i love it wen you lift the bonnet and you can hear the problem

[@AlexPerez-om4pq]

I had this same exact issue !! Switched the tubing and instantly ran smooth , wish I seen this video before lol

[@themechanic6117]

Gotta love those simple fixes 👍

[@stuzman52]

Nice one Rob and good to see that you had an easy fix for yourself as you needed a break from all the tough ones you've been getting lately :) Have a good one!

[@OneAuto]

Cheers Terry 👍

[@eduardoa4558]

Hello, On my C180k, the Compressor air pressure tube that fits into the throttle valve jumped at 5500 rpm because the clamp broke... :/ Unfortunately it caused damage to some part. Engine fails at cold idle and cold throttle. When it warms up it improves, but it continues to fail when I press the accelerator lightly. There is no loss of power at "full power" acceleration. What's your opinion? What could be damaged when the tube came loose? Tks for help me

[@ast5515]

I'm surprised it even idled. Huge damn hole.

[@SteveRobReviews]

It not always so complicated . Nice one Rob.

[@OneAuto]

Nice to have an easy one now & again. Cheers Steve

[@antoniojavier4693]

Good job .

[@miaji1963]

Daughters mercedes C180 exactly the same symptoms checked sensors few other item could not find the problem was going to order a throttle body but cancelled many thanks for your simple great video

[@OneAuto]

Awesome 😎

[@davdcrstern5043]

What is that valve next to the power steering pump?

[@user-uc7ng8up4f]

ممتاز. شكراً I think this is a very useful video. Thnks.

[@dinorhyseni9838]

I have the same problem, the engine doesn't work well, but I checked the hose well, I know what you can do next, help me

[@125sm3]

Nice one Rob .

[@OneAuto]

Thank you sir

[@mattw612]

Hi can anyone help, I just needed to know where this pipe goes (to and from) as Mercedes are telling me this is the only way they will know what it is any help appreciated thanks !

[@birminghammotorhomeman]

when im driving my W203 starts chugging then stops for few hours and then starts chugging againwhat is the cause would it be feul regulator or feul pump or feul line

[@ricardinhofonzie5949]

Hope you answer me the following question. When you took the MAF Air box out and you released the factory hose clips that are near impossible to get to unless you have an extendable flexible hose clip release tool how in the fuck did you place back the plastic tube in the rubber boot behind near the firewall?

[@felixemefiele-augustine9628]

Pls i need help with my C200k 03, car vibrates so bad on idle with this same sound but immediately i step on the throttle car runs smoothly like nothing is wrong. But when in traffics or idle its vibrates with a dragging sound. Little visible Black smokes from the exhaust on first start in the morning, terrible mileage, most time car wimt accelerate even while engine is running, and most times gear doesnt transit into subsequent gear but only on gear 1. Tunn engine off and start again it accelerates and shifts gear normally. What could be the problem.

[@knottym00se]

Love a quick fix

[@OneAuto]

I wish the repair was as quick as the video 🙂

[@whlawson5812]

On a good running E200k 1.8 litre SC Mercedes put in a plug & display obd2. Voltage for O2 sensor at 0.65V to 0.8V. Throttle valve at about 17.2% open. Air conditioning is switched on. Air intake manifold pressure reading is 0.50atm. Idling 850rpm = piston total displacing volume of 12.75litre/second. MAF at 5.4g/second air flow = 4.9litre of air per second. At ratio of 4.9 : 12.75 the calculated air pressure stucked into cylinder when pistin is at DBC is 0.37 atm or about -0.63barg. This is theortical calculation which exclude the pressure drop across intake valves and the slight extra pressure generated by the vapourised gasoline of 5% to 6% by volume done by the port side fuel injectors. All inclusive there should be about 0.4atm of pressure in cylinder when pistion is at DBC?. Correct? 🤔🤔🤔. OBD2 could not display opening %. of egr. I assumed that EGR valve is close during idling. All the above is like a new learning process for me. There was a e200k owner who after repeating visit to a workshop, plus many parts changed out, only later to find out that his abnormal vibrating engine is just due to vacuum leak at hose for PCV. Regards to all.

