Mate, im forever grateful for people like yourself that upload ransom vids like this. Unrelated to your issue, but the little plastic 'junction' in the cooling circuit shown in your vid at 9:26? Yer that gave out on me and as you are aware a total pain to get to. Mechanics all near me are booked out for a cppl weeks. Will he replacing myself and seeing a complete teardown to gain access is going to help heaps. Also, for others watching this, mazda have since replaced the part with solid metal tubing. Much better.
Thank you very much for you input, I really appreciate it ;)
Great video, its Sunday and I'm ready to do this job on my car. Thank you for this video, gives me confidence.
I am glad it will help you to get this job done on your own. 😉✋
Bout to do a manifold clean on a 2010 2.2L mazda 3 diesel and stumbled upon this video that may just help me :)
I bought a diesel for myself, now I have to clean it, oh and it’s a lot of fun)
thanks for your video!
Nice job mate! Very impressed.
Thank you buddy.
Really glad of this, thank you. Can see me coming back to it (especially going back together) when I tackle mine.
Got a lot of smoke on idle and boost too. Worried I'm staring at a turbo and maybe cam too. Love the car though
Did this job at the weekend. Thanks to your video it made it so much easier.
Question, did you have any trouble restarting the car afterwards? When I came to restart mine it struggled for a long time. Could it have been excess cleaner left in the intake and valve ports?
It's ok now, but had me worried for a while.
I did, took about 10 goes to start. But now my mazda has no power under acceleration so not sure why
Great job and thx Mate. Your video helps a lot.
I followed precisely all your steps and after 12h in 2 persosns we succeeded to reinstall everything as it was before.
The problem is that the board is full of errors as a Christmas tree 🎄, the car is on limp mode one without turbo running.
Canceled all the errors via diagnostic module but without success, the errors are there.
I did something wrong?
Thx for any suggestion because we made this operation just as prevention, the car hasn't any error before 😢
Do you got rid of your problems? - I'm a bit afraid that my Mazda will be the same?
Do you have any tips? - I just have a very cheap diagnostics tool should I get a expensive one before I do this repair?
Thanks - Greetings
@@chris-qc7eu I solved it but other problems pop-up (e.g. DFP). I suggest to do this operation with somebody who did it already. Mazda CX-5 diesel is a complicated car, unfortunately
Love your video, I think I will have a go at my car now.
Sure, it is fairly easy and straightforward job.
Great video! Did you reuse the coolant? Any advice before starting the engine after assembling everything back?
Thank you! I didn't reuse the coolant I just topped it up with distillied water, but technically you can reuse it. However if it's old it's worth flushing😉
Well,here is an advice, if it doesn't start you may have to jump start it. Or you can make sure that when you clean the intake ports,the valves are properly closed and no deposit gets under the valves making it harder to start.
If you have any further questions,please don't hesitate to ask them! 😉
Thanks for the advice. I'm planning to do this job shortly. Another question would be if you changed the gaskets with new or re-used the old ones. Thanks.
If it helps, for manual transmission, the engine can also be rotated by switching to 4th gear and turning the driver's front wheel while the passenger's stays fixed.
@@vrabievalentin4071 I only changed the intake manifold gasket and the throttle body gasket, because only they were available to buy separately. For the EGR valve,piping and EGR cooler I reused the old ones, becuase I couldn't get them. But maybe I was just lame :D and didn't know where to look for them.
Yeah, I know about that technique, actually I have a video about it as well. I don't know why I didn't use it, would be certainly easier. But it is what it is. The car is fixed now ;)
If you follow the video step by step you should be able to tackle this job with ease. It is quite simple and straightforward, there are just million bolts and screws to remember where you have taken them out from :D
If you will need any help, feel free to ask it ;)
Couldn't help myself so I stopped work and started this job on my cx5 at 3 pm today. I managed to remove and clean the EGRs, egr coller and bypass pipe. Had a try to remove the manifold pipe, the one at the bottom. I rotated the plastic connection anticlockwise but damn, could not remove it. I'll try again tomorrow after breakfast.
