MAJOR Common Issues On The CLS 550 Its REALLY BAD 😳 

That’s good to hear! As soon as I figure these issues out will be doing the same thing!

@@Redlineracinggarage can’t wait to see it homie 🤘🏻

@@vladislavyanpolskiy4437 🤙🏼

@@vladislavyanpolskiy4437 Never had an issue lol...Cool lie...Mercedes need the computer replaced after 100k miles for 4k...The radar sensors for the blind spot also go bad. I have had 4 Mercedes and had the same problem with all of them...After 100k its best to sell them...Otherwise you will have 5-10k in repairs at a minimum. I actually have my cars unlike the people who just make up the "had no issues" without even seeing their car. There isn't a 550 in the world that didn't need the valves replace after 100-130k miles...Never keep a Mercedes past 100k miles unless you can't really afford one in the first place, like most old Mercedes still on the road.

@@pete64041 lol well it’s nice to say my car isn’t even close to 100k miles then isn’t it 😁

I’m glad you did! Keeping that M278 healthy! 💪🏼

How much cost you to do that

@@aknation4418 about $2k CAD

@@Redlineracinggarage thanks a lot bro

@@aknation4418 no problem

Ahhh that makes me feel a lot better lol!

What sort of noises? I have typical loud injector noises (ticking almost) but no codes or lack of power at all

@@tjholdings736 well the injectors are a separate noise but this is a ticking/rattling sound. I have no engine codes and no lose of power which is weird

Camshaft gear adjusters are a common issue for the rattling noise. (Intake side)

Sickkk! Thanks! Appreciate it

Welcome 😂😂 yeah I had to share the story brother! And looks like alot of ppl having the same issues! Gonna get it fixed and then we’re gonna go all out on the CLS !!

Your welcome ! I got it from a professional shop that deals with European cars. They ordered the check valve from Mercedes directly. I would highly recommend a expert on Mercedes to do the work it is a complicated car. It’s better to spend a little bit more money but knowing you have a piece of mind! That’s my opinion!

@@Redlineracinggarage thank you!

Hi Mali, you can also order it from here as well. I have these check valves and tensioners on my car. All oem mercedes parts www.fcpeuro.com/products/mercedes-timing-chain-rattle-repair-kit-genuine-mercedes-278050

@@daltonlordly8145 thank you

Yeah v8’s are fun I can’t lie but expensive to maintain that’s for sure

No they're not

Its from inside of the strut, you basically have to change that whole strut

At this point I’m not sure what to do. A lot of people have different ideas . But thank you for your opinion I will take in into consideration when I’ll be digging into this thing again 😆

yesterday i was driving my cls and all of a sudden the engine noise got really loud… it got like really loud like i had a noisy exhaust pipe… do you know what it is?

​@galodoidousarenato5504 Maybe the main fan by the radiator? During summer if I turn on the AC to max, my CLS sounds like a jet starting up because the fan spins at max speeds

@@virtuethoughts thanks bro for help , my exhausted broke hahaha i fix all ready

@@JerelLorenzo thanks!! It had a leak, but before the leak it had a really nice noise, after I told the guy to fix it it was completely silent, I don't hear the noise from the V8 anymore, I think I'll put the pipe straight, or delete some muffler

Super crazy expensive man!

Have to learn how to work on them Yourself

Nice! Well in my opinion both are great options but the reason I went with a x pipe is because the big resonator is already connected with the 2 exhausts and it’s there for a reason to create more back pressure. But also that the 2 exhausts are connected and the turbos communicate with each other via the exhaust. That’s the reason I did a x pipe

The tensioner goes bad because oil changes were not done on time

Check valve LOL

@@thomasrose6962 sorry what is the LOL for? I understand lack of maintenance would lead to tensioners failing and check valves would be done as well

😅😅

I would advise to change the check valve to preserve your motor the sooner you do it the better!

Mine is a 2012

How reliable has your s550 been

Thats very weird maybe check the trans fluid, and yes tensioners and check valve very important

@@Redlineracinggarage I put 10w50 Mobil 1 in it with Lubeguard additive LX ester technology and the noise stopped on the chain rattle at start up. Yeh not sure what to think. We are going to do a transmission fluid and filter ASAP within liqui moly from FCP

@@Redlineracinggarage was thinking maybe conductor plate?

