You make removal of the airbox look very easy! It's a real battle... but thanks for your video. I don't have super long pliers to remove that pipe clip, and I don't fancy my chances getting it back on. I'd take it to a MB dealer, but that will cost a fortune. I'm still recovering from having the camchain replaced by the MB dealer.
Before vs after replacing with new MAF what are readings for rpm vs intake pressure vs air flow vs exhaust O2 sensor reading vs air flow?. Idling at 750rpm, my MAF is at 5.3 to 5.4g/seconds = 4litres of air flow second. Air intake pressure at nearly -7.5psig. Voltage from O2 sensor at 0.60 to 0.72. Throttle valve opening normally 17.2%. Air flow of 4.5litre per second vs cylinders total displacement of 11.75 litres per second = ratio of 0.4 : 1 which should, in theory and excluding injected fuel, of nearly -10 psig when piston is at DBC. This is would be indirect indication of no vacuum leak at connections for hoses etc etc. Regards.
hello! I am writing to you through a translator. I have a Mercedes w 203. motor m 271 petrol. automatic transmission, engine size 0.2. fuel consumption is huge, when driving, the tachometer does not drop to 1000 rpm, the tachometer remains somewhere around 1500-2000 rpm. Diagnostics did not find the cause, can you advise what to do?
Waar bly jy? My 180 2006 Kompressortjie het ernstige aandag nodig. 😁 Watse filter, is in die cover wat oor die battary is? Tante weet niks van karre af nie. 🙈 Dit was altyd my man en seun se probleem. My man is oorlede die 1ste Januarie en my seun is amper 'n duisend km vêr.
That round clip that he took off of the pipe you can get similar clips just as jubilee clips and they loosen and tighten where the treads of a bolt attach on to the clamp and when you turn the boat one way it will loosen and and the same in the I think and these jubilee clips for simple fact of you can reuse many many times all you have to do is managed to get your screwdriver into the slit and turn i depending on whether you turn left or right will determined if the clamp will tighten or loosen, I really wish that more verbal information had been given with this to let me know how to fix and there are not that many videos relating to from my experience with my Volvo I had last year it went into limp mode but instead of having a lack of our when I was driving and turned off the engine and turned it back on real quick I would get crazy boost from the turbo and when I start my it is very quiet and very smooth does not splitter at all but I am nearly convinced that when I drove finest open down my I possibly caused a problem with my mass air flow I do not know if it's the mass air flow within the Volvo I had it was a very 2006 Volvo diesel Volvo and a video I watched where a guy who is a bit of a genius with computers in when he puts in his diagnostic computer he reckoned that to stop my Volvo at the time I needed to replace an the solenoid just beside their wastegate
I would recommend anyone that has the m271 engine to get a catch can. Poor design allows for oil to get inside the intake /all the way to the throttle body.
You should tell us? It’s been a month. Im not sure it would hold because the force could possibly make it come off. Might be worth just buying a flexible hose pliers (£15) and putting the hose clamp On, the fact that it’s that tight to get on might be why it’s needed.
The rear ecu connector is full of oil this cars ecu is on borrowed time if the front cam sensors arent replaced and fitted with the oil blocker harness and the harness flushed of oil. This is most likely also why the maf failed the maf plug will also be full of oil. I would pull the ecu and open it and flush the oil from that too with isopropyl before it fails.
My friend, I saw a bright on the cable harness. For a little I left it there. When I read you comment I return to the ECU and there where a lot of oil! Thank you Man!
Nice video, concise, crisp - thank you!

Need special remote pliers for that job to be easy. Got mine from germany
pair of these pliers is like 10-15 usd, well worth to buy them, will save you ton of swearing
Comes out just by removing it alone. Dont have to remove the rest of the things. Thanks for the diagnostic tutorial.
How?
How do reply please
Excellent video . explained to a tea ..thank you
Well done, very informative 👍
Just what i needed, thanks!
nice sharing my friend watching from malaysia
Instant subscription! great stuff mate!
Thank you first class video on job thanks
Very well detailed. Seem quite a bit of work if diy..
What diagnostic tool do you use? Thanks 🙏

I use brute force to pull it up after I release that clamp with the Special Tool,doesn't get out,the Clamp is not holding it :(
Question. Where on the M271 supercharger can you find the Turbo Boost Control Position Sensor?
Watching from the Philippines.
It's inside the supercharger housing
What’s the name of the hose

And where do I install it?
@@GfrigoP good place would be to install it after the valve cover, there is a hose that attaches into the air filter box, there always is oil residue
hello, i couldn’t install the maf hose with the metal clamp back on so i ziptied it very tight, will this be okay?

Yes it will be problem, you will get lean mixture
