Thanks Man...This helped me on my c200 w204 ..271 engine..Car performance is a wow!!

[@YusufPetersenCPT]

Im glad it helped hey thats what im trying to do is help shot go do some skids man lol

[@thatayotlhemalobela4168]

So this kind of fault reduce performance? Mine goes up to 160km/h. C200 kompressor

[@YusufPetersenCPT]

Yes it does affect performance my car felt like it was in limp mode until i mash it hard then the computer registers and shows an engine light.. its effectively a boost leak and car will drive fine just not at full boost.

[@thatayotlhemalobela4168]

Thanks alot. What about performance if the engine light is left on? I have replaced it and the power improved a bit or should I wait for couple of days?

[@YusufPetersenCPT]

Engine light should be reset wont be full power till its reset adaptations. Maybe engine light will go away after some restarts not sure i havent been through that

[@Lucky13Customs]

Nice hack there dude! When lockdown just started last year, my fiance's Jeeps rubber boost pipe tore ( For the 2nd time ) and they wanted 3.5k just for the replace the stock part. So I welded a custom Aluminium one and got some silicone couplers for 1K and havent had an issue since xD

[@YusufPetersenCPT]

Yeah bru sometimes you just gotta laugh in the face of OEM replacements. 😅 but ok you went next level 👌

[@mogomotsiramorola]

PO491/P2187 The mixture of cylinder 1 is too lean. Don't know where to start cause it states many possibilities, where can I start? Can it be a mad sensor

[@YusufPetersenCPT]

Lean mixture on just one cylinder can mist likely be a faulty or blocked injector if all the others are ok leads me to believe it's fuel related in that cylinder could be a spark plug but then it would be rich with less spark.

[@mogomotsiramorola]

Thanks will try injector cleaner first

[@r77gan]

Cheers Boet! I'm in Australia car only driven on weekends and drove fine on cool days or mornings then went into limp mode in traffic or warmer days. Car is well maintained and iv got 250,000k on her now, thanks heaps for your help with this, ive just changed this boost pipe this morning and she is running great. Problem solved

Oh man I have long ago thrown away the paper I drew it on I think I commented it here someone for someone must just check will update soon.

[@anasalnsour9372]

I have a fault code stating I should check air intake vacuum engine

[@YusufPetersenCPT]

Thats most likely a vacuum leak could be that common vacuum hose under the intake manifold if its the M271 engine could also be boost leak.. see if you are making the right amount of boost first if not then most likely a vacuum leak. Hope this helps.

[@Wd3171]

Hi what was your fault code please?

[@YusufPetersenCPT]

P2263 AND P0299 power train boost leak issue so i just had to find a boost leak and that pipe was the smoking gun.

[@lelomhlongo]

Thanks a million for the video bud. I had high fuel consumption and no power bit didn't have an engine light fault. The mercedes dealer wanted R1068.00 for a new pipe. Got a 100mm length of boost pipe from Parker store in R50 and cut it to size. Problem solved.

[@YusufPetersenCPT]

Brilliant im glad and turbo boost pipe is way better than the stock piece that mercedes makes... full boost all the way!!

[@TheYoungWarlock]

Did you get the error “The Boost Pressure Deviates From Specified Value”? Because I keep getting this issue and my car goes into limp mode when I’m driving up a hill

[@YusufPetersenCPT]

I just got a boost system fault code on the reader that i have that should be the same discription as it doesnt see the right boost or low boost that made my engine light come on. The car feels very weak when the engine light is on there's still some power but i can assume thats some sort of limp mode. So once the leak is fixed i cleared the code and car drove just fine ever since. I reset adaptations at the mechanic but that doesnt have to be done as the computer will correct itself after the code has been cleared.

[@TheYoungWarlock]

Yusuf Petersen I’m getting the code 3539 and 2263 so I’m not exactly sure what the problem is. Mechanics tell me different things to replace including boost sensor but I think I should give your way a try before going into any of those other ones

[@YusufPetersenCPT]

@@TheYoungWarlock it could be a couple things yes but i would check that pipe first its a common issue i was told and if thats where the leak is then great but if its all fine then most likely a leak somewhere else or a sensor issue checking there first would be the cheapest easiest fix.

