This guy deserves more subs!!
😂Thanks bud!
Very underrated for sure
Carlos Roberto Yes! He is one of the absolute best on youtube! Totally love him...and the content :)
Solid diag. Like a real pro ! Thank you for bringing us along 🙏
As always Mario GREAT video! Thanks for sharing! I didn’t know you could isolate the intake like that for testing. Appreciate you bringing us along!
Really cool vid!! That’s why you’re Super Mario!! Three steps to the conclusion. Thank u!!
Man you have become the teacher instead of the student in a short time.
Thank you Mario. Good job. Have a blessed and safe week.
Outstanding job Mario! I never fail to learn something new from your great mind and detailed videos!
Thanks for sharing this with us and the information about Steckler classes online😉👍
Keep up the excitement and great videos!
Thank you Mario. Great Diagnostic Video
Great video Mario! That scope made viewing those valves effortless! Thanks for sharing!
It doesn't get better than that. Great quick diagnosis and explanation 👍
Bravo. That was spectacular👍👍👍
Great job as always! Keep it up. I definitely got to take Brandon's class to understand better.
WOW, what a quick and good Lesson ! Thank you !
Nice work brother. Seeing this video made me realize I bought the wrong boroscope 🤦♂️. Keep the videos coming bro
And there’s the reason why this guy is Super!! Great find Mario!!
Mario, great video !
One other reason for a manufacture to deactivate injectors in a cylinder would be for catalyst protection.
True! That's why i need to constantly return to the classroom, i tend to forget things 😆 thanks for watching!!
this is why having a pico is great... just need to learn the one i bought.. this was fast and effective diag..
Awesome!!! Now I need more tools…. Bore scope, scanner, etc
This is cool, I have had Minis with loss of power before and they present after a tow in with a fuel gauge showing 1/4 fuel and also an unsteady crank, the fault I have found is the tank has actually run dry and the gauge is showing a false reading that it has fuel, the engine has run lean and hurt piston(s) because of running lean.
Mario,another great video. Nicely presented with a very good troubleshooting approach. Thank you for sharing. Can you send a link for the borescope and the bellows plug. Thanks much. ❤️
Thanks Arthur! It's the ME-610 from oasisscientific.com

Thanks for sharing. Awesome work!
Hi Mario, valvetronic opens one intake valve on lower load cycles like start cycle, then in more load, open the other progressively, but in the video from the endoscope seems like the seat is completely messed up. Nice video, great content, instant subscribe!
This is one elite diagnostic video sir.
What do you call SUBSTANTIAL and KNOWLEDGEABLE the answer is Super Mario Diagnostics Amazing tutorial video Brilliant fantastic 🎶 🎵 🎶 🎵
God bless you and all your family around you. Bottle of water 💧 very good for your body👌👍 Super Mario Diagnostics
From Nick Ayivor from London England UK 🇬🇧
I love these ones! Good work bro! I’ve got that borescope on my list
Well done my friend.
I love the video
Fantastic job Mario, way to go "working the mind a bit and stick to the theory" keep it up brother!
I went to Brandon's class for the 2nd time @ Vision, well worth it.
Wow that looked so straight forward, i wish I Will bé such a diagnostic soon, too. Thank you Mario
Wow you are thorough. Good man. Very clever.
Fantastic video learning a ton, just got my pico and been learning a bunch with it.
I hope he decides to fix it, that would be a fun video to follow along.
Thank you for your help, finding a misfire cyclindér
Excellent video Mario! N series engines are famous for dropping valve seats especially if overheated or right after machine shop work. At 13:50 you said there's no reason why one valve should be open and the other isn't (obviously speaking about the intake valves). As a matter of fact there is.
These engines control the idle speed by altering the valve lift via an eccentric shaft and the eccentric shaft motor (valvetronic). The eccentric shaft has two lobes per cylinder (one for each valve); the lobes have different profiles. So, at idle, only the front (timing chain side of the engine) intake valve opens. The second intake valve doesn't open until the eccentric shaft hits approximately 150 degrees allowing more fuel and air to enter the cylinder ... more power. If there is a malfunction with the valvetronic system; the DME will use the throttle body to control idle speed as a secondary strategy.
So when you scope a MINI N series engine; the position of the two intake valves will depend on the eccentric shaft position. If you want to set the eccentric shaft to zero lift, use a 4mm hex bit in the back of the eccentric shaft motor and rotate it counter clockwise until you hit the stop. This will put both intake valves in each cylinder at the fully closed position.
If you pull up live data, look for the eccentric shaft position under the Valvetronic or valve gear menu. If the value is < 150 degrees; the two intake valves will be in different positions.
