Rough Idle, Vibrating & Shaking Idle Problem BMW 5 Series 3 Series E90 E39 528I 328I M5 M3

[@BeamerFanaticsE39E90]

The cause of all this problem was an air leak. That was very small. I found the air leak by doing an engine smoke test that you can find on my other videos. another thing that helped me solve the problem was replacing my serpentine belt and belt tensioner.

[@omarlopez4503]

I had this happen to my 5 series but not as bad. I recommend doing a tune up. It turns out its due to coils starting to misfire. If i am wrong, i do apologize i am not an expert but that is how i fixed mine. Plus a tune up is a good way to start. Mine would do rough idling at times and my check engine light came on.

[@cs3943]

Check your ground straps and maybe get a smoke test to see if you have any air intake leaks. For misfires pull a few coils and see if there is any oil on your plugs but car is pretty new unless you drive hard or someone did some work and didn't re-install a ground straps. Check the PVC Vacuum. Better get some tools or you'll be broke. B.M.W. (Bring Me Work) Lemme know what it was boss.

[@ryans413]

Yes but you need the sensor plugged in you can't drive around without it. The computer won't know how much air to fuel ratio it needs to run the engine properly. The cause of the RMPs going wacky is probably a dirty sensor try cleaning it.

[@simplelangperorock]

check the intake/exhaust connection on the vanos solenoids. make sure they’re connected correctly. i mean, exhaust vs intake.

If you have a bmw car which has misfiring codes or rough idle, and you have changed the plugs and coils or even injectors but the misfiring codes still there and rough idle still persist - just do this. 1. Change your eccentric sensor with a new one, your misfire codes and rough idle will go away for good. *Remember just change/ replace your Eccentric Sensor*

Learn how to change your own spark plugs, coils, oil. You will save a ton of money . Don’t get overwhelmed by the easy but tedious work. Also try buying your parts at one store so you get warranty(sparks , sensors, coils)

[@aaroncortez7828]

Careful some codes it throws out arent trully what they entend to be. sorry for the fact you spent so much money however the air flow sensor could have possibly been a huge factor. but i know the true problem to the misfires in separate cylinders. it leads to alot of different codes an people pay so much money to fix it and find out it didn't solve the problem. i own a 328i sedan 2011. i had rough idle an shuttering. i tried so many things. i replaced camshaft sensor, solenoids, took it to a friend who had an amazing computer and still it through off so many different codes that had no reason to be there. so i decided one last try or thats it i was gonna trade it in. it happened to be the coils an spark plugs. but before i replaced them it got so bad my car shuttered constantly from 2nd to 3rd gear i would lose power and had no response to throttle. or sometimes the car would die in the middle of the highway. after replacement of the coils and spark plugs, it had another issue with the A/C compressor. Diagnosis on the A/C compressor is loud squeals from the engine that are embarrassing and doesn't go away until car is turned off, as well as weird fluctuating A/C. (This can also cause some shuttering). I replaced that and also reset transmission ,due to late gear shifts, by holding down the gas pedal for 40 sec while the key is in and engine off. then drive 20mph for a mile. (this takes away the late shifting in automatic). Also if you have some extra cash throw some injector cleaner in your car. My car now operates like a champ and has great gas mileage! all of this was 25,000 miles ago. HOPEFULLY YOUR NOT USING UNLEADED! If you want the best out of your BMW give it the best. (Key factor - driving in M/S mode try not to redline) or better yet dont redline even though critics an technicians say you can. It puts alot of stress on the engine and causes things like this to happen. I know by first hand how fun it is to push these cars to their limit but its not so much fun when your wallet is crying.

Your timings out you need to get it lined back up with a special tool because your maf is confused from the air supply from the valves do the chain its common for misfire and rough idle

[@segoiii]

+conversejordan german cars are good at "felt quality". The inner quality feels good and from the point of driving, they feel good, too. And they are good when you want to show off. But from technical side, they are very faulty. Especially the last ~ 10 years, they became more and more faulty. Volkwagen and BMW i.e. have problems with timing chains, piston slaps (knocking sounds), many electrical faults, breaking ignicion coils and many small problems like this with the air leaks. Almost every Polo that is older than 8 years, has it. If you want to have a reliable car, dont buy a german car ! Buy Toyota! If you want to show off, buy a german car and save money (or learn) to repair it :)

Does it shake when you drive? You need to clean your both Venos selanoids if it happens again replace both exhust and intake of your Venos.

The other thing is use premium fuel only. (95 or 98 octane fuel). Check your spark plugs and your coil seals if it needs replacing.

