[@waynew5521]

Big help to you.... i actually had engine light on.... and made appointment to drop off car at the dealer just save $500 to $1000 at the dealer because they would just replace with new + labour i couldn't wait so i did scan myself and got 3 code /P0100/P0111/P0113 , then search KZbin and find this video All i did was pull Mass and Map sensor off 2012 135i M sport n55 /e88 motor The Map sensor that connected to the charge pipe had oil on it, Bought a can of MASS AIR FLOW CLEANER from the auto part store And sprayed and cleaned oil off and let dry for 2 min Then re-installed them both .... then start car and within 10 seconds engine light despaired boost was back to normal ....The joy i felt was like no other wooooooow

[@Charkatak]

I was about to clean MAF on my 3rd Gen MINI and your video came up just in time! Thanks!

[@waynebaldycanning]

Just did mine today after watching your video. It worked. Thanks very much from the UK

[@masonlake5004]

I’ve noticed my car hesitating under heavy loads and when ever it would happen I would just let off. Then today I was feeling a little ballsy and I stayed in it. It felt like the car was about to blow up. I finally got the CEL I was waiting for and pulled the code and got p112f. For a faulty maf. Took it out and it looked like I wiped my butt with it. Cleaned it with brake cleaner and she’s running better than she ever has.

[@bonkeydollocks1879]

Brake cleaner is not advised. It leaves a residue on the hot wire and is too aggressive

[@maxim913]

Love your channel, bought a m135i a couple of weeks ago so these video's are super helpfull. Would love more tips and video's on how to keep the car and that lovely n55 engine healthy.

[@KiesMotorsports]

Great, thanks! Great car! Sure, I'll see what I can do..

[@tlbern7710]

Nice. Never thought to clean it, especially being so simple to do. Thanks.

[@KiesMotorsports]

Yep, it's great to do on any car!

[@mzdial]

Hey Bryan.. Just started to run across your videos in the last few weeks. Appreciative what you're doing!

[@KiesMotorsports]

Awesome, thanks!

[@dougjamesvandals]

Thanks older x3 w 141k on it ..changing oil n air filter...very dirty . Will clean MAS thanks

[@ravewanderer]

Any opinions about when to actually replace the MAF sensor? Every 10 years or anything like that? Thanks in advance ☺

[@alexvaldana]

Bryan, if the MAF sensor has problems/it's dirty, it should prompt an error on the iDrive or some other CEL error? I ask you because I have some hesitation on my B48 F30 LCI when accelerating from 1.1K rpms and don't know if I should focus on cleaning the MAF sensor. Thanks for the reply

[@christesseris1458]

I have a similar symptom at 1.1K rpm. Curios if you ever figured it out and fixed it?

[@nonievillamoremoragriega4605]

Can i use electronics cleaner there's no available maf cleaner in the area

[@DerHalbeEuro]

If i have that orange motor symbol in the cockpit do i need to replace the sensor with a clompletly new one or is it enough to just clean the old one?

[@JHall]

LIke the addition of the background music!

[@KiesMotorsports]

Thanks! You'll have to teach me how to vlogg one day, ha.

hahaha just keep watching other people's and keep doing what your doing!

Buddy, while doing this job I lost one screw while removing one of the two screws of MAF sensor that fell into the engine compartment and was not recovered. Any way I can buy the screw ? Part no?

[@abdulbeany1894]

Hi can i clean the maf after i driven the car or does engine have to be cold thanks

[@omarosman6180]

A very helpful video... thank you ...

[@keithbillings3649]

I am having exhaust chugging on coasting and braking, so I did this and it was super easy. It didn’t fix my problem though, so I suspect that it might be a partially clogged exhaust. It’s just really weird how it does chug on idle or accelerate.

[@connorbassstudent9108]

Have you found a solution to your problem? Mine has been doing the same

[@tylertyler965]

what kind of screw driver it is? i really need one for tiny space!

[@TEAMCREAM_96]

The spot you were really focused on was the iat sensor

[@michaelnikprelaj6679]

Can I clean the MAP sensor too?

[@jacobpowers8958]

Probably a stupid question but is it fine to clean the sensor on a 18 330i?

[@zaferdortdogan5564]

Hi Bryan, Is it really effective

[@stashbob]

Brian, So, check engine light came on, I threw a code of P00BD. Had them clear the code, came home and cleaned the sensor just like your video...THANKS. A couple of days later, the check engine light came back on. This time I cleaned both the MAF and the MAP on the charge pipe. If this worked, should the check engine light turn off without being cleared? Any help would be greatly appreciated!!!

[@pvherr]

Hi Brian, I have to admit I was skeptical about this video, but it really solved my problem. Thank you for posting this video.

thatdronekid torreto his fuel economy was bad most likely

[@MohamedElmosaly]

@@latinwords2367 Hi, just came across your comment. My engine shakes every time I start the car and now I got a yellow check engine light. The error code is related to the MAF. Did you clean it and did that fix your problem?