The valvetronic system controls both intake valves at the same time, always. Not just one valve. That’s why the valvetronic system directly controls engine rpm. If it only controlled one of the two valves, it would not control the rpm of the engine. Hence there is no time where only one of the two valves should be open on a properly performing engine
I’m gonna dig more into this. I’m looking for documentation on it but don’t see it. Next time i have one open I’ll confirm
@@SuperMarioDiagnostics It's not well documented; I found this fact when I was troubleshooting a cylinder 2 misfire on my 2009 N12 MINI. In my case, the misfire occurred because the valve seat had dropped more than the valve lift (valve was not opening), so no fuel/air was entering the cylinder. The cylinder was actually under a vacuum when the piston was on the intake stroke. As you know, when you snap the throttle while monitoring the secondary ignition wave form, the KV line will increase due to the increase in combustion pressure. Conversely, when there is a vacuum in the cylinder, the KV line will decrease, and that's what I found on the scope.
Once I had the cylinder head disassembled, I put a Starrett straight edge on the lobes of the eccentric shaft while rotating the eccentric shaft motor manually. That's when I found the lobes between the two intake valves on a single cylinder are not symmetrical; they are staggered; the shaft has to rotate more before the second valve will begin to open. I've got a picture of this, but there's not place to upload the photo here.
@@superk4562 I’d like to see it, mind emailing it to me at supermariodiagnostics@yahoo.com
Great video as always mario,
Like that little tool for removing crankcase breather hose , not seen anything in uk like this.
Another awesome video. Thanks for sharing Mario 👍
Awesome diagnosis and great information!
Muy interesante Mario exelente
Mario thanks for your time and sharing..great video..
Customer complaint, dying. Haha, was dying the day it was made. Thanks for the video, as always was very good.
great diagnosing a misfire great job and nice video
Thank you!
Good job 👏
SUPERB! Thank you Mario
welldone sir.an exellent diagnois.
Great video as usual Mario!
Wow thank You for share Mario !
Looked like it bent that valve lol love the vids man I'm a class diesel mechanic and i use alot of your vids to help me diag great stuff 👍
What a beast!
Nice one! Keep em coming! I need all the pulse sensor videos I can get. I also need that borescope. My autel one has worked great but when it comes to looking at the valves that one you have is amazing!
Very good video!! Very informative! 👍thank you !
Excellent excellent video Mario. This is the deductive reasoning everyone should be using. Great job brother! Stick the wps in there for practice for me next time 😂😂 thanks for sharing this.
great diagnosis Mario Definitely saves a lot of time !
Great as always thanks for sharing your knowledge
Really good stuff. I’m hoping I’m not at DefCon Four of repairs. I just got a 2007 S and I’ve got a cylinder misfire issue. Stay tuned. Thanks!
👏👏 Fantastic! Beautiful job!
El mejor 💯
Its a NA engine, these ones also have variable valve lift. If you do get approval for the repar. Make sure you check the excentric shaft for wear. These ones wear out alot and you end up with a bad idle or misfire at idle.
Super smart!!
Nice job 👍👍
These cars have many problems
Injector cut for a misfire also saves the cat ;)
Great work big man!
brilliant sir.exellent job.
Great video, Just ordered a clone can't wait to use it, I've wanted one for while now, but couldn't find them that cheap.
Excellent video. I’m going to Brandon’s class in May. I will have to watch your video on the borescopes again, that seems to be faster than doing a leak down test.
Yeah i just bump the starter until the piston is down(50/50 chance it's on compression), makes short work of this
Another excellent video. I have to get an articulating scope. Beats the heck out of using a mirror..
Thanks for your vídeos Mario they help me a lot!!
This video is good I learned a lot thank you brother
with that valve staying open would a comp test not have showed a significant drop? wifes 08 today had a misfire code on #2 - comp test hit 180-190 on all 4- now it wont even start (sounds like your vid - cranks but doesnt run). All 4 coils had exact ohms across the 3 pins... Although I did leave the coils plugged in hanging near the exhaust shield when I did a comp test - hopefully I didnt blow anything? Also disconnected batt for 3 hours to reset ecu - thoughts?
Very common on N12 engines. I had few similar issues valve seat broken due to overheating. It’s repairable with lots of labor involved.
Great explanation
Another Great Job.
Well done buddy.
Thanks for Sharing your Knowledge Mate :)
Nice. Great video
If you think about it if the PCM detects a misfire it will turn off the injector to pervert cycled wash and oil dilution and catalyst damage
I learn something new with each one of your videos. Thanks. Now, how about links to where you got the small bladder and the disconnect tool?

Thanks Pauly!!
another cool video. i will have to watch it again cause i got a bit confused on the explanation with test procedure . also will check if there is a part deuce..
Thanks! No there won't be a second part to this video. Customer declined going further
really interesting, good job
Great vid as per usual! As far as I can remember (was a few years back) I did an engine rebuild on one of these mini’s a few years ago for a similar misfire issue but we used the cylinder leak down check to find the issue after doing the oul plugs/coil swaparu trick. I’m sure we ended up also pulling pistons and rods and replacing the piston rings too...! To be fair the are a complete POS engine !
training pays off.good video , i think they cyl deactivation is to protect the cat.
