This is great. My Mini spark plugs had to be replaced but the check engine light never turned on. It felt like the car was jerky, like it was dying out. You explained it very well. Thanks!
Liked this a lot; you have a lovely presenting style, easy to understand and I'm so glad you don't talk at 100mph like lots of other RU-vidrs. That handful of old valves shows you're not afraid of getting your hands dirty too! New sub 👍
2012 Mini Cooper Countryman base had misfire with codes on cylinder 2 and 4. Replaced both ignition coils and problem cleared up. I did do a resistance check with a multi-meter against the new coils and all coils came back as .06-.07.
every time I have an issue with my R56 I always find myself referring to your videos. I'm currently dealing with a traveling misfire that started on 1 cylinder, then it jumped to 2, and then finally when I was able to baby the car 45 minutes back home it plagued all 4 cylinders. My brother and his best friend swear up and down that it's just bad fuel but my girlfriend and I got fuel from the same station within hours of each other (both turbo cars requiring premium-91/93) and she never had any issue. I've got just over 80,000 and I'm convinced that the fuel filter has probably never been changed, and the HPFP, from what I've researched, can fail pretty early on in the cars lifespan. So my plan was to start with the filter, do a compression test, and then get some injector cleaner to see if that can help revive my mini that has been sitting in my garage for the past 5 months untouched. Then once I get everything sorted I'm in dire need of a walnut blasting to get rid of all the carbon build up.
Thanks so much for the video! We just replaced 3 of our spark plugs and they were all disgusting, however we can't get the 4th to come out. The car was and continues to misfire and act "jerky" when first warming up. Once up to temp it runs fine. There is a check engine light quoting multiple misfires. Could it be the coils? Or the last spark plug? Running out of idea's :( Please help!
Great video thanks. I have a continuous misfire on only one cylinder. I'm worried it's a mechanical problem but I instantly got an engine code. I'll try swapping a spark plug and coil to another cylinder.
Liked your vid. I am currently experiencing that very same thing. Gonna take it into the dealers. I have a 2012 countryman. I love my car. I watched your videos and learn a little more about what these warning and error codes are and how to go about getting them repaired.
Great informational video. I have a p0300 and p0303 misfire code on my r56. I recently replaced all four coils packs and still the problem and codes exists. I checked all four spark plugs and cylinder 3 spark plugs has oil on the tip. My next step is to replace all four spark plugs, I recently purchased my r56 and the previous owner said he never changed the spark plugs.
I have idle misfires on all 4 cylinders randomly after valve job and head gasket replacement. Checked compression (N12 2010) 200-210 all, new plugs, new VVT solenoids, checked intake, it is tight to the cyl head. Runs beautifully at 2000 on up.
hey mate. really like your channel. I have a Audi and have been doing some work on it myself, saved loads of money. going to change oil vacuum and and some other things soon. any way respect mate. subbed
@@CraftyWorkshopBuilds Thanks for the reply. I have a b7 audi fsi, I have a small youtube channel, the one I'm using, have a look if you like, you might like 👍 I'm going to coolant temp sensor, oil vacuum pump and cam shaft follower, and also rocker cover gasget as I did it recently but starting leak again, think it was because of a pcv delete? what you think? 👊
Excellent video. I have an '07 MCS that was diagnosed with a burnt valve. (after it was running so well!) The shop did not want to repair it because the car has 197,000mi. How do you feel about it? Worth saving? Thanks again!
It all depends on how much you like or want to keep the car. If you do decide to go ahead and fix it, might as well address any other possible issues within the motor. After that it should be pretty solid.
2010 R56 S 95k miles. Had the car for 7 months and 4k mi. New (real) NGK plugs on 7/20/20 82800mi, good gaps still. NO CODES. Data logged with Bimmerlink when cold each time. In the last couple of weeks I have had a misfire when cold on plugs 1-2-4. I have obtained a used set of coils (?mi) and swapped them out 1:1 from the other car, I will spare you the swapping details going forward but nothing changed. I have swapped plugs around and nothing changed. The hesitation and missing is very slight is more pronounced when cold but imperceptible when warm. Misfire happens at highway speeds. The HPFP will get down to 550psi at 122deg misfire cyl 4. but will get to 550-700psi when cold with cyl 1-2-4 misfiring. The misfires on 1-4 also happen at 1200-1600psi with the temp at operating. I do not know the status of the fuel filter but always use top tier fuel of Shell/QT. Complicated huh? Yeah I know its a problem child/mini life. Going to Mini's on the Dragon in 1 week need this sorted. missing happens on all cylinders, all temps, any time. Just more pronounced at cold.