[@infiniteuniverse1757]

Just did this, appreciate the vids. I had to watch again

[@xZen0sx]

Hey Bryan, thanks for the informative video again. I was wondering if this is sufficient enough or do I need to clean throttle body too? Saw they sell CRC product in bundle so I wanted to know. Thank you

[@KiesMotorsports]

Hi, thanks! If you look on the CRC throttle body cleaner, it says not to use it on Turbocharged cars, so I wouldn't use that

[@sanchitnigania1]

Any online link for buying these? I have a 2013 f30 320d there is an engine light with maf error. The car runs fine and no problem with the idle and power. My mechanic checked the wiring plus cleaned the sensor a couple of times but the problem still persist. Thanks in advance love from India :)

[@simonel9332]

Do you need to disconnect the battery?

[@CaptainCarling]

Hi Bryan, I have a 2014 M4, and just recently when I start it up from cold and try to pull off, it starts to splutter and then cuts out (not all the time though) The car has done 41000 miles. It runs fine after the initial start up failure, so I was wondering if dirty maf sensors could be the problem....what do you think?

[@wavybaker7074]

Have you figured this out ?? I’m having this problem now

[@nh3388]

[@kvrh]

check for any vacuum leak. clean maf and throttle body, check your air filter and clean it. if still occur, check your fuel filter and pump.

[@mikeyroodbol3121]

[@robertdennison2517]

I want to do the same thing to the MAF on my 335i soon. Do you wipe any excess spray off or do you just let it completely dry?

[@KiesMotorsports]

No, it dries in about 3 seconds, super quick!

[@robertdennison2517]

could a rough idle be caused by a dirty MAF?

[@KiesMotorsports]

Yes, it could be a factor

Can i use break cleaner? I bought a 2005 530i. Popping up codes p16a7 We cleaned maf sensor with break cleaner After that, Car still runs very rough. Very little power and sputters. Cant accelerate fast at all.

You destroyed it with brake cleaner

[@Scotford_Maconochie]

Hey pal i cleaned the valve intake on my '13 E70 X5 with CRC GDI IVD valve intake and turbo cleaner and after waiting an hour as per the instructions and taking it for a spin on the highway i got a huge grey cloud of smoke and a check engine light! any idea if its the MAF sensor since some of the stuff might have come into contact with it! Gonna try the CRC maf sensor cleaner now i think

[@gilgonzalez5902]

The smoke coming from the tailpipe is normal its all the carbon that was being broken down which is a good thing! Clear codes and you will be back in business running better than ever. Just did the same thing on my N55 a lot with a new charge pipe and BMS intake.

[@SmerkeHD]

Is it essential to use mass air flow cleaner - will brake cleaner suffice?

[@DrCeramicDallas]

Too rough.

[@ChrisDan94_]

I’ve taken my car to BMW and several shops and get a different answer each time. When I’m at a stop light, foot on the brake my RPM is revving up and down like crazy. Threw some fuel system/injector cleaner from Walmart into it during my last fill up and it didn’t do it for a week. Then during my next fill up it started doing it again. Every answer I’ve gotten was the following! 1) Fuel injectors 2) Carbon air filter 3) spark plugs 4) brake flush Each shop gave a different answer. It’s an 08’ 328i automatic. 102K miles.

[@drone1028]

Did you fix the problem? Sounds like spark plug gap to big, or vanos need cleaning.

[@Cridkid1977]

Could be your ignition coils? I have a 2012 and when I changed my spark plugs, I also need to replace the ignition coils as well. My RPMs were doing the same thing. BMWs are awesome when everything is working properly LOL Good luck!

[@harshilpatel6992]

I did this on my 435i and man, I feel like I bought a brand new car!! Drives like 0 miles on it.

[@DB0310]

I assume its similar for the 328?

[@KiesMotorsports]

Yes, same basic process for every car

[@ahounda]

Hi Brian, do you need to disconnect the battery before removing MAF

[@Sahildrift]

No just take of the electrical tab clip

[@VictorEstrada]

Hate to be the one asking this but, what's the purpose of that, and does it actually make any noticeable difference?

[@KiesMotorsports]

You'll gain about 35 horsepower ;) Just kidding. Yes, you can notice a smoother idle. My car had a lot of oil in the intercooler, which coated the sensor in oil. It messes up the signal, so your car doesn't know exactly how much fuel it needs to add to compensate for the air flow

[@NilanWeerasekera]

how can oil get into the intercooler?

(mute point by now, but incase anyone else were to read comments) I use one in my e46. Don't over oil them, that is the mistake people do, as too much oil could then affect or damage the MAF.

I had a hard time removing the power connector of the sensor so i threw a towel over the engine bay and cleaned the maf sensor there and let it dry in the sun for 30 mins

Sebastien Rosil yes. I ran a car without a MAF, and the throttle response didn’t work after 1.5k RPM if I remember correctly