Hi, I have a problem with my Mini Cooper s r56 not start.
The only code the mini have is: A0B4
The mini was on taking it out of the garage when it suddenly turned off. The first Scanner have these codes:
2781
2775
2D52
*2DCA*
275F
272F
I changed 4 spark plugs, 4 coils, the Camshaft Position Sensor and a new battery. But it did not turn on, now it is giving these codes:
005E31
009314
*00A0B4*
00932D
009CB5
I deleted them and it only gives me this code: ( A0B4 )
The mini starter good but not start.
I try the new battery and it says it's ok, but when I test the battery with the terminals mounted on the Mini Cooper it says it's bad I don’t now why. I also reset the new battery in the mini system with the scanner but nothing.
( A0B4 )
Good job Mario. One question, does your borescope have a mechanism to control the bend? I'm wondering how you got it to point back up to the valves
Yes, it's the ME-610 from oasisscientific.com
@@SuperMarioDiagnostics Nice. Thanks.. I've managed to roll mine back up once or twice stabbing at the corner of the piston and bore, but, it's a pain. I'll have to look into one of these.
Any ideas for a gas tank SAFE borescope that is affordable?
Honestly i couldn't say, you may want to reach out to someone in that site.
They may be able to better help you.
@@SuperMarioDiagnostics Thanks for the prompt replies and the great channel!
Love it Mario
Found this video because I was thinking of buying a Mini for $1500, but the owner says it has a misfire. Does anyone know how much the repair in this video can possibly be?
Great video Mario, I just subscribed
I hope you are doing well and safe in this pandemic situation ,take care buddy
Hey Mario I also have a 2007 mini cooper base model and the engine light came out a few weeks ago, my car turns on good and I can driving it for e few miles like to work and to some stores around my area but sometimes when I come to a completely stop my car will suddenly turn off, is not all the time just every once ina while. Do u think I could have a misfire? And how much would it cost me to fix it? Thank You!
Has anyone ever had problems after your mini Cooper gets to normal temperature and starts to misfire or when you come to a stop and start stuttering and seems like it wants to shut off ?
Genio
This was an amazing diagnosis my friend. Well done. Thank you for sharing this case study with us . Cheers.👍👍😁
Found your channel from WatchWesWork.
Can you fix my car Mini Cooper 2010
Engine on, and cylinder failed?
Can all the scope tests be done easily with snap-on zeus??
Was the other inlet missing a little of the valve rim too?
Nice video
Nope that was intact
Can you please share the tool info you use to remove the valve cover breather hose?
OK MARIO THAT WAS OUTSTANDING , NOW I CAN'T MAKE IT TO BRANDON STECKLER CLASSES THERE MUST BE SOME BOOKS , CD'S OR ONLINE PRESENTATION BY BRANDON STECKLER THANK YOU AND COULD YOU LET ME KNOW IF YOU KNOW IF THERE IS AND THANKS AGAIN .
Tst seminars has online Steckler classes, check em out. Thanks bud
MADE MY DAY BIG BRO !@@SuperMarioDiagnostics
Thanks for sharing this with us Mario!
Good to see others believe in going to training!
Great vid. Which note scope are you using???
Thanks! The borescope is an ME-610 from oasisscientific.com
I HAVE HEARD IF THE PULL IS GOING VERY HIGH IN THE WAVEFORMS THEN IT IS AN EXHAUST VALVE LEAK INTO THE INTAKE MANIFOLD AND IF THE PULL IS GOING FURTHER DOWN THAN THE REST OF THE CYLINDERS ITS AN INTAKE VALVE LEAK JUST BASICALLY . I HAVE WATCHED YOUR VIDEOS AND BRANDON'S VIDEOS BUT AM NOT SURE ON THIS POINT WAS HOPING SOMEONE COULD SHINE SOME LIGHT ON THIS FOR ME THANKS MARIO .
I love the strategy work from mind 😍 , during my intial startups I didn't mind of getting dirty from mechanical job when days passses It started deserve doing the job without dirty 😂 obviously I have to diagnose from therotical basis instead of remove fixing back blah blah
what boroscope are you using? Edit: I read other comments and found the answer.
Never seen that tool for crimping the CCV hose, can you provide a part#? I work as a BMW technician and we all use pockets screws drivers.
Snap on, matco and cornwell all provide these, i don't have a part number. But it's name is "pcv/breather hose remover"
So nice! Great job! i have 2007 1,6 120hp , same problem , after few coil and spark plugs swaps the car went worse...didnt have time to check injectors..Is there a way to diagnose the injectors?? Cuz i dont want to go straight to valves etc. Still looking for a good mechanic in my region.
Why not rule out engine mechanical before anything else? It's the most expensive repair that you can check in no time
@@SuperMarioDiagnostics i will try best before buy and change anything. How about ECU? Ive heard it could be defective, but dont now how to check it.