Hi. Thank you for your video! My 2009 R56 eventually misfires when I’m accelerating hard. Already replaced the ignition coils, compression is good, and idle too. What would you suggest?
I have a question for you I have an 09 Mini with 1.6L turbo. This car has a miss fire under 2200 RPMS. Has new coil pack and plugs, all 4 cylinders has 175 psi compression, has spark and injector pulse, fuel injector is good. When driving with scan tool hooked up the miss is not present above 2200 RPMS or so. I have removed the valve cover to check the valve train for broken valve spring, rounded lobes on cam all is good there as well. I looked up the timing procedure while the valve cover was off to check the timing as well, the cams seem to be in time ( I do not have the special tool for timing ). The actuator on the intake cam does not match the position of the exhaust cam. Does the actuator position matter on this motor. There is no mention of that in the timing procedure. This is a used car so I have no history on the car other than when I had the valve cover off the timing looked brand new. Any help would be great.
I have occasional white smoke coming out of the exhaust, usually in between shifts. Could it be the PCV membrane, or the turbo beginning to fail. Thanks for the great video. I’m going to check my membrane for holes/damage.
@@nanolure8678 The car is fun as hell. Replaced full valve cover unit, turbo still strong! I had a oil pressure switch that went out at the same time. All good. We rollin’!
@@precool Yeah, I totally agree. Have a couple now and rebuilding engine on one. Those miles, great your turbo still going strong. Good luck with it, most smiles per miles.
Great video thanks! I have a misfire on the #3 cilinder but only after warm up . In cool conditions works good. Checked compression and all are around 130 and very close each other. Some other method to test? Thank
Hi yes I have the 2007 mini cooper which is throwing up code cc id 031.. Runs sluggish for a couple of minutes then ok. Engine light on.. I've replaced the fuel cap for a new on..
Can someone help me out ! So here we go got a misefire cillinder 4 ,puts on check engine light .. Weird thing it comes and goes .. Mostly when idling stationary check engine starts blinking amd can feel the engine off balance (misfire 4) got a r50 2006/07 1.6 petrol .
I parked our Mini at the airport for a week. There were temperature fluctuations from freezing to plus 50 Defender. After getting home, the next morning it backfired and popped until the car had been driven about 20 minutes. Any thoughts appreciated
Thanks for the video, helped me understand the common issues with my R56. I installed upgraded coil packs, upgraded plugs, air intake system, and im still having issues somewhere. i believe it might be my fuel pump, i cant hear it priming the line anymore and it takes about 6 tries to start the car. it also has a rough idle when i finally get it running. if you or anybody else has a better idea of what it might be im all ears. Thanks
There’s two fuel pumps too the one in the tank and the high pressure one I had issues with the one in the tank after I already replaced the high pressure one
thanks for the great video, my 2011 initially had misfires on cylinders 1/2 due to the valve cover leak on wells(1/2), replaced cover gaskets and all spark plugs and coils, but the cylinder 1 still has misfire, so I switched around the plugs and coils, still cylinder 1 misfire in low rpm mostly, any idea?thank you
Sir, thanks for your help. I have a 2008 R55 which just earlier today started running rough and was down on power. I have been driving for 50 years and do most of my own maintenance, so I immediately thought it was down a cylinder. When I got it home, I left it running and disconnected the coil packs one at a time. Number 2 was the only one that didn't affect the idle, so that gave me a clue. I pulled and cleaned the #2 plug (it wasn't bad at all, and the plugs are fairly new). No change. I then hooked up my code reader and it also says #2 misfire. Sorry for the long intro, my question is, what are the chances a new coil pack would fix the problem? There's only one shop within 50 miles that will touch a Mini, and they're ridiculously expensive. THANKS!
I am experiencing an engine misfire in my 2013 Mini Cooper S and we have changed the coil, plugs, and sensor, the only thing I have not done is the fuel filter. The mechanic advised that an electrician should check and he came up with another story of a faulty brain box. I have not enjoyed this car even for a whole day. The problem started days after purchasing it. it started with a slow movement they claimed it was a result of a lack of turbo not charging, later it started shredding fan belts and up to 8 belts were damaged. Now the belt issue is rectified but the misfiring still persists. I need some advice is there any chance that the misfiring problem can be associated with the brainbox problem please help me.