[@TheYoungWarlock]

Yusuf Petersen thanks so much for your advise! I think it’s not the sensor issue because the car only goes into limp mode when it’s going up hill, which means there’s a leak and pressure is leaking when the car is under pressure

[@YusufPetersenCPT]

If i look up that 2263 code its the same code i got pretty much talking about something with the turbo charge boost performance so we could be on the right track.

[@TheSnuggs01]

Great fix, is that a C180k? What’s the part number on the sc? The reason I am asking is you are getting 14psi boost, which should be a C230k. I am looking for one of these sc’s for my VW G60 engine and I need 14psi boost, what I understand is the C230k has the same compression ratio as my G60 engine, so a good match.

[@YusufPetersenCPT]

Hi nope its a C200K I dont know the part number its a stock M271 engine i believe the 180k is the same engine but that is stock boost when i look it up. There is a smaller pulley kit to make more boost on that sc if you want.

[@TheSnuggs01]

@@YusufPetersenCPT Hi, thanks for the reply, the C180 & 200 have the same sc, just different compression ratios, the c180 is 10.2:1 the c200 is 9.5:1, the C230 has a different sc and a compression ratio of 8.7:1. I gather that the ECU limits the boost on the bypass valve, so I will need to find a c230 sc, thanks for the assistance.

[@YusufPetersenCPT]

@@TheSnuggs01 no problem yes i still have alot to learn about this stuff i know the c230k sits on the other side of the engine yes so it will be different. Hope you get right its gonna be a mad build

[@israelmagagula5120]

Hello my mom's mercedes has lag , I'd put it in sport mode step on the accelerator flat then it would lose power before it kicks in. What could the problem be?? 🤦🏾it also has poor idle it Shakes when idling as if it wants to move. Please help it's a w204 c200 kompressor automatic

[@YusufPetersenCPT]

Oooo could be a few things. Start with checking for good spark plugs, then for any vacuum or boost leaks there shouldnt be much lag it should just kick down and go. Watch my latest video where i go to the drag strip and see if it pulls the same as mine.. remember im stock just removed cats. Rough idle could be the gears are going or it already skipped a couple teeth on timing. Its gonna involve some checking im afraid to rule out things. Could also just be that idle valve pipe that sits underneath the intake thats a common issue, the pipe tears and it creates a vacuum leak.

[@israelmagagula5120]

Hi there, can you help me with a diameter of that silicone tube? Im asking you to help me to not do the job twice, ine for taking measures and one after that tube arrive

[@YusufPetersenCPT]

Ok found it in one of my previous replies in the comments the OEM piece of plastic interior diameter is 60mm. The replacement boost pipe I got I think was 64mm but the OEM clamps clamped it down to seal it nicely so if you going to get a boost pipe 60mm diameter is best but know that a 64mm one worked.

[@YusufPetersenCPT]

The oem plastic pipe inner diameter is 60mm the replacement boost pipe I got is a 64mm piece but it still clamped down using the clamps that was on there and is still working good.

[@YusufPetersenCPT]

Yes this one is the whole thing the video before this was a normal vlog and just at the end of the video the light comes on and it goes in to limp mode its an easy thing to check get it off and see if it's cracked if so its the smoking gun to your problem and can be easily replaced.

[@bosspickleschannel9102]

My w204 c200 has a very very rough start & idle....please can to advise on some of the potential issues 😰🥺

[@YusufPetersenCPT]

Hey there if all else is normal that you know of and you have the same m271 engine it could be a couple things. 1 the timing chain is stretching and on start it's slapping around and idle will be rough. 2 you have that common idle air pipe leak under the intake manifold. And 3 worn engine mounts or a combo of these things. It should start farely smooth and idle smooth if everything is in order.

[@hebertsantos1861]

Hello, thanks for the video, very good!! Could you tell me what is the maximum PSI that reaches its maximum boost? Thank you

[@YusufPetersenCPT]

Max boost I saw by me ever was about 14/15 PSI that's about right the C200K should be seeing around 1 bar and the C180K should see about 0.8bar if im not mistaken they have different pulley sizes.

[@jasonwade3933]

Hi pal, am I right in assuming that you have rectified overboost in your is it possible that you could possibly explain it to me as best you can and as to what you think caused the and also what exactly you did to rectify the overboost

[@YusufPetersenCPT]

It didnt overboost it just cracked and broke and there was a lack of boost felt like the car was in limp mode just running on engine and no boost. The new pipe fixed the issue.

