Best video ever on MAF sensor and air deflector not only taking your time while explaining details not to mention the process removing and replacing the MAF is much better and different from several other videos I have watched IMHO. Thanks... And no one ever mentioned the pink dot LOL.

[@GarageDynamics]

Thanks PhoenixStarman! I'm glad you noticed the pink dot!! It's still there too lol!!!

[@kevinkelker4371]

Just wanted to say thank you. I was starting to experience a slight rough idle from time to time. Engage trouble shooting mode. Of course I came to your channel first. I first tried the MAF spray, and that did help, but didn't solve my problem. Step two was changing all the spark plugs as well as a new MAF sensor. I also added Liqui Moly Jectron fuel injection cleaner. That solved all my problems. Just needed to express my many thanks for your videos.

[@GarageDynamics]

Hello Kevin Kelker! Wow! That's awesome! I'm glad you solved the issue and you're car is running smooth again! 🙌 It's always a pleasure to be of service to you :)

[@olatundeabiri7048]

Clean clear voice over. Nice video on this. Thanks for sharing

[@davidmortensen3915]

Great video! I had to remove the MAF sensor to change out the 5-way vacuum fitting just in front of the MAF housing. Viewers might want to replace this and the breather hoses hoses while the MAF sensor is out.

[@pasorie8490]

You’re awesome 👏. You help me save a lot of money. You can’t believe this, a vehicle mechanic asked me to pay him $375.00 part and labor to replaced the MAF sensor. After watching this video, I fixed the MAF and car my run smoothly. All I did was cleaning. 👍🏿👍🏿👍🏿👍🏿🙏🙏🙏🙏Thank you

[@PhoenixStarman]

And that is cheap.

[@lapdogg]

Yeah $375 is super cheap.. get back to me when they try charging you $5k for a job that costs $300 in parts that you can easily do yourself. Lol.

[@nv1493]

Nice work. You can also spray the sensor in place. I would suggest pulling the TB as well, a bit more work but you'll do a better job of cleaning plus be able to install a new base gasket. Also, if theres oil in the hose to the elbow that's indicative of a failing pcv separator. Replace the pcv separator assembly. You don't want oil coking inside the TB or inside the intake on the runner flaps.

[@penng7020]

You make GREAT Instructional videos!!!! Please keep doing them for S500.

[@mateshaljc]

Outstanding video instruction. I was unsure about doing this until I saw your video. Thank you. DONE!

[@GarageDynamics]

Thanks for the kind words Mateshaljc!! I'm glad this video was able to help you out :)

[@wilborth5th]

Just by the begging of the video I’m already your fan mister thank you so much for such a super great video wowww

[@GarageDynamics]

Thank you for the kind words Willy Will!!

[@joseph4321a]

Awesome video, looked at 20 before finding yours, most helpful and precise! got the job done car runs GREAT again!! Thank You!!!!!!!!!!!

[@GarageDynamics]

Thank you Joe Giordano! I'm glad to hear your car is running great now! :)

[@vinmega1074]

Thank you for these videos. I have a 2005 S430 that runs perfect and your videos have been really helpful in maintaining my Mafia Prince Mobile

[@GarageDynamics]

You're welcome Vin Mega! I'm glad to hear the Prince is running strong!

[@ayppen396454]

Thank you. Helped me on my wife's ML500 W164. Same procedure.

[@GarageDynamics]

Hi +ayppen396454 Nice! I'm glad everything worked out for you.

[@marshallw.6343]

Great video... I love how you are detailed in your explanations.

[@GarageDynamics]

Thank you Marshall W.! :)

[@hitzoneproductions7858]

You're amazing at explaining things. Thank you so much.

[@GarageDynamics]

Thank you for the kind words HITZONE PRODUCTIONS. You're very welcome! I'm glad I could help. Cheers! :)

[@melaleuca727]

You can just as easily remove the MAF upper part# 280 217 810 by itself. Toss away the bracket. It's not needed and has been discontinued.

[@setidepp4853]

Thanks! Great, detailed explanation. Did mine today and it was a total success! Subscribed.

[@GarageDynamics]

Hello Seti Depp! Thank you for your support of the channel! I'm so glad to hear everything went well! Many blessings to you brother!

[@richardb434]

Really beautifully made video. Thank you so much!

[@GarageDynamics]

Thank you for the kind words Richard B!

[@toscaninimark7683]

Great. Works like magic.