Hi, thank you for the work you do. I have a specific problem... most times when I start my 2011 mini, the idling is rough and sometimes produces smoke from the exhaust but when I disconnect any of the Camshaft sensors(then reconnect it), the idling becomes smooth again. Please help
My 2012 Mini Countryman is now is the show, I added oil because it was extremely low and then instantly the rough idle and check engine with multi cylinder misfire codes. checked the head gasket and antifreeze is high and clean. Changed out the sparkplugs and coils and still rough idle and check engoine light. Having the garage check the fuel pump today. Any other thoughts???
Salut, j’ai une Mini Cooper S 2013 R56, le message de perte de puissance est apparu sur mon auto alors j’ai changé les pièces graduellement pour trouver le problème par rapport au texte ou vidéo je voyais sur le net. J’ai un code misfire multiple P0300, misfire sur le cylindre 1 P0301, misfire cylindre 2 P0302 et misfire sur le 4 P0304. Mais les misfire sur cylindre 2 et 4 ne sont pas actif présentement. Même que dans le compteur c’est juste le 1 qui en produit. Premièrement j’ai commencer avec les bougies, deuxièmement le filtreur à gaz, troisièmement le coils Pack, quatrièmement la pompe haute pression, toujours la même chose. J’ai essayer de changer un camshaft sensor et toujours rien. Je m’enligne pour démancher les injecteurs, j’en ai commander des neufs. Je commence à douter du ECM, je vais aller vérifier aussi pour les durites. Je commence à être désespéré, avez vous un autre piste que je n’aurais pas parcouru ? Merci !
Hi, well expained video! I have acceleration lag/hesitation in first and second gears on my mini one (R56). Any thoughts? Any advice would be greatly appreciated thanks.
@@CraftyWorkshopBuilds, thx so much for the reply. They haven't been changed for a couple of years tbh. I haven't got a fault checker and I haven't got the triangle warning or engine light on the screen. Will mine have a boost leak with it being the lesser brake horse power? Thx again for your interest.
I have a 2012 R56 JCW with N14. 3 days ago, upon cold start, it sputtered and struggled and died within 5 seconds. Then again, but didn’t die, and cleaned up after 10 seconds and seems fine. Same thing again next morning but threw codes this time, misfire cylinder 1 & 3. Then next morn, same thing but code was for cylinder 2 & 4. It’s very odd because once it cleans up after a few seconds, it runs perfectly fine until it gets cold sitting overnight. Any ideas?
Got a mis-fire on low revs on Mini Cooper r56 but disappears once over 40 mph any ideas ? Car not overheating at all no smoke but a rich fuel smell HELP 😳
Just had my 2009 Mini S head rebuilt and car is running. Cleared all engine codes and was driving to get ready for smog test. Felt rough idle and move cylinder 3 wiring and I felt suddenly got better. Drove fine after that but the CEL came on while on freeway. Cleared code and everything ok again. I might have loose wiring at coil pack connection. Not sure how to check. Any recommendations?
Hi sir. i have a 2009 r56 cooper. i had a cel light on while driving on the freeway. i changed the plugs and the coils due to rough idling. switched the coil packs and found that cylinder #2 is still having a misfire. p0302. could it be the fuel injector? you said cracked valve does not throw a cel. i hope it is not a low compression problem. thanks in advance
Hello, I have a 2010 Cooper S Clubman and currently in the process of changing out all spark plugs and 2/4 coils. After doing a diagnostic I got a P2195 code; On top of a P0300, 0301, 0303. The one code I have a main question is P000A code which says Camshaft Position Slow Response Bank 1. Is this something major I need to get checked at a garage or will this issue resolve itself when I complete the plug and coil replacement. Thanks for the videos, I have learned alot from watching your channel.
I had the same issue on my 2013 S model. I replace the valve timing solenoid and it took care of the problem. Paid $25 bucks for the solenoid through Amazon.
I'm having problems where my mini randomly stops while driving so it shows the amber check engine light symbol where you read the RPMs and then the car stall's and loses power and then it completely stops and you have to wait a few minutes before it will start again and this has been happening frequently, Do you have any idea on how to fix this problem? It's a 2011 mini Cooper clubman s with the N18 engine.