Try ebay they might have it

I still think the CLS 550 is the better motor

Yupp they are cheap ish to buy because it’s issues after issues mine has 178kms on it and I’m planning to sell it at about 180-185kms because I feel like around the 190-200kms everything will crap itself. With cars like this it’s basically a hit or miss!

I got a chance on a 2014 cls 4.6 twin turbo with 90K for 21K will it be a nightmare?

@@dojocho1894 at 90k you should be alright its really low milage just make sure you keep up with maintenance!

@@dojocho1894 keep oc with maintenance and especially do not do back to back runs. That’s when the turbos get really hot and crack the coolant lines. Stay on top of maintenance and you will be gold.

I’m thinking about doing something that might prevent the oil in the wiring harness. If I squeeze some black rtv sealant in the lines and zip tie the ends, maybe it will prevent the oil from wicking it’s way around the motor into the ecu.

5.5L much more reliable !

Mine was lifter tick

@@Redlineracinggarage did you change the lifters? or used the hydraulic lifter cleaner?

@@dwighthoram no i didn’t change the lifters and i didnt use the cleaner either but thats your best bet to use the cleaner and see if it helps

It’s right in between the cam gears and it’s basically a small round cylinder

Your loosing fuel pressure, did you change the fuel pressure sensor ?

@@Redlineracinggarage after changing the fuel pump do I need to change the sensor because I have the same code and car is driving fine?

@@ahmed559900 you might have to change the sensor if it’s still coming up

I’m not sure because I’m not the one doing it but I don’t think so because your only removing the tension from the timing chain, you’re not really moving the chain

I would do the check valve on it, thats number 1. While your in there you can do the timing chain and tensioner. The kms are pretty low so it makes perfect sense to do it all now so you don’t run into issues around the 160-200kms

Yeah, it sucks how sensitive everything on these Mercedes’ is ! You gotta really be careful how you drive these things. It’s no joke!

Cheapo tires. Nothing to do with the Benz

@@se6586 they might have looked good but might be old so basically their shot. I gotta check the date on them later. But they were not cheap, Michelin pilot sports ( not a cheap tire )

@@se6586 mine were def not cheap, payed 1,300 with labor at the cheapest shop in my area for Pirelli P Zero Sports performance tires and were about 7 months old

@@Redlineracinggarage yeah if you have low profile tires, any major pothole is almost wraps lmao

Not sure all i know is check valve 😅

It’s basically the same motor just bigger displacement, with bigger turbos. So any issues with this motor would be the same in the CLS 63 ( in my personal opinion )

Yes it is a enjoyable car that’s for sure! But I highly recommend looking into the common and major issues on these vehicles

Good point! 😂 I didn’t think of that!

Yeah I know the injectors are loud. I hope it’s the check valve and the tensioner and it’s about $2500 to get that all done $1500 for parts and about $1000 for labour

Owners Manuel require 91 octane and a additive to stop knocking

@@danteg4534 a fuel additive?

@@Redlineracinggarage owners Manuel on my cls 550. Add a Mercedes approve fuel additive

@@danteg4534 ahh got it! I’ll check it out! Thanks for the advice!

Yeah that’s what it comes down too. Maintenance.

Its a check valve that stops to work and spills oil from the head back down into the block. So you start losing oil pressure in the heads which causes major issues

I would go for it its really low milage

@@Redlineracinggarage Ayeee! I appreciate it thank you

@@yaboichris4800 anytime!

Did you end up getting it?

About $2k CAD

It’s basically right behind the tensioner if you google it you will find it

Yes the bags are failing you will need to get that checked out!

Dont buy the 550, got a bad rep and usually break down. Go for the 500 or the 63 if you can. Way more reliable.

Id watch out for a Lexus and buy the Lexus lol

@@DR-nw7xn Yup, easily the best option lol

Yeah I don’t blame you!

😂

I haven’t done it myself but i know its located where the heads meet behind the timing chain tensioner

I think it could be your rear bags are starting to leak

@@Redlineracinggarage I really have no clue if it happens again I'm going to start looking for the issue

@@virtuethoughts there is a button with a arrow pointing up you probably know which one I’m talking about. Hit that button. It will fill the bags up to its maximum capacity, Let the car sit at idle for about 10-15 min and see if the back drops, if it does the. Your rear bags are leaking.