[@robertczm]

I also have problem Rob can you help ?

[@lenfordmason4395]

I have a 2007 180 compressor, it was doing a lot of hunting and spluttering whilst driving, changed the breather pipes and the valve that comes with the kit from mercedes. 2weeks later and the same issue is back, been told it's a common fault with these cars. I did change the Air Mass sensor 4months prior, any ideas or suggestions, have you had an overcome this problem????? Thanks

[@durimzejnullahu408]

did you ever find out what the issue was?

[@cilkitzvictoria4586]

Yes sir, hope you will answer my question, I had 2009model c200 kompresor, troble code p0045 and it's say supercharger boost control solenoid circuit A open, where can I find the boost control solenoid circuit, tnx

[@leandrobignardi7762]

It must be the egr valve

[@bodgitandleggitgarage]

A homage to Glen he will be so proud we're going to have to make him do it again without wimping out this time🤣🤣🤣🤣🤣🤣

[@bodgitandleggitgarage]

But these days he does like to be called Mr nip pinch

[@ozzstars_cars]

I am honored!

[@user-jy5ym8pi3i]

i don't understand how the STFT was negative, it schould be near the zero can you explain me the reasons and thank you

[@OneAuto]

Because of the vacuum leak (un-metered air entering the engine) the O2 sensor reported a lean mixture so the PCM added more fuel to try to get to the correct air fuel ratio (14.7:1) hence the positive LTFT. Once the leak was fixed the negative STFT shows the computer has/is leaning off the mixture which will eventually bring down the LTFT until they are both + or - approx 6% (In the video you see LTFT 22% and STFT -16% = 6%)

[@wyattoneable]

Easy diagnosis for you my friend. Too bad it was so hard to get to. Nice fix by verifying the trim numbers.

[@OneAuto]

Thanks Wyatt, nice to get an easy diag once in a while

[@s4494r]

That's the vacuum pipe. I guessed that would have been the problem as soon as you mentioned idling problem. Fuck i gotta fix it on my car now!

[@MT-xy7fw]

where are you located. i need to bring the same car to you.

[@emiljanocakalli1778]

whats the oe nr for that?

[@yamafanboy]

Ok if anyone else with this same 271 engine is having this problem only for the first 30 seconds or so after startup like I am; it might be the EGR valve EVEN IF you test with a vacuum tester and the diaphragm appears to be in tact. I haven't taken the valve off yet due to the close proximity to the exhaust manifold but i'm almost 100% certain that the valve is stuck shut since I removed the largest rubber hose bringing air into the valve and I tried to blow on it while the diaphragm was still under vacuum from my vacuum pump but I couldn't get any air to move through the valve to the exhaust manifold. I think that should clearly indicate that the valve is not opening despite being under vacuum.

[@fradrake11]

Hi Rob I have a c 180 which is cranking but just not ticking over to start. I have replaced the four spark plugs and sensor still no jay. Any idea what it can be?

[@dimiz4096]

have you tried the air filter?

[@satamanschmidt3428]

How much did MB charge you for that hose. About $500 or a little less?

[@OneAuto]

Haha a little less, just under £10... makes a change though :)

[@cozziekid]

"Idles like dick slap" is my new favourite phrase, nice one Rob!

[@drewpreston9006]

Sorry to be so offtopic but does anyone know of a trick to get back into an instagram account?? I was stupid lost my account password. I would appreciate any tips you can give me

[@cyruscohen3590]

@Drew Preston instablaster ;)

[@drewpreston9006]

@Cyrus Cohen i really appreciate your reply. I got to the site thru google and I'm waiting for the hacking stuff atm. Looks like it's gonna take a while so I will get back to you later with my results.

[@drewpreston9006]

@Cyrus Cohen WTF IT ACTUALLY WORKED! I just got access to my ig account after roughly 30 minutes by using the site. I had to pay 15$ but for sure worth the price =) Thank you so much, you saved my ass :D

[@cyruscohen3590]

@Drew Preston you are welcome :)

[@michaelbates3709]

Throttle body gasket and or throttle body failure

[@Shandybrother]

simple as that.. sorted! 😂

[@OneAuto]

#Sorted

[@duncangrindley5021]

I have this problem, how much should i pay to have it fixed? Mercedes quoted 550-600£!