My mini has had random misfires in cyl 2,3,4 and I’ve already replaced spark plugs, tested coil packs, prev owner replaced hpfp, I cleaned the intake valves, and yet it stills misfires. My car has feels super sluggish and when I floor it inside the cabin starts smelling like fresh gas. I’m thinking maybe there’s a fuel line in the bay that’s cracked or an injector leaking or clogged.
sounds like my 2010 I'm having a misfire multiple cylinders. I've replaced the coil packs, plugs, hpfp, fuel filter. Mine runs great though it's only cold starts that give it the code. Have you checked your fuel filter? That thing is a bitch to get on and off. If the previous owner replaced that with the fuel pump like I did maybe he didn't get it to seal correctly and you're losing pressure and getting that smell. easy enough to inspect. You should be able to see the hpfp leaking pretty easily.
Misfire on cylinder 2 & 3 on my R56. Cylinder 3 ignition coil wasn’t snug to the spark plug and cylinder 2 had a bad spark plug. Misfire caused engine light, rough idle, lack of power, and a slight knock. I ended replacing all four spark plugs and ignition coils. Runs a lot smoother and reactive with no engine light. Still has a vibrating idle. I’m assuming fuel injectors and exhaust manifold need cleaning. HELP! I also have an R55. It runs very smooth but the spark plug tips has oil on it. I was thinking it was a valve cover seal leak. Any suggestions?
How’s it going, got a 2009 Mini Cooper s turbo. Recently I’ve been having idle problems when I’m at a stop. It idles then drops, on my voltage it goes from 14.0 to 13.5 then jumps back up. After I park I have some backfire in the exhaust, but no check engine light. Any suggestions?
Sir i need your help, i have 2009 Mini Cooper when i drive it for an hour cylinder 3 stopped working engine idling roughly even when I swapped the coil, plugs and injectors, what can that be please
Having a random misfire code across all cylinders, car shows no noticeable misfire or faulty idle. Spark plugs, coil packs, fuel filter, valves, guides, timing chain, valve seats, vanos all replaced, car runs and idles perfectly.....and still throws random misfire codes on all cylinders.
Hello! I have a R60 2013(countryman). The issue with the car is a misfire on cylinder 3, I replace the coil but I still have the same code ( I use Creador C501 to read my codes) I was about to replace the spark plugs but before I decided to fill up the tank then I run the car and the problem get worse, when I checked the codes again I get back fire in all the cylinders but #4. I believe something is clogged. Any video about how to replace the fuel filter on the tank and the pump too?
So I have a 2009 mini Cooper s turbo i was driving car it seemed fine I did have a check engine light on but code was only for thermostat not opening at set temperature and a certain time . Car had no misfires at first but then I started driving on the free way decided to give it a little more throttle and car rpm’s dropped reving down then check engine began to flash bogging out . I then pulled over checked codes giving me random misfires . I cleared codes then cycled key again to get proper codes giving me misfire on cylinder 2&4 I removed spark plug and plug was burnt . I replaced spark plugs and both coils for cylinder 2&4 . Cleared codes and error still persisted . Fault was for the same cylinder still I then removed plugs again and cylinder 2&4 were dampen with fuel . I began to test injectors with scanner each operating normal . I haven’t tested for compression but if someone has some tips on this that would be great . There’s nothing on RU-vid
So I just got this Mini Cooper and I’m driving on highway then it starts hesitating on moving with rpm’s up/down. The check engine light came on. I got to my destination, shut off an turned right on and engine light gone but rpm’s are still lagging. What’s a good starting point. History says engine serviced back in 2016
How do you diagnose a problem with the injector? If it is clogged can it be cleaned? I already put new plugs and coil packs all the way around less than a year and 10K miles.
My 2010 R56 N14 Cooper S Turbo has a misfire. #4 cylinder. Compression read #4 at 30 psi. Two others read 125 and one at 170. Maybe, I think, not sure. Except for sure #4. Anyway. Two Shop Owners, both work on BMW's but only one works on Mini's a lot. When first owner mechanic said valve job or replace engine I went to a Mini mechanic for a second opinion Told him what's up and got from him almost same. Except said engines are expensive and maybe not necessary since he has had much success with valve jobs on others with similar traits and milage. ALSO, in his quote he incl. Brakes and rotors and pad sensor. Why? Any clue? Once I hear from you I'll tell you what I've read
I have an u common issue. I have done basically everything and the 1st cylinder is the only one that misfires after 20 minutes when it heats up. And then it's running bad. After an hour it will run well for another 20 min and bad after that. Can anyone help?