@@Redlineracinggarage okay perfect thanks

@@Redlineracinggarage should I turn the button off tho after its fully filled up?

The 09 is a different generation they come with no turbos i would say just make sure the timing chain is good

No,you can find them cheaper

Nope zero codes, nothing !

Mines came with the car, they probably sell them on www.fcpeuro.com check it out!

@@Redlineracinggarage they only has tail lights any other suggestions?

@@dghost7236 try amazon, ebay maybe

Damn that’s for sure 🤣 if you go the Mercedes to get that done you will definitely end up paying 10k.

@@Redlineracinggarage if you were me, would you fix it or just buy a new car?

@@Jayynoz. I don’t think it’s worth fixing especially for 10k if it was somewhere around the 4K mark I would. But it also depends on how much money and time you have invested in your car so….

Yeah your absolutely right, I think that the best thing to do is get a brand new German car and drive it till about 100k then get rid of it because that’s when the issues start coming up.

Thats interesting to hear. I have a first gen 2008 CLS550 with 207k miles and ive never had any engine issues, just normal maintenance and it still drives like new. Was thinking of getting a newer gen but this makes me weary. Plus the first gens are easy to work on and replace things like air struts etc

@@00700556 yeah if the first Gen isn’t giving you issues you should keep it and enjoy it. As for the second Gen, so far iv owned it for about 6 months and all of a sudden I’m dumping thousands into it. Hopefully when everything is fixed it will last a while before I spend money on it again 😂

@@00700556 thats a very reliable engine tho

@@scottp6761 Is shit he still not fixed it. BMW is much better I had CLS too

Not yet but I assure you they will eventually

@@Redlineracinggarage I’m thinking my finally has gone on me. The car will always rise up without issues. But as soon as the car stops or is shut off. the front right starts to drop. Then the other three sides begin to drop. At first I thought I could narrow it done to something else but I’m assuming it’s the whole shock and bag.

@@Redlineracinggarage the roads in Toronto are so bad since owning the cls I’ve spend more on fixing rims then any other maintenance lol

@@haydon9032 yeah tell me about it last month I hit a medium size pot hole and messed my my entire strut and bent the rims and my other 2 rims where bent already from before so that’s 3 in total for these Toronto streets!

There’s a leak in your air suspension somewhere. It could be front or back, the tries to compensate thus the sagging on both sides or back to front. I replaced my entire suspension on my 2013 CLS with BC Racing so the car is essentially stuck in sports mode.

Its in the heads right behind the timing chain

@@Redlineracinggarage Okay 👌👍 Thank you sir

@@juancamaney3562 np! Anytime

It actually was wastegate rattle

Yeah that’s for sure!

I don’t think so, he was a mature 40+ year old architect.

Me too! 🙃

@@Redlineracinggarage let me know how things go with that engine rattle at mcnallys

@@corrado9076 will do! Should be this week apparently the head mechanic got sick last week so nothing got done on it

Low milage only brother, after about 100kms its a hit or miss depending on the maintenance durning that 100kms

2012

@@Redlineracinggarage what about a 2011 with only 10K kms? What should I look out for ? It’s one owner and no accidents!

The 2011 is the last year of the first gen and they can n/a no turbo. Just look out for timing chain and tensioners

Please help me explain what this balance shaft issues is

@@Redlineracinggarage balance shaft holds the gear that attach the timing chains the teeth are worn out that makes chain slack and ruins the chain and soon or later the chain will skip and destroy the engine I owned Mercedes all my life this can occur from early as 70k miles and yes it’s very costly to repair that’s why if you research many Mercedes owners have that problem and no body can find what is that tiking noise

@@konstantinostselios1129 thats good to know man i appreciate your input, so its basically the timing chain guide

Iv replaced the check valves and tensioners and still have the same noise. It could be cam adjusters or lifters

Lifters

@@Redlineracinggarage How Lifters can you explain please?

@@henzo7087 lifter ticking is in the heads when the cams move the lifters also move about the valves. Over time it causes a ticking noise which is very common on german cars. Reason for that is because when the car sits for to long and oil isn’t replaced as it should. Thats my opinion there are several others

164kms

CLS 550 is a 4.7 v8 biturbo The CLS 63 is a 5.5 v8 biturbo

So what you're saying is I really want the CLS 63