[@revinot]

I assume if you just need to clean the MAF sensor you can just remove it and not the whole assembly to get to the throttle body? I mean just unclip the MAF from the electrical connector and bottom bracket leading to the throttle body?

[@AlanTrades]

Nice detailed video, but couldn't you just unscre the two bolts on the sensor and pull it out?

[@hussam384]

Impressive video

[@GarageDynamics]

Thank you Hussam!

[@moonyachti]

I wouldn't recommend pushing open the throttle it is very sensitive but the best method is to grab ahold of long enough stick that can fit from the seat of your car to push the pedal down to get a better cleaning of the throttle or if you have someone to do so would work best lol 👊😷👍

[@SavedbyHim]

Good video but I must say the v8 cars are a walk in the park compared to the V6 m112 engines. There is so little space to work with.

[@HarlemhitPrudholme]

Will cleaning the mass air flow make you car acceleration better or should i just change the throttle body have issues acceleration

[@paulrob2375]

Can I spray the sensor without removing..seems easier..thanks

[@GarageDynamics]

Hi Efe Evue, Yes you can. I would recommend to wait 10-15 minutes before turning on and starting the car just to make sure any traces of liquid residue has evaporated first.

[@TheWhites.1121]

Hope to get this done soon on my S500

[@GarageDynamics]

Hi +cheytown03, The sooner the better :)

[@davidwright6902]

SkipArtPictures I have 2010 merc gl450, I live in St Kitts I have to fly in engineer from Puero RICO, done it twice after he goes I'm left with another problem, racing radiator fan is the latest, as you have been asked before would I be ok to clean without removing please

[@nick2128]

Can I remove the engine cover and spray the sensor? Also have you used seafoam? I was thinking about buying some and pouring it in the gas tank whenever I need to fill up again

[@GarageDynamics]

Hello Nick, Yes, if you're in a hurry you can just remove the engine cover and spray some MAF or Electronics parts cleaner on the sensor. Regarding Seafoam, I have never used Seafoam on a mercedes engine. I have used BG44K Platinum right before I started a 2,500 mile road trip in the Mercedes S500 and it ran great! For BG44k you just need to apply it to the fuel tank. One bottle treats a full tank. Hope this helps. Cheers!

[@HarlemhitPrudholme]

Is this the caused of bad acceleration or throttle body

[@jackr7550]

I am literally stuck on step one, unplugging that terminal is excruciatingly hard. It has not budged no matter what I do. W203 C55

[@robert696967]

great vidio. "thurough" . left no details out. thank you.

[@GarageDynamics]

Thank you Robert Angeleri!! I'm glad to hear that :)

[@user-xl4zy9ki6r]

Man my gas pedal is not accelerating and I just got a new battery so it says charge it everytime I try to go in gear

[@garyzhang5099]

I find my connector is really hard to remove, I'm a bit scare to wiggle it. Can't disconnect it... Are there any tip? is it really that hard to remove?

[@xelnation]

How often should I do this? How do I when I should clean it.

[@GarageDynamics]

Hello Alexie Diaz! I recommend cleaning the MAF sensor every 10,000 miles and also when you change the air filters. Another way to tell if it's time to clean the MAF sensor is when the engine shakes a bit more than usual at idle. Keep in mind though that engine shake can be for a number of reasons, but sometimes cleaning the MAF sensor helps. Cheers!

[@ojack1000]

Can someone please provide the part number for the breather hose shown in the video with the pink arrows that connects to the MAS body?

[@vr-cx6lq]

i was under the impression that its bad to touch the throttle body plate i want to clean mine but dont want to damage it 2003 c240 please clarify

[@GarageDynamics]

Hello V R, Not to my knowledge. I would double check with the people over at mbworld.org/forums/ I've cleaned my throttle body and plate many times and the car only runs better :) I hope this helps. Cheers!

[@vr-cx6lq]

@@GarageDynamics i was under the impression that electronic throttle bodys can be damaged if you push in the plate for cleaning thats why they are best removed trust me i dont want to go through all that if i can press the plate and not break it i was delighted when i saw you do it that way i just wanted to double check

[@MrEdtheraiderfan]

Why can't you just take the top part off and clean or replace the maf?

[@GarageDynamics]

Hello EdtheRaiderfan Cunningham, The top part of the MAF has a metal screen that is built into the MAF. It's also there to protect against damage to the MAF sensor. It is very delicate and just touching it with too much pressure can possibly damage it. I hope this helps. Cheers!