Quick question, is it necessary to remove the glow plugs while cleaning the engine side?
Hi! Many thanks, great video. Was the code p0401 the only problem, no leaking egr? I’m asking because my problem is the rising pressure in the cooling system. It keeps filling the expansion tank. Cooling fluid won’t get back to the radiator when cooling down. There is a bit bubbling in radiator when app 3500rpm. Oil and cooling fluid don’t get mixed up. So I was wondering if egr leaks to the cooling system?
Car is model 6 2013 2.2diesel 175hp and 300000km driven.
@Janne Kallio Thank you. It had only the p0401 code. Well I think the EGR and the cooling system are connected so they can't leak to each other as they use the same coolant. I would check the thermostat if it is working, or would replace the coolant and then bleed it.
However at 300k km I would definitely clean the EGR and the intake manifold from carbon deposits if it hadn't been done.
Could the exhaust gases be leaking from the gas side of the EGR cooler into the coolant side?
@James Campbell Yeah that could be the case. But obviously that has to be checked by a mechanic.
Janne Kallio thats amazing to reach 300,000kms. Was it the original engine? I had mine replaced at 125,000kms due to issues with the overactive dpf.
@@jack_attack_1 yes it is the original engine. Turbo was replaced already in 30000kms and the other camshaft in 230000kms with nozzle gaskets and the oil strainer. But now I got the cylinder head gasket replaced and the turbo for second time. There was a minor leak in head gasket.
Hi followed the step to step guide, need a advise please. Got the EGR, throttle body, MAP sensor and manifold cleaned yesterday.
It's for Mazda 6 2.2, 65 plate (2015). 71000 on the clock. Car started after cleaning, smoke came out of exhaust and got cleared within 5mins. Car was perfect on idle. Done the coolant bleed and filled the coolant.. Car was running for good 45mins on idle and heating working fine
Took it for drive, power was back and felt smooth in every gear and no shakeness felt in flooring it
The turbo was spooling can hear the turbo on the way home from good 25mins test drive
2nd time 4 hours later I went for the drive to the town and back 30mins drive, car was good and smooth and picking nicely in gears
2 hours later went for drive for 45mins and got to inside roads and notice could not hear the turbo or turbo spooling and speed wasn't picking up after gear change felt slight delay and could not hear the turbo what could be the issue??
Need little help with turbo as I do not hear the turbo spooling and delay in pick up speed, at the moment no engine management light
Could it be issue with MAP sensor as it looks worn out? Gave the MAP sensor a good clean. Or any other sensors I need to check or clean?
Thanks
Try to check and clean the Exhaust Pressure Sensor. It's on the top rear side of the valve cover under the sound isolating shield.
@@MrNiceGuy94 okay I will try that. Is there a sensor near the turbo area near the intake pipe? Also Is there a electrical control solenoid that needs cleaning or replacing and where is it located?
Bought a 2016 cx5 2.2 skyactive last month and only just been told of the potential major problems that can arise. Am I driving a ticking time bomb?
Well, if you will take care about it you shouldn't have any issues.
But it's true that it needs more attention on the maintenance side.
Why the hell do these engines 'carbon up' so much 🤔
I wish i knew this before i bought one.
P.s , is that throttle body spray you were using ?
They have a bad design from factory. I used EGR cleaning spray.
Classic
I followed your steps in detail and cleaned intake manifold and EGR.
When I put the parts back together, car started first time no issue. No codes after test drive.
However there is little power when I accelerate (which wasn’t there before) as well as a loud whistle noise. Car struggles to go over 3000rpms. No other engine light has come up.
Have you had this issue? If so how do you fix?
Update to anyone who is having P0401 code in Australia.
I have a 2017 Cx5 Diesel, same engine. With 140,000kms
I followed these exact steps and it’s my first time doing it.
The issue I was having was due to 2 hoses that weren’t clamped properly and low coolant levels. Found out by doing a smoke test. And saw the engine over heating.