hey man! thank you for the video, really like it. got an question: my r56 2013 with N18 engine and 54.000 kilometers on the clock is running rough in stand, in cold condition of the engine the rpm is moving up and down, sometimes falls down to like 500rpm and nearly dies but then moving up rpm again. spark plugs and service is only 1500 kilometers and 2 months old, timing was checken two weeks ago and was great, the workshop said… NO CHECK ENGINE LIGHT and no trouble code. what do you think? I would say maybe its the tensioner, maybe air ratio sensor or even lambda? or maybe its the vanos (variable cam) on one side or on both? high pressure fuel pump I would say is okay so far, because when moving the engine runs fine and has its power. would be nice to hear from you, I can send you videos of the car idling if you want to, maybe we can communicate somewhere else? Greetings from Germany! Cheers! Nico
Hey, shout out to everyone watching from Germany! You said this only happens when the engine is cold, and once it's warmed up it runs smooth? Yea, reach out to me on Instagram for better communication.
when the engine is warmed up its running most time relatively smooth, only moving rpm a little and sometimes runs fine when warm. and the big issue with the rpm falling down and nearly dies only happens when cold. I will message u there! 🤙🏽
Hi man. I have a mini copper s 2011 but I have half check engine and there’s no power in the car ? Can u help I replace the spark plugs and ignition coils it went and came back
When my Cooper S R56 is cold it doesn't idle great as soon as temp is up the idling is normal. And it miss fires when I drive and accelerate or try to overtake. Any suggestions please.
@@CraftyWorkshopBuilds on have had the car for 3 weeks. Started reading parts as I go. Previous owner replace plugs about 6 months ago. Ignition coil pack looks horrific 🙊🙈🙉
I have an intermittent misfire which shakes the engine now and then, I don’t have any engine management light or codes for a misfire though, any idea where I should start looking?
OMG this is my life right now!! I changed out the spark plugs and coils and the P code went away but the Multi Misfire all random cylinders is still there and rough idle, once I give it gas it dies down. It is at the shop and they are at a loss. What was your fix.
Same issue with my R56 My vehicle was running very very rough to the point where the whole car was shaking. Losing power. We scanned the car and got a cylinder 4 misfire. We changed all spark plugs and coil pack and it made no difference. So my mechanic then did a pressure test and one of the cylinders had 60psi. He didn't know what to do after but advised it maybe the piston rings but it will be very expensive and a new engine plus labour is financially pointless. So he advised I maybe better off selling or scrapping the car. This video really helps so I'm gonna go back and show the mechanic. What were the names of all the parts you changed? Great video btw like and subscribed.
Question please.. I’m noticing some white smoke after spraying my turbo with valve&turbo cleaner! I’m going to check for water/oil In my spark plugs. Hoping it’s not a head gasket.. Your thoughts?
@@CraftyWorkshopBuilds Hey Sir! Cylinders are fine.. Top 02 sensors was bad , changed it to the $150. one from Euro..Ugh. Turbo line underneath the turbo has a leak , replaced the turbo feed line.. I would like to meet up with you to have you take a look? I’m finding these cars a pain in the ass.. I have a track 350z ( new race motor built by RT Tuning PA.. might give them this mini soon.
@@trainer008 Oh cool, I'm happy you got it resolved. Yea, the top o2 sensor is a wideband, it is responsible for the air/fuel ratio. If the top sensor is faulty, it will definitely make the car not run good. The faulty sensor probably made the car ran rich, which caused the smoke. The second o2 sensor is not as important. Feel free to reach out to me on Instagram.
@@CraftyWorkshopBuilds thank you! I recently got a missfire and engine code for cylinders 1 & 4 on my 2010 mini Cooper s when driving up a hill and I replaced the spark plugs and ignition coils with OEM products and still have the issue so I'm pretty stumped on what it could be
I have a 2012 Mini Cooper s convertible. I died after 3 days of having it. 2 fuel pumps later it still will not stay running. This is the symbol that appeared before it died
Those damn Mini's are always chasing parts. I've had (2) 2012 vintage S's that gave the stupid "half engine power" light come on. Both were corrected by new coil overs. DON'T buy these from Amazon or eBay. They are knock offs. Bosch brand has been consistent and they're only $20 off RockAuto. I have spares in my glovebox."Just in case". Another thing - it's so GD random - until it's NOT. I clocked my "self healing" N18 at about 45 miles till it happened sequentially. Maybe heat? Maybe a Mini "design feature" ? Whatever.....love em but hate em - I have 5 in driveway, and have owned 11. The NON-S seems more reliable.