[@muchiefire5235]

Hi, my W204 C200 Kompressor is having the same problem and the error code is P0046, could it be the supercharger or the boost pipe

[@YusufPetersenCPT]

First check boost leaks the supercharger is fairly robust. If its the charger then thats alot of work. Boost leak is easy to check for.

[@muchiefire5235]

@@YusufPetersenCPT Thanks a lot, l suppose checking for leaks is going through the intake manifold all the way to the intercooler. Can I check for this whilst the engine is running

[@YusufPetersenCPT]

Yes the front intake pipe runs all over so there can be a leak anywhere best way is to get a diagnostic tool to check boost amount you should be seeing 14psi if its like 5psi or something low you defs have a leak.

[@trevorm6197]

Just tested mine and it's leaking seriously, where can I get that pipe, the hack pipe?

[@YusufPetersenCPT]

Yes that pipe cracking is very common I was told it by a mercedes mechanic hence I thought let me find another way rather than just replace with the OEM. It's turbo piping connection I got from my local car mods accessories shop. Turbo shops should have it just take oem one with to match size you won't get the same size its a weird size but the one I got was very close

@YusufPetersenCPT thank you so much, will do just that 🙏🙏🙏🙏 I need my power back

[@lukejoseph2383]

Hi I have same car but am wanting to change supercharger pulley how hard would that be. Do I have to remove the supercharger or can I just do the pulley it's self and is any heat treatment needed to fit etc

[@YusufPetersenCPT]

Good question i looked this up a while ago if you have the c200 Kompressor you already have the smaller pulley the C180 has the bigger pulley. There is an even smaller pulley aftermarket that can be put on and yes its a press fit style so you have to pull off the old one and warm new one and put it on it can be done on the car but its very tight to get the pulley puller in.. Some put on a larger crank pulley that increases boost too i see around 15psi boost and im stock.

[@lukejoseph2383]

So the pulley that is on mine is 72 mm going down to a 62 yes it is a c200 w204 2008 auto but when I go to pull past someone I have to put accelerator right down for it to change down but even then it still doesn't feel like it's boosting enough

[@YusufPetersenCPT]

@@lukejoseph2383yep that should be the case. We have the same engine setup as the SLK 200 Kompressor its the best state of tune on that engine other than the C230 but thats turbo. Yes thats how mine felt when the pipe was cracked best way is to get obd and check if there is boost because mine acted up for a while before the engine light went on after a super hard pull from launch once i discovered the crack fixed it and cleared codes then it felt real strong.

[@Benz0411]

Did you have the same thing when starting from cold, rpm too high and sawing. rough engine running

[@YusufPetersenCPT]

Interesting question it was hunting a slight bit but nothing heavy high idle on startup is normal it should drop after a few seconds. Engine behaved normal just low on power it was noticeable. You could have the problem where the vacuum hose under the intake is cracked and and lets in unmetered air that is also a know issue on this engine.

Hi Yusuf Petersen. I have seen your videos. Top. Look, I think I'm always behind you when it comes to problems ahahah. I have this tube with oil. When you had the air leak, did oil also come out of that tube? In addition to this oiled tube, I also have the lower ESP oiled area. The oil doesn't smell like engine oil to me. Could it be brake oil? I really like the W204 and the m271 engine, but after solving the valve cover leak, I now have this one :/

[@YusufPetersenCPT]

If the oil is coming from the ABS pump it is most likely brake fluid its that or power steering fluid if its coming from the power steering pump. Maybe see closer where it is coming from. I hope you come right let us know how you get along. I know theres oil in the intake system that leaked out the boost pipe crack.

[@eduardoa4558]

​ @Yusuf Petersen but your tube is very clean. Did you clean it before making the video? In the video it looks really clean. Mine is all soaked with oil all the way to the bottom. Yes! I have a 2cm crack that section. it seems! What's confusing me is that the oil doesn't smell engine oil! And the brake oil level seems to have dropped! And there's oil under the ESP. Could the oil dirt on the wires under the ESP come from this leak? In your case, did the oil that escaped dirty the bottom of the ESP? Tks

[@YusufPetersenCPT]

In my case all the oil in that spot came from that spot its engine oil that comes out that leak and goes all over it comes from crankcase pressure and returns back into the intake. If there is a leak on the boost pipe fix it then clean that arear with a pressure washer and some degreaser then check again to rule that out. If your brake fluid is dropping its most likely the ABS pump they are known to also fail like that.
