She's still going strong Peter 20000 kilometres later!! It was a pleasure to deal with you

That’s great to hear Sean thank you

Hi Alan, just seen your video and well done. Am thinking of getting a 6, are they to be avoided or are the engines ok as long as you keep on top of the carbon build up? Any advice would be appreciated. Thanks.John

[@deisediagnostics629]

They have a long list of faults ,head gasket,oil pressure issues,exhaust cam shaft,turbo faults,intake carbon buildup,exhaust pressure sensor issues but a great car when they are going right hard to say what is a good car now they all seem soft now a days

[@johnclaw30]

Thanks Alan, yeah I've decided against it. Beautiful car..it's a shame​@@deisediagnostics629

Unreal stuff, I just bought a mazds 6 2016 2.2 d skyactive, lovely car .I am going to contact you ASAP need advice going forward. Think I know what needs to be got rid of .thanks for your brilliant info.

[@deisediagnostics629]

No bother Mick thank you 👍

[@emanuelDeise]

Great video ! My mazda 6 2017 is idling rough after carbon cleaning. On cold engine the rev fluctuates and when engine is warm it goes away. Any idea what this could be, i also see a bad change in the fuel consumption because of this.

[@deisediagnostics629]

There is lots and lots of faults I see with these Mazda’s could be anything really have you any fault code’s

[@JAO911PLIST]

Well at least you prevented that much carbon from entering the atmosphere as co2. That car is environmentally friendly...

[@265justy]

Not very friendly on your pocket when that carbon fucks up your whole engine and it happens these Mazdas...

[@keithfleck8735]

Hey mate, great video thumbs up. Do you reckon you could do a video on an EGR delete for this engine, and what or what would be your thoughts on doing that. I’ve just bought one of these and curious of good ideas to do for longevity. Like catch can and things too ? Would love to hear from you. Regards

[@deisediagnostics629]

I never done any deletes don’t have the equipment to do them either and I don’t think it’s a good idea if it is done it can make fault finding a lot more difficult and soon I believe that the NCT will be looking at particle matter soot and NOX coming from the tail pipe if EGR and DPF are deleted it will fail watch this space it is coming

[@keithfleck8735]

@@deisediagnostics629 thanks for the reply, I live in Australia and they don’t really test the nox output when they roadworthy each year so that’s one less thing we worry about, but good point on it making it harder to fault find

[@bastogne315]

I have the 2ltr sky active petrol engine....thank god❤

[@deisediagnostics629]

Petroleum is the way to go I reckon

[@happy_forever8]

I got engine check light on and diagnosed under code P0401. Had cleaned the intake & DPF. But after 250miles engine check light on again (still same code P0401) Any suggestion what should i do with?

[@deisediagnostics629]

Maybe EGR cooler blocked

[@sandyande]

That was some amount of carbon, I thought you had been down a Yorkshire pit🤣 cheers sandy

[@deisediagnostics629]

I have seen the intake to be a lot worse than this one but I was happy to see that EGR pipe blocked up 👍

[@pitero01051987]

Hi. If you would live closer to Sligo... I wouldn't mind have a look on carbon at my 2.2 Might I ask how much you would charge for decarbon?

[@deisediagnostics629]

It’s about €680 for the carbon clean

[@turbo8433]

Have you eva come across mazda 2.2 diesel with code p062b ??

[@roberthart9886]

what year... how many miles...gas... diesel...?

[@radugiurgica3501]

Hello, what diagnosis are you using in the video?

[@deisediagnostics629]

It was the Topdon phoenix pro scan tool I now have the Topdon phoenix smart

[@KhanKhan-lw8fw]

Hi mate whats a good reading of a maf sensor on idle on mazda6 2.2skyactiv-d

[@deisediagnostics629]

I’m really not too sure because every scan tool gives me different numbers

[@robertjezinec6467]

Hi! If I clean the EGR and intake, can I clean and intercooler?I think that carbon come from it!?

[@deisediagnostics629]

I’ve only seen the intake manifold and EGR coolers to block up in the Mazda’s

[@JAO911PLIST]

Carbon comes from exhaust gas and the EGR sends some back into the engine because its already burned so it doesn't do anything but expand by absorbing heat and keeping the engine from burning too hot. So the exhaust gases only go through the egr and into the intake manifold. Unless you floor it at the highest gear at the lowest rpm and bog your car down, you wont have carbon build up outside the throttle body. The naturally aspirated 2.5l does the egr function using the exhaust valves. Any deposit there gets burned off.

[@davesterl]

Good one Alan, what year is that mazda?

[@deisediagnostics629]

2016 Dave we are seeing lots of them these days

[@davesterl]

@@deisediagnostics629 ok, reason i ask is the skyactive 2.2 problems with injector seals blow by was alleged to be 'fixed' by mazda in 2016. Fitted thicker seals for 2016/17 model years. I have only serviced a couple that are around 2019's or so but have lower mileage than that one you did. Doubt that will change the carbon/egr issue but I'm wondering of other changes

[@deisediagnostics629]

@@davesterl it will probably fix the problem with the cam shafts running dry due to the blow by blocking oil to the cam shafts I seen Peter change cam shafts on them

[@bartj7066]

Hey, do you think it could be related to the scbs malfunction fault? It always appears when approaching cars at speed on the motorway while engine braking or when engine braking down hill. I got codes p0101 and p0401. I've replaced ehxaust pressure sensor and dpf pressure but had no luck with getting rid of this issue. I'm thinking now about cleaning the egd/manifold

[@deisediagnostics629]

If you fix the p0101 and p0401 with the intake clean the scbs system will be fixed also 👍