[@MyChannel10198]

Btw you can do all this by yourself and save some money

[@annetterodriguez3942]

My Channel my car needs a new catalytic converter. could that be a reason it shakes/ vibrates or could it be something else

[@yogame3456]

Annette Rodriguez your needing a catalytic because your oxigen sensors are bad. before you spend time and money on another cats take the front oxigen sensors and check them if the small holes are clogged with carbon it won't read correct and it sends a bad reading to the DME ( ECU or engine computer ) and usually it tricks the computer to throw codes with system too lean or too high meaning it had to adjust the amount of gasoline pushed to your injectors because the amount of air was higher or lower than what should be. if it push more gasoline it won't get burnt complete and some goes directly to the cats . also you can see it by smelling a spark plug tip , oddor is hard and sometimes looks wet or dark . different from oil . or unplug the engine oil refill cap and smell it . when it smell as gasoline instead of oil that's your issue. you can try cleaning the o2 sensors with some brush and air pressure if it doesn't work just get some news. even if you put new cats and don't change your o2 sensors you will get the same issue in the future . also if there is any oil leak or vacuum leak it will make your car kill the o2 sensors and then your cats. bmw engines are made to be almost sealed from air that's why they have a vacuum pump .

Already cleaned a vanos solenoid (not sensor) and still same problem after a week. Sooo I found a pack of coils for $100 and trying that with new plugs cause they go out eventually, recommended anyways when you do a tune up.

This was happening to my BMW - in most cases its one of those sensors that is causing that issue.. - I changed the vanos and idle control sensors - new spark plugs and I also replaced the fuel injector for cylinder 6 - problem solved. Always test for vacuum leaks, if you do not have a smoke machine to do a smoke test----- - one quick way to test for a vacuum leak is to do this - start the car, while the car this idling rough, remove the engine oil cap for the engine, if the rough idle goes away, they you have a vacuum leak. Put the oil cap back on top of the engine and if the rough idle returns then you know you need to change the ---> rocker cover gasket. My friend and own a shop that fixes only BMW's.

Hi, I have had a number of BMW´s and MB's. I have had many air leak dependent faults. BMWs often have air leaks in rubber intake parts, and MB´s often have cracked vacuum hoses. I always start my investigations by scrutinizing the parts above, which are the cheapest to repair. I have seen many times that people swap expensive parts such as MAF-sensors, other expensive parts then eventually giving up and sell the parts after draining the bank account. So list possible fault reasons, and start with the cheapest fix first. Good luck.

[@chelsiefetherman3324]

Start with changing spark plugs and ignition coils. Next clean VANOS solenoids-since it’s not throwing codes they don’t need to be replaced yet. If that doesn’t work, clean your MAF sensor. If they’re is a misfire in cylinder 4 then I would go with a spark plug and ignition coil. They probably need to be done anyway. Needing an oil change won’t do this like you said, just so you know. Also, you have a bulb out lol Some of the advice people are giving in the comments are ridiculous or an issue that happens 5% of the time. Like the timing chain issue and differential plate pressure someone recommended. You can’t solve this problem just by watching a video and issues like those would be more than a rough idle. Be careful on the advice people give online unless they know what they’re talking about and not “KZbin mechanics” Don’t drive with that unplugged 🤦🏼‍♀️ please

[@yogame3456]

Barry Connor I got once a hard misfire even on both cold and hot after the car warmed and that was some kind of cover the coils have that was cracked and it was as an insulator or something to keep the spark hard each time . I guess it was falling all over the place and not going directly to the sparkplug tip . I got some random misfire messages in my 2002 bmw 745i and it stall so hard with no power when driving. it was protecting the cylinder from getting flooded of gasoline and harm the engine by bending a valve or something. this cars are are very sensitive and even a small oil leak or vacuum leak ( example. if you don't plug all the way back the engine oil filler dipstick you can get a huge misfire. )

@@elvissamata7526 I read through all the questions and replies. Buried in one of the threads he says it was a vacuum leak. Hope that helps. I will be taking my car in first thing Monday Morning ):

I have the same problem with my BMW 135i m sport package 2009It's been a month now. They changed all 6 sparkplugs, 6 coils, one vanos, the electrical gas pump, the mechanical gas pump, changed the oil, carbon shampooing.... and It cost me 3000$. I have been in and out of the garage for at least five time. It was fine friday when i left the garage, but Saturday morning it starded again. It's always in the morning when the car is cold. The idle is malfunctionning and the car vibrates a whole lot, and the motor light is on.Going back to the garage Monday morning and I am not paying one cent more😤

[@BeamerFanaticsE39E90]

This small air leak that I had cost me $4000

[@jfsmmke]

Did you end up finding the issue ? Mine does the same only when it’s cold out

[@melaniegray9137]

My 5 series 2004 would shake so bad it'd shut off while waiting at a light. Hubby replaced a #2 coil, problem solved.

[@scotty962]

Hey it's throwing a misfire code in my cylinder number four I disconnect the flow sensor it's not shaken going up hills no more.. but I still have a little mis so somewhere I'm 7000km over do on oil change

[@antonmajor8183]

Hey repair fanatic.. where was Ur air leak and how did u find it?

