Hi, I am a new owner of a Rav 4 2.2 Invincible 2013, 130k my first Toyota, I have had the car for 2 months now, it was previously owned by an elderly man, who took great care, good history, and he changes all the files and oil before selling, proper old school. I like the car, but it has an issue, a distinct lack of power, the turbo picks up, but then it feels like I am driving in a wind tunnel, it just does not go. I have changed the fuel filter, but it had been changed and the fuel was clean, I have probably spent about £50 on various addd to tank cleaners, no change, and today I replaced the Suction Control Valve, as it seemed it could be the cause, but it made no difference. I have sprayed wd40 around all the pipes it does not appear there is a vacuum leak, but an air/vacuum leak of some sort does seem possible. I have attached images of what I think is the EGR, it seems different from others on Youtube etc, is this the EGR, can it be removed and cleaned (not a mechanic but will have a go) could this be the route of my problem? Please any other suggestions would be greatly appreciated. Thank you    |

That does appear to be the EGR but I am unfamilar with that model - it looks to be water cooled.

Apologies I hit reply before responding, thank you for confirming this is my EGR, being water cooled does that mean I cannot remove and clean or is it a sealed unit type thing and can only be replaced?

I'm sure it can be removed but not sure about the plumbing. Presumably, as the valve is the highest point, once the pipe clips are released and the valve eased off there should be no further leakage. May need the system bled for air and topped up a bit though.

Hi,
Thank you for the information, bit concerned this could be quite complicated,(outside my comfort or ability) particularly if it needs bled etc or if there are gaskets etc, I have searched everywhere to see a video or descriptor for this egr, but no joy as yet, perhaps this egr is not a significant problem, could mean I am barking up the wrong tree.
I may have posted this response twice, apologies if so.

You can remove the EGR without disconnecting the plumbing . It makes it easy to clean the inlet .
But removing the valve itself allows much better cleaning of that part . You could take it to a garage or say a garden machinery shop that has an ultrasonic cleaning bath to get a really deep clean . I have an ultrasonic bath I use for carburettors and lots of other components because it cleans deep inside in airways etc that we can’t even see let alone get at . Normal charge for a carb is £40 but it’s well worth it. Parts come out like brand new inside and out .
I’ve never taken the EGR off my car it’s never needed it so the above is what was passed on to me by a Toyota specialist garage in Worcester 🤙

Brilliant thank you for taking the time to respond, think I will try this over the Weeknd, even if removing is tricky I could at least try and see if it is very coked up or fairly clean, which might help me rule this out as the issue.
Thanks

Thanks EGRs were a pain on the older model ( Mk3) I made up a narrow pipe which attached to a Henry hoover so removing the crud saw it vanish up the pipe into the hoover . You don’t want crap going down into the engine . It’s not rock hard so likely tiny bits would break u and get burned but if your really careful you should be able to vacuum it all up .. |

Ok, I have spent tonight going through various forums, YouTube etc, and I cannot see anybody taking apart this egr, in fact there are few warnings not to touch it as it was designed not to need cleaned. So that takes me back to square one the only code my reader displays is for 'engine lack of power' no other codes at an all. So if it is not the egr could it be the Accuator is there one? The car is fine to drive around town, but I often have to head north Scotland to see my dad, I don't hang around, but the car is not safe to overtake.
In summary, Fuel Filter Changed, New Air Filter, Cabin Filter, New Suction Control Valve, MAF Cleaned, I have sprayed various hoses etc with wd40 whilst running to look for leaks, but nothing, really at a loss. So please any suggestions much appreciated.
Thanks

So please any suggestions much appreciated. Thanks I and Jase on here used to use a Toyota specialist garage in Worcester. The guy that ran it was …..Well let’s say no easy to get along with. But I can assure you his and his business partner’s knowledge was second to none. His dad had a 2.2 invincible auto and I was told how important it was to clean the EGRs as the mileage increased. I was also told how easy it was to do….. Now my car that I bought as an ex demo car just a couple of months old has done only 36K miles. Importantly it’s never been run on supermarket diesel and I’ve used Vpower or added decent additives to keep things clean. Those who know will also tell you that the correct low ash oil is a really good idea. I also never do short journeys…… So I have no need to strip the EGR on my old car. With respect you have a car with a big mileage. I’m guessing you have no idea what fuel it’s been fed or whether it’s been run on the right oil. So my suggestion is take it to a garage that knows and get them to clean your EGR if you suspect it’s causing you issues. 👍👍 |

Hi, apologies if there was any inference that you were wrong, that was never my intention. I will continue to try and find any examples of people removing this particular egr to check for any pitfalls or hints to see how best to do it. Many Thanks

I will continue to try and find any examples of people removing this particular egr to check for any pitfalls or hints to see how best to do it. Many Thanks No need to apologise I may after all be wrong. My opinion counts for nothing its just that my opinion. Though I have been round these cars for a very long time including the previous generation cars we call the 4.3 your car is the 4.4... Previous generation 4.3 cars had huge engine issues caused in the opinion of the two Worcester techs that EGR valve . Main problem being it was very restrictive and coked / carboned up. Hence cleaning the damn things. As above the 4.3 variants did not have water cooling to it EGR .... On here the Facebook page and any other forums the advice has always been to clean the EGRs irrespective of any model or year. If you find something different then please feel free to provide links. I for one would be interested one why you dont clean an EGR valve. Remember while we give advice to the best of our knowledge we simply aint always right and nothing you read should be relied on. We aim to help thats where it ends . |

Further Update - Would seem cleaning the EGr has made no difference to the lack of power, did over 150 miles, various roads, no improvement, aver 30mpg, which is not great, really disappointed, don't really know where to go to next. perhaps I should have forced the flap/valve open, will try and get a garage to look at it this week.