[@OneAuto]

The pipe was £10 plus about an hour to do if that

[@duncangrindley5021]

One Auto, thats great! Thanks so much for your help. Keep up the great work 👍🏻

[@dewotion]

Mby u can help me? My engine is vibrating like crazy first couple minutes, until gets warm - then everything works like clock :) same car

[@johnh9200]

They have a known issue with the throttle body and the flap that directs the air down to the Supercharger sticking. It's a pretty easy fix, you need to take the air intake tube off and get access to the throttle body. Get a clean rag and a little non corrosive cleaner and give it a wipe around the inside of the throat. In a day or two you'll notice it improving. It's nothing to cause you concern.

[@yamafanboy]

I have this same problem. I thought it might be the EGR causing it. Might replace the entire throttle now.

[@TheDisgruntledMechanic]

A little piece of duct tape would've fixed it! nice easy one Rob!

[@OneAuto]

Yes Mike that would sort it! Cheers mate

[@arcy1318]

@auto I have the exact same air noise in the exact location. I'm going to check the hose you just did. What's the name or Mercedes number for it. Thank you

[@OneAuto]

I can’t remember, the dealer will know, it’s a common problem

[@arcy1318]

One Auto, thank you boss man.

[@ka5269]

was that water being sprayed?

[@OneAuto]

No, brake cleaner

[@haywardsautomotive6156]

HAHA never heard a dick slapped engine before but it sounds like a sucker to me. Nothing like a new rubber to fix a dick slapper...:D

[@OneAuto]

It’s the latest automotive phrase Bob... I like it 😂 (Blame Leon and Glen ozzstar for it)

[@haywardsautomotive6156]

Wonder what Leon's customer said when he told her that...HAHA He'll then call it a real face slapper :O

[@flatratemaster]

😂😂😂😂

[@jalatecompa]

do i need to remove air box to fix this hose?

[@OneAuto]

Yes sir

[@jalatecompa]

@@OneAuto thnx i will do it

[@Badgertronix]

The owner only noticed the low idle not the terrible fuel economy he probably had? Well slapped that man

[@OneAuto]

He actually bought another car because of this 😃

[@carlford8646]

I hate doing those they are a pain in the backside

[@OneAuto]

They are.. it’s the big spring hose clamp low down at the back thats the worst. I chuck it away and fit a Jubilee.

[@Diagnosedan]

Nice job! Had the same one last week! What is Dick slapping by the way😂Not sure it has anything to do with fixing cars😎

[@OneAuto]

Nice. When Merc have the pipe in stock, you know it’s a common problem.

[@messaoudiabdelkader7994]

Problème

[@8ile]

How much did Merc want for that pipe at the dealership?

[@OneAuto]

£9.30 inc vat and in stock!!

[@8ile]

You have to pay VAT when you own a garage? I've had nothing but nightmares with Merc dealership. Don't supply automatic gearbox on a A140 with a dipstick... They wanted £75 for a dripstick. Drove the car to the scrap yard seeing as it had other problems as well.

[@OneAuto]

A wise decision 👍

[@throttlebottle5906]

it hates it's name so bad it wants to die :))

[@Eshkani1]

What's the point makeing the video you don't even show anyone where you actually got the pipe from you just point there so many parts you got to actually show where it is not everyone's a mechanic

[@OneAuto]

Your answer is in the title #Quickclip When your in business there isn’t always the time to make a video so a quick vid showing the symptoms, hearing the air leak and marking the area where the hole is with an arrow is as best you get. The video tells you to get the pipe from Mercedes and shows you the old pipe so you know what to look for. So if you’re not a mechanic, you now know what the problem is. If you have any level of competence as a DIY’er you might want to attempt it yourself by figuring out how to remove an air filter box. You may look at it and think ‘I can’t do that, I’ll take it to a professional’ Or you may decide to just go make stupid comments on people’s YT videos. Either way thanks for watching and adding to my advert revenue.
