of many years of no claims discount. Also paid for a Catloc to be fitted. Now an additional £300+. Savings in fuel bills (compared to a non-hybrid car) have probably been erased by these additional costs.

    EGR Cleaning?

    Thanks TonyHSD. The video clip is fascinating and appalling. What is it that's making the dreadful knocking? How does a blocked EGR valve end up making that noise?

    EGR Cleaning?

    Does anyone know: Will the 'insufficient air through the EGR' warning light / fault code appear before it becomes catastrophic? Can i just drive the car, safe in the knowledge that I'll have sufficient warning to get it fixed before any damage is done?

    EGR Cleaning?

    Thanks for your thoughts. I would have hoped the spray cleaners would have reduced the dirt in the EGR to vapour or - at least - microscopically small particles, so it would damage anything else 'downstream'. But you have a good point.

    EGR Cleaning?

    Hi TonyHSD - the car has regular (every 10k miles) servicing using Toyota 0w20 oil. My local petrol station is Shell, so I always use that. I know the best idea would be to clean it but I've seen the videos and I know it's beyond my capability. The options seem to be to pay for someone to do it (£300?) or a £10 cannister of ERG cleaner. Hence my question about the effectiveness of the ERG cleaners.

    EGR Cleaning?

    My 2010 Prius has 80k on the clock. There are many reports on priuschat.com/ of early Gen3s having high oil consumption, leading to blocked exhaust gas recirculation manifolds and stuck ERG valves which leads to blown head gaskets, and wrecked engines when they run over 100k miles. My local (and trusted) Toyota main agent confirm that these failures do occur in the UK. When asked about any preventative measures I could take the Dealer's Service Manager said: " Unfortunately the labour time to clean the valve and manifold is close to 4 hours so it is not included in a service." So, I was wondering, would it be possible to use some sort of solvent? I found many ERG cleaners and here's a few from Halfords and Amazon There's an interesting explanation about the whole issue here from an website in the USA I wondered: 1) Anyone has experience of these: 2) What you think of this simple preventative idea? All thoughts welcome! 😊 Andrew
  15. Can i join this conversation? I've been slightly confused as to what tilt sensor can be wired into a Toyota - for it to work successfully. Eskemoiain says the one made by Hawk Direct works well, but Magooan days the 507 tilt sensor for Python and Viper alarm systems is best. I have the service manual for my Prius (all 8000 pages!) and I've worked out that all alarm signals are a 12v going to 0v for 0.8secs. Can anyone confirm if the Hawk and/or Python/Viper tilt sensors deliver this?