[@alejandroescobar1683]

Hi, I have the same problem, could you tell me where the air leak was?

[@audunjemtland8287]

Thanks for a great video. Could I ask about my car. It got all kinds of variations of start stop problems. (3 shops thought it was the red long battery cable that runs under the car, it was loose in the back) But it wasn't it as they fastened it. It sometimes starts with no problem, then it stops suddenly while driving, it sometimes don't start at all with no ignition sound, and sometimes it tries to 'give' with ignition sound but never 'grabs'. Starts fine without problems Doesn't start, without ignition sound Doesn't start, with ignition sound What could this be?! Thank you for any insight.

Audun Jemtland replace your serpentine belt, Buy it from the dealership.

[@ChrisDan94_]

I just got my state inspection and car serviced (non bmw) and they both said cars in perfect condition I just have a minor rear main seal leak which most bmw owners don't replace... However when I stop at stop lights my rpm jumps and my service light just came on and my car was shaking (I was low on gas), I got my alternator and battery replaced. Not sure what could be wrong. I just got the car checked out last month. They think I am crazy.

[@ericafowler5322]

My BMW 325i is currently doing the same thing except it only does it when idle in reverse. I asked my boss who works on his own cars a lot and he said it might be that the clutch is misfiring with the transmission

[@bobjonjo]

Mine does the same thing too

[@Swizzyj303]

Did you find a solution ?

[@JonesyStayFly]

I've been told on forums don't buy the 7 series. The DEALER told me not to buy the 2002 b/c it was the first 745LI and it had lots of problems. I want one so bad.

[@BeamerFanaticsE39E90]

Yes the 7 series have lots of problems

These cars are only for leasing. Please don't buy a used German car .. You'll really regret it even though they are amazing to drive :,(

[@patricklyana3611]

the car was hesitating or you felt some loss of power?

[@aallexxiiisss]

I did

[@malp6280]

so! in short.. disconnecting the MAS sensor on the intake cleared your issue ie the MAS was faulty.. now have you replaced the sensor to find the start-up good now or is the issue still occurring I've a similar issue with my E46 318i & well the more I'm reading up & watching vids the list is growing shorter & shorter & I'm also starting to aim towards the MAS sensor being faulty/bad.. with the poor running have you found any error codes or not?

[@BeamerFanaticsE39E90]

Mal P unplugging the Mas sensor let me bypass the computer. I replaced it with a new one but did the same thing with the RPMs going up-and-down. This part was never my issue. Problem fixed it was caused by an air leak in my main engine block

[@a.n.o.n.y.m.o.u.s...]

Put a small magnet under your camera bro it’ll fix it but you’ll need to superglue the magnet

[@juliuscaesar756]

Would it give you a engine malfunction and make the car sputter on acceleration before you fixed it

[@crystalpetty6487]

Mine has been pretty rough too.. I'm wondering if it's either the spark plugs or my 02 Censor.. it's not my battery or alternator.. but it starts strong and then it putts out on me and dies when sitting.

[@barc533]

Can the o2 sensor cause rough idle?

[@aimized1460]

@@barc533 try to unplug it and start ur car… yes it can cause rough idle

I have A 2006 BMW 325i & it has been back & forth to the shop for the past 2 months it shakes really had whenever I come to a complete stop & now codes P0597, P1554 & P0012 are popping up what do they mean & what should I do

[@BeamerFanaticsE39E90]

First thing do a smoke test have a shop smoke out the engine to find any air leaks in the engine block.

[@nlaz1675]

Idle control valve or fuel valve

[@ANDYW031084]

Your CCV valve is bad while car is running open the engine oil cap if suks too much vacume replace CCV valve on some models ccv valve is part of a valve cover and on some models under the intake manifold

[@rolandoaqui5808]

Hey Repair fanatic, I wanted to ask you a question Hoses fixed valve cover and gaskets replaced, changed maf sensor coils and spark plugs also bought a new battery. Cleaned out Vanos sensors and still having this issue. Cold start then levels it self out. Do you think my vanos seals need to be replaced?

[@rolandoaqui5808]

I meant to say sensors. This is for a 2008 E70

[@kyvenchan]

I'm currently having the same issue after replacing the valve cover gasket and spark plug gaskets, my air flow rate reading was 1.4g/s or roughly 6kg/h which is way off the 14kg/h baseline. I did charcoal delete and changed air filter. new plugs and everything was buttoned up tight and no leaks found from the smoke test... been getting p00bc code and I tried cleaning the butterfly valve in the intake by sending intake cleaner into where the maf sits, car not happy idling at 600rpm with the low air flow reading... am afraid to take the valve cover off to replace rest of the gaskets

[@frankrivera4479]

thanks for the info I'm having the same problem thanks to you I know what to check first don't worry about the video what your saying is what's important thanks. good luck hope your problem is solved.