This job took be 20 hours over 2 days. Personally I would not do this again on my own. I found a mechanic who will do it for $1000AUD in Australia. And they were willing to do an ultrasonic clean for the EGR AND Intake manifold and a walnut blast for the engine bay. A much better job Then what I could ever do with a screwdriver and carb cleaner.
This is a really hard job that can be done, but will take a long time and at least 2 people. But if you can find a mechanic to do the job I would recommend going to them as they will have the resources and better tools to get the job done better.

Thanks for the video. Is there a way of knowing if the intake valves are closed on an automatic transmission without using a borescope?
Hello. The transmission doesn't matter. Other way is to remove the glow plugs and use a screwdriver and with that you can check when the piston is at the top dead center. However in my opinion the borescope is a lot better, because you can see it, and also you can have difficulties removing the glow plugs.
@@MrNiceGuy94 Thanks a lot. I'm changing my cylinder head gasket as well. I'll take that as an opportunity to clean the intake and EGR system.
Hello and I respect you to do this operation we need to remove the battery?
I want to give it a clog cleaning as well
after this operation you had to put the device to the test to cancel the witnesses?
Hello. Yes you need to remove the battery. Unfortunately I don't understand the second part of the question. Could ask it a different way? Or Ask the question in your language and I will get it translated.
Am I seeing this right... ? for s simple EGR removal and clean u have to take off that many parts. that many nuts,bolts,sensors and wires,hoses ??? How on earth will u remember to put it all back let alone correctly?
Yes,you are correct 😂
One example is to record everything you have removed and then watch it back when assembling things together.
Second example is to use my video as a guide. 😉😂
@@MrNiceGuy94 haha top guy so true! just record it simplezz
@@princejamil87 Yeah,recording it definitely helped me as well.
What is the hose you remove at 0:39?
air box vacuum hose
after installing the parts in their place that were cleaned, you used a special tester to erase the errors from the car's dashboard ?
Yes,a diagnostic tool.
Szia, észrevettem, hogy magyar vagy Angliában, vállalsz ilyen munkát még? Van egy Mazda 2016 2.2 dieselem.

Hello, I would like to ask if you purchased new inteake manifold gasket or used old one ?
Hello, I used new intake manifold gasket for this. However I did put old gaskets back for the egr and piping as I couldn't get new ones for them.
I just got my Mazda 6 back from the mechanic yesterday after having a new Exhaust Pressure Sensor installed and then today I get this EGR fault. Are these two related and should the mechanic have spotted it when changing the EPS?
Hello, I have done the Exhaust Pressure on this one a few weeks ago. I am not sure if they are related. But it is extremely likely that your intake manifold,intake ports and the egr and cooler looks like this one.
I would recommend people with this engine that they clean it every 40k miles at least.
Hi MrNiceGuy. Thanks so much for your video and great job with this project. Can you tell me if your car had any other symptoms other than the fault code? Did the car drive poorly? For me i have trouble starting my car (like the starter is lazy or underpowered). Its worse when the engine is already warmed up. but once the engine is started it drives normally. I have no fault codes and i have tested the battery - perfect and the cable connections and starter motor appears to be ok. Just wondering if its an early sign my car is starting to clog up with carbon deposits? Thanks again
@Jack Foo Hi, it was a customer's car. It had the fault code, and he also told me that the car drives better than before, more likely was running poor because of the carbon buildup.
Well, with your problem it could be the starter as you think or the carbon buildup as well. If it gets to the valves, it makes the engine more to turn over when starting.
You can easily check if your car needs a cleaning. Just remove the MAP sensor off of the intake manifold and inspect the end of it. If it is dirty from oily carbon residue, you 100% need the get this job done. Also I would recommend doing it every 40-50k miles on this engine.
