Hello 👋 If you hear carefully, you will notice a small noise coming from compressor. It’s 100% normal with over 150K Km But if you need to hear the engine how it sounds, you will need to take off you belt that drives the compressor then check if your engine is healthy or not

@A1Frepairs My car is not even 80 thousand km old and we bought it as new in 2011, so I am the first owner, but the sound just caught my attention. It was always at the beginning, but I didn't know if it was normal or not. When should I change any chains or belts?

Yes it’s mandatory Not fun but u need to do it

It should work !! Are tou sure everything is OK ? Nothing broken ?

Crappy engine Injectors were not adjusted properly

Thank you Indeed you need to bleed the brake fluid It’s mandatory after messing with lines Also it’s better to do it with INPA (BMW procedure) that will automatically tell you when and which brake nipple to open and close

Thank you!

I had this exact question thanks

If we don’t have INPA just do each tire one at a time

Hello In my case the engine was dancing After that I bought a set of 4 injectors used but redone by a specialist Installed them then I did the adjustment All of that after I checked the timing (very important) Engine 100% OK

@@A1Frepairs A ok . I also think that one of my injectors sometimes dies and sometimes comes alive. But I don't know which one. All are the same on diagnosis.

The sound was exactly like when I moved it On bumps for example it did the same thing Like metal touching metal So it was the small part in the video, parking brake braket that was loose inside It took me a lot of time to find it

@@A1Frepairs did you notice any noise when driving slow like coming to a stop mine makes that noise also it’s coming from the tread tires and when I hit a bump it does the noise in your video

No bro it’s was a very bad oil filter housing gasket (fortunately for me)

By releasing the pressure, creating atmospheric pressure in the cooling system, the boiling point of the coolant goes down. Therefore it boils. If you leave the cap on, it shouldn’t boil.

😅😅

Yes I think timing problem

😂😂😂

It’s a simple small tool from KStool Here is the link : amzn.eu/d/0E2nMee

@@A1Frepairs Got it out :DD

It was not easy 😂

It was this hose for vacuum pump

Hello Nothing is wrong with this engine at this time. What do you think ?

Hello, thankx for the remarks You are kind of right about lubrification of premium fuel that OEM recommends. The car is from 2005 engine still running great. I have been running e85 without this kit for a year now and no problem at all I wanted to add this kit as it helps with the mixture inside the engine. Regarding plastic and rubber, yes the e85 is a bit harsh on them but still if something goes wrong I will replace it (part of maintenance) Let me tell you : e85 (0,9€/liter) vs e98 (1,98€/liter) I’ll let you do the math 🙂

@@A1Frepairs I have a California SULEV N51 328i and catalytic converters which my car has 4 goes for $1500 each, E85 keep catalytic converters clean, so I would add those $6000 plus labor to the flex fuel money saving.

@@A1Frepairs i have flexfuel too on my n52 but do you run 50/50 petrol and e85 or just only e85

Thankx man Greatings from France 😀

I have some codes related to the mixture control : Bank 1 and 2. I'm not sure if it linked to this leak. It's the only one I could find in the engine

Do it say p0 some

Is that noise coming from the car on

It sound like a vacuum cleaner

If so check behind the valve cover

Have you found the issue?

Hi, are tou sure it’s the only thing you did ? Maybe the quality of the seals kit you bought sucks or your pump it’s dead !!

Hello bro, It’s written in the end of the short 🙂 PCV system was bas. Replaced it, everything was fine

You got fault code low air mass and no vacum under valvecover

Have replaced the MAF in my n52, rough idle when pressing the brake on cold starts, any idea what it can be ?

@@grindoverfearbad maf sensor or is disconnected

Yes I think you are right. From my point of view, this sounds os coming from the supercharger. After this short, i removed the belt and engine sounds really OK

Every engine has it’s problems 😂

@@A1Frepairs Yeah, that's true. The M272 is a great engine though...love my C350.

Is this m272? Nice I have in my 2010 glk 350. Great engine .

Lol you sound like you’re 5

If you buy after 2007 and apply oil stop fix CLK is bulletproof

That's for petrol not diesel

Hello, Sûrement tu as une fuite oui En fait c’est plus compliqué que ça : - Ca peut être une fuite admission - Ca peut-être aussi un problème de MAF - Problème injecteur Moi je vais changer ma rampe d’injection, j’ai déjà mis un nouveau OEM MAF Mais surtout la vidéo c’était pour régler : Certaines fois, je m’arrête au feu rouge, le moteur se coupe ! Depuis que j’ai fait ça c’est good

Hi What do you mean by clicking noise ? If you injectors : completely normal ! If you mean lifters : it goes away after 10/15 min, if not you have a problem.

If I remember well : 15Nm + 90degre Double check please !

Hi man How you doing ? You mean when you plug the tester with the blue fluid, the cooling system boils before the liquid turns yellow ? If it’s the case, I’m afraid that your water pump does not work at all -> simple way to test it : check bleeding procedure for N52. If the pump turns ON you will hear it. Otherwise : big leak if the head gasket ! 🤞

@@A1Frepairs Yep, even draining a lot of the coolant before starting this procedure. I also have oil disappearing (without leak or smoke), plus few days ago the catalyst converter threw an error about being out of range. I guess it's the head gasket, but wanted to make this test as the cooling system had a lot of leaking hoes that were replaced. But even then the coolant kept falling down. Oil consumption is around 0.3/0.4l at 1000km Coolant loses a bit more. But still no visible smoke from the exhaust or leaks under the car/on the engine. For the sake of knowledge, I'll try the procedure and let you know the result. Thanks mate!

Welcome Let me know when you do the test

@@A1Frepairs The pump is looking fine, ejecting water with good pressure. I've arranged an engine inspection by a 'good' mechanic and possibly head gasket replacement.