[@MrEdtheraiderfan]

@GarageDynamics thank you for the response. I went ahead and changed the whole unit as suggested along with my fuel pump and filter along with my crankshaft position sensor. Car kept shutting off while driving. It seems fine now, but it's only been a couple of days. 🙏🙏🙏

[@GarageDynamics]

@@MrEdtheraiderfan You're welcome! That's awesome! Yeah, for some reason I know with the S500, at 150k the crankshaft position sensor goes out and the car will shut off at idle, or fuel cut while driving, giving it the feeling like you are stepping on the brakes while driving. I hope all is well now and you get lots of good fun mileage out of your Mercedes 🙏🙏🙏

[@MrEdtheraiderfan]

Hello sir. Just wanted to update you on my 2006 S500. It seems that all the work I had done didn't stop my problems with the car stalling. I really don't know what to do now. The vehicle doesn't act up nearly as much as before, but it will cut off still while idling. Two days ago, the car cut off while driving on the freeway. If you have any additional advice, I'd appreciate it. Have a good one bro...

[@alexandrequach7865]

Merci beaucoup your video so helpfull in France we dont this ...... thanks

[@GarageDynamics]

Thank you Alexandre Quach! You are very welcome! I wish my French was better lol! Cheers!

[@SuperBetonico]

Can you help me..? I bought a MB 190 E 2.3 16 from Spain and brought it top Mexico City, the problem is alttitude, therefpre the car is not idling proper, from sea level to 8000 feet above sea level, the old opwner tells me to find this little like clock to settle the new alttitude but i can´t find it, not where the batterie is neither around the headlights, where he told me too.. please.. HELP¡¡¡¡

[@GarageDynamics]

Hello Alberto Calderon, I'm sorry to hear you're having difficulties with your car. I'm not familiar with the 190 E 2.3 16. I recommend you visit mbworld.org/ Everyone on that forum is very knowledgeable and can help you fix your car.

[@jonathantucker2319]

So if the mass sensor isn't the problem will it be throttle body that will need to be changed?

[@vasilenegrea8820]

Hi guys i have a cl55 amg super charger 2003 can't find were is the air intake injection sensor ? Any one knows thanks guys.

[@Furious_Mage]

Can you clean the throttle body with brake cleaners?

[@GarageDynamics]

Hello Reverse Light, Please do not use brake cleaner. I would recommend using throttle body cleaner or MAF cleaner. I hope this helps. Cheers!

[@Furious_Mage]

@@GarageDynamics thank you so much

[@GarageDynamics]

@@Furious_Mage You're welcome :)

[@muhammadardeanda1322]

Is this working for w124 e320 m104 engine ?

[@ICEFOOL]

hey, the mass air flow sensor bracket on my 02 c240 mercedes is broke and i've looked everywhere on the internet for a new or atleast a used one and can't find nothing. do you have any ideas where i could get one?

[@doomer_john]

ICEFOOL junk yard maybe?

[@melaleuca727]

You don't need it. It's been discontinued.

[@PhoenixStarman]

$5 everywhere NEW

[@cibarra3905]

I have a 06 R350 with a MAF sensor check engine light on , can someone help me out , Thanks

[@Jasshands1]

Busted the clamp, do you know where I can order a new one.

[@melaleuca727]

You don't need the clamp. (Bracket 112-141-04-40) It's been discontinued.

[@undisputedretail]

Is this hard???

[@princesalopez9550]

can i spray clean ir without removong it

[@GarageDynamics]

+iris lopez Hi! Yes, You can spray your MAF sensor while its still connected to the throttle body (assuming you have removed your air box). I would just recommend that you hold off on starting the car for at least 10 minutes. That will give the cleaner a chance to evaporate, so that it doesn't get pulled into your engine.

[@princesalopez9550]

+SkipArtPictures. thanks;)

[@GarageDynamics]

Anytime Iris!

[@HarlemhitPrudholme]

Will this help my cLk Mercedes acceleration better

[@bnoakes4899]

Uh, unplug the MAF?

[@OMGWTFLOLSMH]

Spraying silicone around a MAF sensor is not a good idea. Spray some on your finger and wipe it on the areas required.

[@joseh9031]

Wish u showed where its actually located lol

[@joseh9031]

Also wish we were told about the throttle body and a bit more expansion on that

[@jmenge4253]

If it works...don`t touch it

[@Khoolhwhip]

Let me tell you this process on the clk 500 is soo damn fucked, 😭😭😭