Hope this helps! ;)
@@MrNiceGuy94 thanks again. What you say makes sense. I will try to eliminate the easier causes before tackling this project. I remember i pulled off the map sensor to check shorty after mazda replaced my engine. I did find alot of carbon deposits choking up the sensor. Makes me wonder if they bolted everything back including the manifold without cleaning it. So far my car has done 50k kms since the engine replacement.
@@jack_attack_1 They may have cleaned it, but it gets dirty quite fast. I would definitely get it cleaned. Honestly it is not a difficult job at all. You just remove bolts and parts then clean them, and finally reassembling everything. If you follow my video it should be an easy task.
Hi I'm a bit confused on the whole egr system I'm trying to block it off and was told to just block the solid metal pipe labeled 1 and 2 off closest to the engine ,would that work?
To be honest I am not quite familiar with EGR blocking. I think that you need to block all the pipes which are going from the EGR system to the intake. But more importantly it has to be written out of the ECU as well.
I can do this operation of washing the clogged elements without using a car diagnostic ?
You don't need a diagnostic tool to do the cleaning.
have you used the car diagnostics to cancel the error code stored in the car computer?
I think yes.
CHECK ENGINE deleted from the car dashboard with the car tester?
Yes
i did same job as you but i didnt use cleaner for valves, i used thin brush and cleaned with it took more time but i did do the job now i have problem with car not starting did check batty voltage and it is at 12.4 and when i crank it it is at 10.30 10.40 but it starts to crank and after 2 or 3 sec it starts to missfire it throws bunch of codes that i did clear but i trie it agean and have sam codes i need to check all conector main bing the throttle body and some sensor in the middle off engine block down ther i think it is cylinder recognition sensor
Hello, is it manual or automatic? First I would definitely check again for all the connectors if they were properly reconnected.
However we had problems to start the car as well, we had to push start it as probably a few bits of carbon deposits were stuck around the valves and made it harder for the engine to turn over.
Let me know if you succeeded with it anyways.
But as I said, first I would check for the connectors then trying to push start it it it's manual.
@@MrNiceGuy94 it is manual 2.2 150hp, i can try to push start it but i think i will get one more battery and start sprey do you recomend it or is it batter to push start it
@@filip-pi9hy first I would try to push start it if all the connectors were checked, and if it doesn't start then I would get a new battery.
@@MrNiceGuy94 did test connector all are ok when i turn off ignition i can hear intakeflap working i will trrey to push start it
@@MrNiceGuy94 car started with start spray small amount was all i took to start it 😂 now it work relly good and pulls 100x better
Delete the bloody egr. Engines should not eat their own waste.
hi can you fix my car's EGR
pls
🙏
Hello, i made the big mistake and let egr fluid in the cylinder :-( Motor will not start. How can i correct my mistake? With Carbon X Combustion Chamber Cleaner K1+K2? I already removed the glow plugs and turned the motor over. Nothing came out and it did not help!
Hello,
did you mean EGR cleaning fluid? If so, what might have happened that carbon deposit is stuck on top of the valve, and therefore it can't close properly so you have compression leak and that's why you can't start the car.
It happened to me as well.
Is it automatic or manual?
Yes egr Fluid. That is exaclty my assumption ..it is manual..i am trying to remove the deposits teeth brush
Well, you are lucky then. As if you said that you have removed the glow plugs and turned the engine over so that way you made sure nothing is inside the combustion chamber.
So what you can do is to ask someone to tow you and that way you can push start the car.
Whilst someone is pulling you with their car, sit in your one have 3rd gear engaged and the clutch pedal pressed, and when you are rolling release the clutch pedal. Just be very careful that you don't crash into each other whilst doing it.
Hi again,
so i cleaned up the valves one more time with oven cleaner...it helped very much and then crancked with glow plugs Out and reassembeled everything. Engine Starts now but very loudy..so will Change the oil tomorrow and drive a little bit ..
I am glad it fired up finally. A rough idle or running is pretty normal on the first start up, even some smoking from the exhaust is normal.
Hello, I also have the same problem, error P0401 turned on on Mazda 6 2016 2.2d, can I come clean the egr???
